options and environment variables that are used by the future.batchtools package.See future::future.options for additional ones that apply to futures in general.WARNING:Note that the names and the default values of these options may change in future ver-sions of the package.Please use with care until further notice.Settings for batchtools futures‘future.batchtools.workers’:(a positive numeric or+Inf)The default number of workers available on HPC schedulers with job queues.(Default:100)‘future.batchtools.output’:(logical)If TRUE,batchtools will produce extra output.If FALSE, such output will be disabled by setting batchtools options‘batchtools.verbose’and‘batchtools.progress’to FALSE.(Default:getOption("future.debug",FALSE))‘future.batchtools.expiration.tail’:(a positive numeric)When a batchtools job expires, the last few lines will be relayed by batchtools futures to help troubleshooting.This optioncontrols how many lines are displayed.(Default:48L)‘future.cache.path’:(character string)An absolute or relative path specifying the root folder in which batchtools registry folders are stored.This folder needs to be accessible from allhosts("workers").Specifically,it must not be a folder that is only local to the machine suchas file.path(tempdir(),".future"if an job scheduler on a HPC environment is used.(Default:.future in the current working directory)‘future.delete’:(logical)Controls whether or not the future’s batchtools registry folder is deleted after the future result has been collected.If TRUE,it is always deleted.If FALSE,it is neverdeleted.If not set or NULL,the it is deleted,unless running in non-interactive mode and thebatchtools job failed or expired,which helps to troubleshoot when running in batch mode.(Default:NULL(not set))Environment variables that set R optionsAll of the above R‘future.batchtools.*’options can be set by corresponding environment vari-able R_FUTURE_BATCHTOOLS_*when the future.batchtools package is loaded.This means thatthose environment variables must be set before the future.batchtools package is loaded in or-der to have an effect.For example,if R_FUTURE_BATCHTOOLS_WORKERS="200"is set,then option‘future.batchtools.workers’is set to200(numeric).Examples#Set an R

A Design of Digital Handheld Terminal in WirelessData Acquisition SystemXingguo SUNKey Lab of Intelligent Computing and Signal Processing of Ministry of Education, Anhui UniversityHefei, ChinaShouxian WENKey Lab of Intelligent Computing and Signal Processing of Ministry of Education, Anhui UniversityHefei, ChinaLei XUKey Lab of Intelligent Computing and Signal Processing of Ministry of Education, Anhui UniversityHefei, ChinaXiaohui LI*Key Lab of Intelligent Computing and Signal Processing of Ministry of Education, Anhui UniversityHefei, ChinaAbstract—In order to make data collection more convenient, quick and accurate in working site in the existing wireless data acquisition system, one kind of multi-function handheld terminal is designed which combines the wireless and wired data acquisition. The paper adopts Atmega128 of ATMEL as micro-controller, nRF905 of Nordic as data transmission module. It designs power management, liquid-crystal display and data storage circuits. The results of practical test show that the handheld terminal can be applied to all kinds of wireless data acquisition networks, and it has several advantages like easy to carry, large data storage capacity, rich function and low cost.Keywords-DS18B20 ; NRF905 ; Handheld terminal ; Data acquisition systemI.INTRODUCTIONWith the popularization of the large amount, cheap and highly integrated wireless module and the rapid development of wireless communication technology, the wireless data acquisition system has been widely used in industry, agriculture, medical and other fields. The existing wireless data acquisition system is composed of a convergent node, basic nodes and the server. The convergent node exchanges information with basic nodes by the radio frequency (RF) module or Zigbee module[1-4].Basic nodes collect information by the digital sensors and send it to the converge node in the form of packet. The data which is gathered by the converge node can be sent to the local server[5]or be transmitted to the remote server by GPRS [6]or GSM[7]. This way need to pay for the expensive network cost, and can not collect data conveniently, quickly and accurately[2].Based on the analysis above, this paper proposes a design scheme of handheld terminal. nRF905 is chosen as communication module which can realize remote transmission. We design the routing protocol which realizes automatic searching and manual setting. It makes the handheld terminal collect data information reliably in any effective area of the wireless network coverage and then display the data on LCD. Handheld terminal has the USB interface circuit which can be directly connected to the computer and allow computer to receive or send commands and data. In addition, it also supports the wired data acquisition, data printing.II.APPLICATIONSCENARIOFigure 1. Network StructureFigure 1 illustrates the network structure of application scenario. The wireless data acquisition system can be divided into three parts: extension, handheld terminal and the server.24LC256I/O1I/O2. . . . . .. . . . . .DS18B20. . . . . .. . . . . .. . . . . .. . . . . .DS18B20. . . .. . . .. . . .Figure 2. Extension Structure*Corresponding author.National Conference on Information Technology and Computer Science (CITCS 2012)Extension structure is shown in Figure 2. According to the received instructions, the extension samples the data of temperature and humidity and then transmits to the handheld. We use DS18B20 and SHT75 as temperature and humidity sensors respectively. The circuit of temperature data sampling adopts 1-Wire single-bus mode, so multiple temperature sensors can be mounted on each I/O port. In order to identify the physical location of DS18B20 and to facilitate the server data management, the corresponding layer information is written into the DS18B20 alarm trigger register[8]. When it’s power on, the extension reads DS18B20 ROM serial number and the layer information in alarm trigger register and then store ROM serial number in 24LC256 according to the different I/O ports and layer information. The physical location of DS18B20 can be determined according to the ROM serial number’s store address to realize the effective data management.Handheld terminal works as a convergent node in the wireless network .It collects the data of extension through the nRF905 and transmits it to the computer through the USB interface. In the working site, handheld terminal can search extension through the routing discovery menu and establish a routing table. According to the actual situation, we input an extension’s address. The handheld terminal will set up a path according to the routing table information to realize communication with the extension. The data will be displayed on the LCD after processed. Handheld terminal has data storage, data printing and cable numbering functions. Cable numbering can facilitate system maintenance. When an I/O port of a certain extension appears bad points, these points will be identified through measuring temperature. Handheld terminal ignores these bad points and rewrites layer information of other sensors through cable numbering function. In addition, handheld terminal can collect temperature and humidity data using wired way through link it to cable together directly in the following two cases. One case is that some small temperature and humidity acquisition systems will not use wireless extensions in order to reduce the cost; the other case is that the geographical position is too scattered to suitable for networking.The server transmits specified instructions to handheld terminal through the USB interface. The handheld terminal sends these instructions to the corresponding extension node through the wireless network. With this, the data can be gathered and passed back to the server. The server completes data analysis and management.III. D ESIGN OF HARDWARE CIRCUITHardware of handheld terminal consists of several parts,which is shown in Fig. 3.Figure 3. Hardware StructureA. Control ModuleThis paper chooses a low power consumption, high performance microprocessor Atmega128 as main control chip, which makes the handheld terminal processing faster and working longer. This module is a core control unit of handheld terminal. It obtains instructions from the keyboard and coordinates the whole system.B. Wireless ModuleThe wireless transceiver module adopts radio transceiver single-chip nRF905 which works in the 433/868/915MHz of ISM (Industrial Scientific Medical). The ShockBurst TM feature automatically handles preamble and the CRC (Cyclical Redundancy Check)[9]. In addition, the nRF905 has stand by and power down modes which can save more energy. The Atmega128 connects with nRF905 through SPI. When transmitting the data, the Atmega128 just sends the configuration register information, the receiver address and the transmitted data to nRF905, then nRF905 packages and sends all data (plus preamble and the CRC). When receiving the data, nRF905 detects the carrier and matches the address automatically. The data is received correctly and the preamble, address and CRC are removed, and then the data is transmitted to Atmega128 through SPI.C. Power ModuleLithium Battery is for power supply of the handheld. The charge management chip is CN3052. In the processing of charging, the system automatically switches to an external power to ensure that the system can still work. Once the charge cycle has terminated, the charging indicator light on the handheld will turn off. Due to the working voltage of printer module is 5V, while the other modules operating voltage is 3.3V. The proposed scheme chooses ME6211A33 as 3.3V voltage regulator and LTC1700 as 5V high-current output voltage regulator.D. Function ModuleThe handheld terminal uses CP2102 to achieve a high-speed interface to realize communication between the computer and the single-chip Atmega128. We use a 128×128 lattice LCD screen as display module and use 2×2 matrixkeyboard to realize man-machine information exchange. EN25B16 is a 2M bytes external storage flash and the data can be stored in it. The DS1302 will support time information. In addition, a printer module RD-OEM57V1 is embedded in the handheld terminal which supports data printing.IV. S OFTWARE D ESIGNThe embedded software of handheld terminal is programmed by C Language with the development of IAR Embedded Workbench, and adopts module program structure design. The main tasks of software include data processing, ask sequencing and job scheduling. When the program stars, handheld will initialize the system, including LCD, nRF905, the detecting of battery energy and the corresponding registers, then enter into the initial interface. User can select menu to complete the corresponding function by keyboard. Work flowdiagram of handheld is shown in Figure. 4Figure 4. The flow chart of the softwareThe communication protocol of the system bases on the master-slave structure. The extension can not initiatively launch communication, and it only has a passive response ability. In the system, each extension has two addresses: one is physical address; the other is network address. The physical address of all the extensions is 0xFF, but the network address is unique. When the extension receives instruction, it will determine whether the address correctly or not. Only the address is correct, the extension will execute instructions and return the data. Data frames format of nRF905 is as following table .ⅠTABLE I.D ATA F RAMEF ORMATType Route Route_Depth Route_ Direction DataType code is 1 byte, it is used to distinguish the different operations. Route is 5 bytes. It represents routing information which is obtained from the routing table. The first byte is the source address, the next byte is the destination address, the last 3 bytes are the relay address; the Route_Depth and Route_Direction are all 1 byte which are used to point to the next address. Data represents the transmitted data. If the data is less than 10 bytes, the remaining bits are complemented with 0. When the handheld failed to send message for 10 consecutive times, we can manually change the routing or alternatively enter the routing discovery phase. The wireless network uses dynamic routing mechanism[10]. Each frame of data contains the routing information from the source address to the destination address. The extension need not do any routing operations. It only transmits the data to the next extension, according to the routing information in the packet. During the routing discovery, the handheld terminal broadcasts RREQ packet to all extensions. If the received RREQ extension address is the destination address of routing requesting, the extension will return RREP packet to the handheld terminal, or it will forward RREQ packet. The RREP packet carries the routing information from the source address to the destination address. The flow diagram of route is shownin Figure 5.Figure 5.The flow diagram of routeV. T HE E XPERIMENTAL R ESULTSHandheld terminal collects temperature and humidity information of sensors which are mounted on NO.3 extension through NO.2 relay extension. NO.3 extension hangs two cables. There are six DS18B20 on each cable. The data results are shown in Figure 6.Figure 6. Experimental resultsVI.CONCLUSIONThis handheld terminal combines the wireless and wired data acquisition. It can detect data of working site by wireless way and collect temperature and humidity information by linking to cable directly. The handheld terminals can still work normally in the environment where working site has various forms or extension structure is complicate. In addition, handheld terminal can also connect with computer and allow PC to realize real-time detection, data backup, data sharing and so on.ACKNOWLEDGEMENTThis project is supported by the National Natural Science Foundation of China (No. 60972040), the Anhui Provincial Natural Science Foundation (No. 11040606Q06), the Provincial Project of Natural Science Research for Colleges and Universities of Anhui Province of China (No. KJ2012A003) and the 211 Project of Anhui University.REFERENCE[1]Chang Chun-bo.

The algorithm introduces the Ghost Bottleneck module and the CBAM module. It reduces the overall computational effort of the model by compressing the network parameters and increases the speed of model inference. It replaces the original model CIoU loss function with an α-IoU loss function, so that the model converges faster during training. This paper replaces the Conv layer in the Neck part of the original network with the DWConv layer. It can reduce the number of network parameters as well as the computational cost, while extracting feature information of different sizes. To a certain extent, it can improve the robustness of the model in terms of object recognition. It was demonstrated experimentally that the original model had a parametric count of 7 095 detection speed of 30.30 frames/s. After the model improvement, the number of parameters of the model was reduced to 2 546 136, the amount of parameters was reduced by 64.12%, the weight file was 5.8 MB, the收稿日期: 2022-06-02;收到修改稿日期: 2022-08-23基金项目: 江苏省研究生科研与实践创新计划项目(SJCX21_1507)作者简介: 张青春(1964-),男,江苏盱眙县人,教授,研究方向为智能检测技术、物联网应用技术、移动机器人、虚拟仪器技术等。

Older VBIOS versions will work with newer drivers. For more information on getting started with the NVIDIA Fabric Manager on NVSwitch-based systems (for example, HGX A100), refer to the Fabric Manager User Guide.1.2. Fixed Issues‣Various security issues were addressed. For additional details on the med-high severity issues, review the NVIDIA Security Bulletin 5211 .‣Fixed an issue with installing the Linux driver where installing the driver interferes with the ipmitool.1.3. Known IssuesGeneral‣By default, Fabric Manager runs as a systemd service. If using DAEMONIZE=0 in the Fabric Manager configuration file, then the following steps may be required.1.Disable FM service from auto starting. (systemctl disable nvidia-fabricmanager)2.Once the system is booted, manually start FM process. (/usr/bin/nv-fabricmanager-c /usr/share/nvidia/nvswitch/fabricmanager.cfg). Note, since the processis not a daemon, the SSH/Shell prompt will not be returned (use another SSH shell for other activities or run FM as a background task).‣There is a known issue with cross-socket GPU to GPU memory consistency that is currently under investigation‣On NVSwitch systems with Windows Server 2019 in shared NVSwitch virtualization mode, the host may hang or crash when a GPU is disabled in the guest VM. This issue is under investigation.GPU Performance CountersThe use of developer tools from NVIDIA that access various performance countersrequires administrator privileges. See this note for more details. For example, reading NVLink utilization metrics from nvidia-smi (nvidia-smi nvlink -g 0) would require administrator privileges.NoScanout ModeNoScanout mode is no longer supported on NVIDIA Data Center GPU products. If NoScanout mode was previously used, then the following line in the “screen” section of /etc/X11/xorg.conf should be removed to ensure that X server starts on data center products:Option "UseDisplayDevice" "None"NVIDIA Data Center GPU products now support one display of up to 4K resolution.Unified Memory SupportSome Unified Memory APIs (for example, CPU page faults) are not supported on Windows in this version of the driver. Review the CUDA Programming Guide on the system requirements for Unified MemoryCUDA and unified memory is not supported when used with Linux power management states S3/S4.IMPU FRU for Volta GPUsThe driver does not support the IPMI FRU multi-record information structure for NVLink. See the Design Guide for Tesla P100 and Tesla V100-SXM2 for more information. Experimental OpenCL FeaturesSelect features in OpenCL 2.0 are available in the driver for evaluation purposes only.The following are the features as well as a description of known issues with these features in the driver:Device side enqueue‣The current implementation is limited to 64-bit platforms only.‣OpenCL 2.0 allows kernels to be enqueued with global_work_size larger than the compute capability of the NVIDIA GPU. The current implementation supports only combinations of global_work_size and local_work_size that are within the compute capability of the NVIDIA GPU. The maximum supported CUDA grid and block size of NVIDIA GPUs is available at /cuda/cuda-c-programming-guide/index.html#computecapabilities.For a given grid dimension, the global_work_size can be determined by CUDA grid size x CUDA block size.‣For executing kernels (whether from the host or the device), OpenCL 2.0 supports non-uniform ND-ranges where global_work_size does not need to be divisible by thelocal_work_size. This capability is not yet supported in the NVIDIA driver, and therefore not supported for device side kernel enqueues.Shared virtual memory‣The current implementation of shared virtual memory is limited to 64-bit platforms only.Chapter 2.VirtualizationTo make use of GPU passthrough with virtual machines running Windows and Linux, the hardware platform must support the following features:‣ A CPU with hardware-assisted instruction set virtualization: Intel VT-x or AMD-V.‣Platform support for I/O DMA remapping.‣On Intel platforms the DMA remapper technology is called Intel VT-d.‣On AMD platforms it is called AMD IOMMU.Support for these features varies by processor family, product, and system, and should be verified at the manufacturer's website.Supported HypervisorsThe following hypervisors are supported:Tesla products now support one display of up to 4K resolution.Supported Graphics CardsThe following GPUs are supported for device passthrough:VirtualizationChapter 3.Hardware and SoftwareSupportSupport for these features varies by processor family, product, and system, and should be verified at the manufacturer's website.Supported Operating Systems for NVIDIA Data Center GPUsThe Release 450 driver is supported on the following operating systems:‣Windows x86_64 operating systems:‣Microsoft Windows® Server 2019‣Microsoft Windows® Server 2016‣Microsoft Windows® 10‣The table below summarizes the supported Linux 64-bit distributions.

HDX hotfix version 2.6.1.3-HF5 provides a correction to an intermittent lip sync issue.The following table lists the other issues fixed in RPX HD Version 2.7.1.Feature DescriptionAudio/Video Calls On rare occasions when placing a video or audio call with the Enhanced UI, the system may have automatically dialed the number before you pressed the Connect button.When viewing an RPX system in a 1080p multipoint call with an RMX 2000 or RMX 4000 with MPMx, you will no longer see a thin black vertical line between cells of the RPX system. For more information, refer to the Polycom® ImmersiveTelepresence (ITP) Deployment Guide.Touch Panel/ User Interface When joining a Polycom Conferencing for Microsoft Outlook (PCO) conference from the Touch Panel, you were not prompted for a conference password, even if a password was required for the meeting.With PCO, private meeting details were displayed on the Touch Panel, even if the Primary HDX system was not configured to Show Private Meeting Details.Known Issues and LimitationsFor UsersThe following table lists the known issues relevant to RPX HD end users.Feature DescriptionAudio/Video Calls The RPX will not accept any incoming audio calls when it is already in a video call.To avoid this issue, place outgoing audio calls instead of receiving incoming audio calls when you are already in a video call.When DTMF tones are heard during the process of dialing an audio call, the near-end and far-end audio is muted for a brief moment.If you hang up an incoming audio call and then immediately place an outgoing audio call, the RPX may not hang up the initial incoming audio call.To avoid this issue, wait five seconds between consecutive audio calls.If the RPX is in a single endpoint video call (such as with a VSX or HDX video conferencing system) and the Do Not Disturb feature on the RPX is disabled, an incoming call from a two-codec or three-codec system will cause the center camera on the RPX to momentarily move to the side before returning to its correct position.If the projectors are in sleep mode when an incoming video call is automatically accepted by the RPX, it may take up to 70 seconds for the projectors to automatically power up. During the 70 seconds that it takes for the projectors to warm up and show far-end video, the RPX meeting participants may not notice that the call has been established.To avoid this issue, verify that the projectors are powered up before placing or receiving any video calls.If the projectors are in sleep mode when a video call comes in, any codecs that are not being used will briefly show near-end video. This only occurs when the number of near-end codecs is more than the number of far-end codecs, such as when a RPX 400 on the near end receives an incoming call from an RPX 200 on the far end, or when either an RPX 400 or 200 receives an incoming call from a single endpoint (VSX or HDX).If you place a point-to-point call to an RMX Virtual Meeting Room (VMR) and then add a site to the call from the Conference List on the Meeting Composer screen (with the Enhanced UI only), the point-to-point call will be dropped and a multipoint call will be created with the VMR as a participant in that multipoint call.To avoid this, hang up the VMR call and then make a new call with the participants that you want in that call.If you are using Meeting Composer and you dial two audio sites concurrently, the Touch Panel may show that you are connected to the second audio number dialed when you are actually connected to the first number dialed.To avoid this issue, when want to connect to multiple audio sites or to both audio and video sites when using Meeting Composer, connect to the video sites first (if any), and then add the audio sites one at a time.When you place a call to an RMX VMR using the following syntax, the call will not go through: IP##MeetingRoomID.To avoid this issue, place the call using this syntax: MeetingRoomID@IP (for example,*************.130.21).Feature DescriptionAudio/Video Calls If you dial an incomplete IP address for a video call (for example, 172.16.254.), you may hear a ringing sound for approximately 90 seconds. Until the ringing ceases, you will be unable to place another call.Content If you share content using a laptop, for best results, set its input resolution to 1024x768 and its refresh rate to 75 Hz. This will ensure that the content image renders correctly.Document Cameras The Eye-10 document camera used in some custom solutions does not support the Freeze function that is available for other document camera models.Touch Panel/ User Interface If you press the Content button on the Touch Panel when no content source (such as a laptop) is connected to the RPX with the VGA cable, the Primary HDX codec will generate a hidden message on the Primary wall screen. The message states "PC input resolution and/or refresh rate not supported.” This message will not be visible onscreen because the RPX is programmed to picture mute all wall screens when the system is not in a call. If you establish a video call while the message is activated, the call will take longer than usual to connect. To avoid this issue, wait three seconds (during which time the message will time out) before placing a video call from the Touch Panel.In an audio call from an RPX to a cellular phone or analog phone, if the remote user disconnects the call first, the Touch Panel continues to show the audio call as in progress. To avoid this issue, manually press the Hang Up button after each audio call is completed. The RPX will not accept incoming audio or video calls when the Hang Up button is off hook.When searching for a site in the global directory with the Enhanced UI, up to nine characters can typically be displayed on the screen. However, depending on the width of the letters in the name, more or less of the site name may be truncated.With Meeting Composer, when dialing a phone number with more than 10 digits, or dialing anyotherlongstringsuchasextension@IP_address(ex:*************.130.201),the string will likely be truncated when displayed in the right-hand pane of the Touch Panel.If you place a point-to-point call to an RMX Virtual Meeting Room (VMR) and then add an audio-only site to the call, the two columns on the left side of the Meeting Composer screen in the Enhanced UI will go blank and the icons at the top of the columns will become grayed-out.When Polycom Conferencing for Microsoft Outlook (PCO) is used to schedule multiple meetings and you select one of the meetings on the Touch Panel, the details for that meeting display on the left side of the Touch Panel screen. If that meeting is cancelled, it is removed from the meeting list; however, the details of the cancelled meeting are still displayed on the left side of the Touch Panel screen.To fix this issue, simply select a different meeting from the meeting list.For AdministratorsThe following table lists the known issues relevant to RPX HD administrators.Feature DescriptionAudio/Video Calls When the primary codec answers an incoming video call, any HDX codecs that are not being used will automatically accept any other incoming video calls if the following conditions exist:1. The RPX 200 Series or RPX 400 Series is in a single endpoint video call with aVSX or HDX video conferencing system (video ad-hoc dialing).2. The RPX 400 is in a video call with an RPX 200 Series, a TPX™ 306M, or a TPX204M.To prevent unused codecs from accepting any incoming calls, use the Do Not Disturb timer. To change the amount of time before Do Not Disturb is activated, access the DoNotDisturbTimer field in the System_Config.ini file. In this field, you can enter a value between 10 and 300, or leave the value at 0 if you want to keep the feature disabled: DoNotDisturbTimer=x where x is the value (in seconds) of the desired timeoutperiod.For example, DoNotDisturbTimer=120 sets the parameter to 120 seconds.If you use the web UI to place a call that is not at the default call speed, the codecs will not automatically adjust to the same call speed. The Primary codec will connect at the call speed specified in the HDX web UI Call Quality field, but the remaining codecs will connect at the default call speed.To avoid this issue when placing a call using the web UI, connect to each codec individually at the desired call speed (if the desired call speed is different from the default).Avoid using the suffixes ‘1’, ‘2’, ‘3’, and ‘4’ for your audio speed dial name entries. Using these suffixes may cause the system to incorrectly interpret them as an ITP suite, instead of distinct audio speed dial entries.Avoid creating directory entries that have an “&” symbol in the name. If you do so, the entry will appear on the site list with the word “amp” in the name rather than the “&” symbol.When the RPX is in a call, sending Telnet commands to change the video format may not work properly.To avoid this issue, do not use Telnet commands to change the video format when the RPX is in a call.If you use the web UI to place a call that is not at the default call speed, the codecs will not automatically adjust to the same call speed. The Primary codec will connect at the call speed specified in the HDX web UI Call Quality field, but the remaining codecs will connect at the default call speed.To avoid this issue when placing a call using the web UI, connect to each codec individually at the desired call speed (if the desired call speed is different from the default).When an RPX calls another RPX in a point-to-point call, the codecs begin to connect one at a time. If network resources become limited, not all of the codecs may connect, which may make it appear that one of the projectors is not working properly. If a projector does not work correctly in a call, you should check if the codec connected. If it did not connect, reducing the call bandwidth may solve the issue.If your ITP environment is configured to use both the LDAP directory and H.323 Gatekeeper functions, and your speed dial entries are not IP addresses, video calls may take longer to connect due to the additional communication involved between the various components in the solution.Feature DescriptionControl System When you connect to the codecs through Telnet or through the Crestron Toolbox and use the command prompt, you may see “overflow buffer” and other error messages when you usethe Touch Panel. These errors also appear on the Crestron log. This issue does not affectsystem performance or functionality.Directory If you add a site from the CMA directory to the speed dial list and then later change the name of that site in the CMA, the speed dial entry name that is displayed on the Touch Panel maynot be updated.To fix this issue, reboot the codecs and the AV2 System Controller. Alternatively, from theHDX web UI, delete and re-add the renamed CMA site to the Speed Dial list.Microphones If you disconnect the Polycom Ceiling Microphone Arrays and then connect any microphones other than Ceiling Microphone Arrays, the proper stereo settings may be lost.If this occurs, launch the Polycom Telepresence Tool, make sure that all the HDX codecs areconnected, and then click Configure HDXs to set the microphones to their correct settings.Touch Panel/ User Interface If any of the HDX codecs are rebooted without rebooting the AV2 System Controller as well, the HDX UI remains onscreen.To avoid this issue, reboot the AV2 System Controller whenever any of the HDX codecs are rebooted. The VNOC, Service, and Site Administration teams are advised to reboot (power up) the AV2 System Controller after the HDX reboots (powers up) as part of the reset process or when recovering from a power failure. Placing a call without rebooting the AV2 System Controller will cause the Touch Panel to freeze.If you reboot the Primary HDX codec while the RPX is in an audio call (with the Help Desk, for example), the Hang Up button on the Touch Panel will freeze.To avoid this issue, reboot the AV2 System Controller when the Hang Up button enters that frozen state.Occasionally, the incorrect video format will be displayed on the Touch Panel Admin screen. To determine the correct video format:1. From the web UI, go to Admin Settings > Cameras.2. Check the Video Quality field for the camera being used. If VideoQuality=Sharpness, the video format is 1080p30; if Video Quality=Motion, thevideo format is 720p60.Alternatively, you can check the Video Format on the web UI Place a Call page.When initially loading the Crestron Touch Panel and then loading the AV2 System Controller, a Toolbox Results dialog box may appear at the end of the installation process. Although this dialog box displays an error message, the installation completed successfully.If users report that the Touch Panel seems to take an unusually long time to return directory information, check if there are LDAP entries in the directory that are no longer valid. If there are such entries, correct them.Where to Get the Latest Product InformationTo view the latest Polycom product documentation, visit the Support section of the Polycom website at .。

DALI Release 0.1.2 Beta (14)Chapter 10. DALI Release 0.1.1 Beta (15)NVIDIA® Data Loading Library™ (DALI) accelerates the preprocessing of input data for deep learning applications. By offloading augmentations onto GPUs, DALI addresses performance bottlenecks in today’s computer vision deep learning applications that include complex, multi-stage data augmentation steps. With DALI beta release, deep learning researchers can scale training performance on image classification models such as ResNet-50 with MXNet, TensorFlow, and PyTorch across Amazon Web Services P3 8 GPU instances or DGX-1 systems with Volta architecture. Framework developers will have less duplication due to better code reuse and maintainability.DALI offers both performance and flexibility of accelerating different data pipelines (graphs that can have multiple outputs and inputs), as a single library, that can be easily integrated into different deep learning training and inference applications.The DALI 0.6.1 is a beta release. Hence, for all the features, the functionality and performance will likely be limited.Key Features and EnhancementsThis DALI release includes the following key features and enhancements.‣Added the DALI TensorFlow plugin to improve out-of-the-box forward compatibility.‣Added a new package nvidia-dali-tf-plugin that allows user to compile DALI TensorFlow plugin using the locally installed version.‣Added the below examples:‣VideoReader‣PyTorch and MXNet examples with various readers‣Added a new operator variant gpu box encoder.‣Added a new JSON parser—now COCO reader start up time is significantly faster (~10x).‣Added the ability to automatically reset MXNet and PyTorch Python iterators.‣Enhanced the Video reader to link dynamically with the CUDA Driver API and nvcuvid.‣Added the ability to deliver exactly 1 epoch from DALIGenericIterator (PyTorch and MXNet).Breaking API Changes‣PyTorch iterator returns the exact number of samples per epoch, so the final batch could be smaller if epoch size is not divisible by the batch size. To keep the oldbehaviour when data is wrapped up, use stop_at_epoch argument.DALI Release 0.6.1 BetaUsing DALI 0.6.1 BetaThe 19.01 NVIDIA GPU Cloud (NGC) optimized container for MXNet, PyTorch, and TensorFlow includes an older version of DALI.To upgrade to DALI 0.6.1 beta, follow the installation instructions in the DALI Quick Start Guide.Refer to the DALI Developer Guide for usage details.Known Issues‣The New Video reader operator requires NVIDIA VIDEO CODEC SDK support in the platform.

NVIDIA BlueField DPU Scalable FunctionUser GuideTable of ContentsChapter 1. Introduction (1)Chapter 2. Prerequisites (3)Chapter 3. SF Configuration (4)3.1. Configuration Using mlxdevm Tool (4)Chapter 1.IntroductionScalable functions (SFs), or sub-functions, are very similar to virtual functions (VFs) which are part of a Single Root I/O Virtualization (SR-IOV) solution. I/O virtualizationis one of the key features used in data centers today. It improves the performance of enterprise servers by giving virtual machines direct access to hardware I/O devices. The SR-IOV specification allows one PCI Express (PCIe) device to present itself to the host as multiple distinct "virtual" devices. This is done with a new PCIe capability structure added to a traditional PCIe function (i.e., a physical function or PF).The PF provides control over the creation and allocation of new VFs. VFs share the device's underlying hardware and PCIe. A key feature of the SR-IOV specification is that VFs are very lightweight so that many of them can be implemented in a single device.To utilize the capabilities of VF in the BlueField, SFs are used. SFs allow support for a larger number of functions than VFs, and more importantly, they allow running multiple services concurrently on the DPU.An SF is a lightweight function which has a parent PCIe function on which it is deployed. The SF, therefore, has access to the capabilities and resources of its parent PCIe function and has its own function capabilities and its own resources. This means that an SF would also have its own dedicated queues (i.e., txq, rxq).SFs co-exist with PCIe SR-IOV virtual functions (on the host) but also do not require enabling PCIe SR-IOV.SFs support E-Switch representation offload like existing PF and VF representors. An SF shares PCIe-level resources with other SFs and/or with its parent PCIe function.IntroductionChapter 2.PrerequisitesPlease refer to the NVIDIA DOCA Installation Guide for Linux for details on how to install BlueField related software.‣Make sure your firmware version is 20.30.1004 or higher‣To enable SF support on the device, change the PCIe address for each port: $ mlxconfig -d 0000:03:00.0 s PF_BAR2_ENABLE=0 PER_PF_NUM_SF=1 PF_TOTAL_SF=236 PF_SF_BAR_SIZE=10PF_BAR2_ENABLE: if this config is set, then all PFs and ECPFs have the samenumber of SFs. This should be off (deprecated).If set. PF_TOTAL_SF and PF_SF_BAR_SIZE won’t work.PER_PF_NUM_SF: If this config is set, each PF and ECPF configure/control its own number of SFs.THE ABOVE TWO CONFIGS AFFECS BOTH BF AND HOST, TREAT WITH CARE!Also, only one of them can be set. It is INVALID to set them bothPF_TOTAL_SF: maximum number of SFs we wish to configure for the given PF/ECPF.PF_SF_BAR_SIZE: size of each SF at the BAR2. The size is in powers of 2 in KB.For example: PF_SF_BAR_SIZE=10 means each SF is taking 1MB of the BAR.PF_TOTAL_SF=14 means this PCI function can create up to 14 SFs.In total: FW will allocate 14MB of BAR2.A cold reboot is needed for the effect to take place.Chapter 3.SF ConfigurationTo use a subfunction, a 3-step setup sequence must be followed first:1.Create.2.Configure.3.Deploy.These steps can be performed using mlxdevm tool.3.1. Configuration Using mlxdevm Tool 1.Create the SF.SFs are managed using the mlxdevm tool supplied with iproute2 package. The tool is found at /opt/mellanox/iproute2/sbin/mlxdevm.An SF is created using the mlxdevm tool. The SF is created by adding a port of "pcisf"flavor.To create an SF port representor, run:/opt/mellanox/iproute2/sbin/mlxdevm port add pci/<pci_address> flavour pcisf pfnum <corresponding pfnum> sfnum <sfnum>Note: Each SF must have a unique number (<sfnum>).For example:/opt/mellanox/iproute2/sbin/mlxdevm port add pci/0000:03:00.0 flavour pcisf pfnum0 sfnum 4Output example:pci/0000:30:00.0/229409: type eth netdev eth0 flavour pcisf controller 0 pfnum 0 sfnum 4function:hw_addr 00:00:00:00:00:00 state inactive opstate detached roce true max_uc_macs 128 trust offThe highlighted number (229409) is required to complete the following two steps (i.e., configuration and deployment).pci/0000:03:00.0/229409 is called the SF index.pci/<pci_address>/<sf_index> can be replaced with <representor_name>. Forexample:pci/0000:03:00.0/229409 = en3f0pf0sf4To see information about the created SF such as its MAC address, trust mode, or state (active/inactive), run the following command:/opt/mellanox/iproute2/sbin/mlxdevm port showOutput example:pci/0000:30:00.0/229409: type eth netdev en3f0pf0sf4 eth0 flavour pcisfcontroller 0 pfnum 0 sfnum 4function:hw_addr 00:00:00:00:00:00 state inactive opstate detached roce truemax_uc_macs 128 trust off2.Configure the SF.A subfunction representor (SF port representor) is created but it is not deployed yet.Users should configure the hardware address (e.g., MAC address), set trust mode to on, and activate the SF before deploying it.The following 3 steps can be executed as separate commands (at any order) orcombined as one:‣To configure the hardware address, run:/opt/mellanox/iproute2/sbin/mlxdevm port function set pci/<pci_address>/<sf_index> hw_addr <MAC address>‣To set the trust mode to on, run:/opt/mellanox/iproute2/sbin/mlxdevm port function set pci/<pci_address>/<sf_index> trust on‣To activate the created SF, run:/opt/mellanox/iproute2/sbin/mlxdevm port function set pci/<pci_address>/<sf_index> state activeAlternatively, to configure the MAC address, set trust mode on, and set the state as active, run:/opt/mellanox/iproute2/sbin/mlxdevm port function set pci/<pci_address>/<sf_index> hw_addr <MAC address> trust on state activeFor example:/opt/mellanox/iproute2/sbin/mlxdevm port function set pci/0000:03:00.0/229409 hw_addr 00:00:00:00:04:0 trust on state activeNote: The SF capabilities above must be set before deploying the SF.3.Deploy the SF.To unbind the SF from the default config driver and bind the actual SF driver, run: echo mlx5_core.sf.<next_serial> > /sys/bus/auxiliary/drivers/mlx5_core.sf_cfg/ unbindecho mlx5_core.sf.<next_serial> > /sys/bus/auxiliary/drivers/mlx5_core.sf/bindFor example:echo mlx5_core.sf.4 > /sys/bus/auxiliary/drivers/mlx5_core.sf_cfg/unbindecho mlx5_core.sf.4 > /sys/bus/auxiliary/drivers/mlx5_core.sf/bindNote: <next_serial> is a number produced by the firmware when creating the SF (thisis the gvmi number of the SF). To obtain it, refer to the useful commands providedbelow.Useful commands:‣To see the available sub-functions, run:$ devlink dev showFor example, if you run the command before creating, configuring, and deploying the SF (using the steps detailed earlier), the output would appear as follows:pci/0000:03:00.0pci/0000:03:00.1auxiliary/mlx5_core.sf.2auxiliary/mlx5_core.sf.3After creating, configuring, and deploying the SF, the output would be:pci/0000:03:00.0pci/0000:03:00.1auxiliary/mlx5_core.sf.2auxiliary/mlx5_core.sf.3auxiliary/mlx5_core.sf.4Note that the <next_serial> number is 4 for the created SF.‣To see the sfnum of each sub-function, run:cat /sys/bus/auxiliary/devices/mlx5_core.sf.<next_serial>/sfnumFor example:cat /sys/bus/auxiliary/devices/mlx5_core.sf.4/sfnumExample output:cat /sys/bus/auxiliary/devices/mlx5_core.sf.4/sfnum4‣To remove an SF, you must first make its state inactive and only then remove the SF representor.To make the SF's state inactive, run:/opt/mellanox/iproute2/sbin/mlxdevm port function set pci/<pci_address>/<sf_index> state inactiveTo delete the SF port representor, run:/opt/mellanox/iproute2/sbin/mlxdevm port del pci/<pci_address>/<sf_index>For example:/opt/mellanox/iproute2/sbin/mlxdevm port function set pci/0000:03:00.0/229409 state inactive/opt/mellanox/iproute2/sbin/mlxdevm port del pci/0000:03:00.0/229409e the SF.Running the application on the DPU requires OVS configuration. By creating SFs, an SF representor for the OVS is also created and named en3f0pf*sf*. Therefore, each representor needs to be connected to the correct OVS bridge.Note: Two SFs related to the same PCIe are necessary for the configuration in theillustration.The following example configures 2 SFs and adds their representors to the OVS.a).Create, configure, and deploy the SFs. Run:/opt/mellanox/iproute2/sbin/mlxdevm port add pci/0000:03:00.0 flavour pcisf pfnum 0 sfnum 4/opt/mellanox/iproute2/sbin/mlxdevm port add pci/0000:03:00.0 flavour pcisf pfnum 0 sfnum 5Using the command mlxdevm port show, you can see the SF indices of thecreated SFs./opt/mellanox/iproute2/sbin/mlxdevm port showOutput example:pci/0000:30:00.0/229409: type eth netdev en3f0pf0sf4 flavour pcisf controller0 pfnum 0 sfnum 4function:hw_addr 00:00:00:00:00:00 state inactive opstate detached roce truemax_uc_macs 128 trust offpci/0000:30:00.0/229410: type eth netdev en3f0pf0sf5 flavour pcisf controller0 pfnum 0 sfnum 5function:hw_addr 00:00:00:00:00:00 state inactive opstate detached roce truemax_uc_macs 128 trust offb).Configure the MAC address, set trust mode on, and activate the created SFs:/opt/mellanox/iproute2/sbin/mlxdevm port function set pci/0000:03:00.0/229409 hw_addr 02:25:f2:8d:a2:4c trust on state active/opt/mellanox/iproute2/sbin/mlxdevm port function set pci/0000:03:00.0/229410 hw_addr 02:25:f2:8d:a2:5c trust on state activeUsing ifconfig, you may see that there are 2 added network interfaces:en3f0pf0sf4 and en3f0pf0sf5 for the two respective SF port representors.c).Delete existing OVS bridges (optional).For example, run the following command to delete an OVS bridge called "ovsbr1": ovs-vsctl del-br ovsbr1d).Create two bridges sf_bridge1 and sf_bridge2 and configure them as follows:ovs-vsctl add-br sf_bridge1ovs-vsctl add-br sf_bridge2ovs-vsctl add-port sf_bridge1 p0ovs-vsctl add-port sf_bridge2 pf0hpfThe OVS bridges after adding the SF representors:Bridge sf_bridge1Port p0Interface p0Port sf_bridge1Interface sf_bridge1type: internalPort en3f0pf0sf4Interface en3f0pf0sf4Bridge sf_bridge2Port sf_bridge2Interface sf_bridge2type: internalPort en3f0pf0sf5Interface en3f0pf0sf5Port pf0hpfInterface pf0hpfSF ConfigurationNVIDIA BlueField DPU Scalable Function MLNX-15-060491 _v2.2.0 | 9ovs_version: "2.14.1"Note: The interface might be down by default. Remember to ifconfing the interfaceto "up" status.Note: When deleting the SF port representor, you must also de-attach it from the bridge it is connected to using the command ovs-vsctl port-del en3f0pf0sf*.Otherwise, the port representor will still be connected to the bridge but would not be recognizable.To run the application, use the following command to initialize the subfunctions during runtime:*Executable_binary* -a auxiliary:mlx5_core.sf.* -a auxiliary:mlx5_core.sf.* For example:doca_application_recognition -a 0000:03:00.0,class=regex -a auxiliary:mlx5_core.sf.4,sft_en=1 -a auxiliary:mlx5_core.sf.5,sft_en=1 -- [application_flags]NoticeThis document is provided for information purposes only and shall not be regarded as a warranty of a certain functionality, condition, or quality of a product.

比特币-类二买回抽均线公式及导入步骤

比特币-类二买回抽均线公式及导入步骤

比特币-类二买回抽均线公式及导入步骤比特币-类二买回抽均线是一种技术分析工具,用于观察比特币价格的波动情况并辅助交易决策。

本文将介绍该均线的计算公式以及如何导入使用。

均线计算公式类二买回抽均线是基于收盘价进行计算的。

具体计算公式如下:1. 首先,选择需要观察的周期。

常见的周期有5日、10日和20日。

以10日为例。

2. 获取最近10个交易日的比特币收盘价,记为P1, P2, P3, ...,P10。

3. 计算这10个收盘价的平均值,即:(P1 + P2 + P3 + ... + P10) / 10。

这个平均值就是类二买回抽均线的值。

导入步骤以下是使用Python编程语言导入类二买回抽均线的步骤:1. 确保已经安装好Python编程环境,并安装好所需的依赖库(如pandas和numpy)。

2. 创建一个新的Python文件。

3. 导入所需的库:import pandas as pdimport numpy as np5. 将获取的价格数据存储为一个pandas的DataFrame对象,确保包含日期和收盘价两列。

6. 使用numpy和pandas库计算类二买回抽均线的值:假设df是包含价格数据的DataFrame对象n = 10 # 周期为10df['EMA'] = df['close'].rolling(window=n).mean()7. 执行以上步骤后,DataFrame对象的'EMA'列将包含类二买回抽均线的值。

以上就是比特币-类二买回抽均线的计算公式及导入步骤。

通过对比特币价格的均线进行观察,可以辅助判断市场走势并做出相应的交易决策。

地址簿功能
本地存储器和所连接手机 / 所插入 SIM 卡中的地址簿条目有所区别。尽管如此仍会一同显示。为了区分,会用相应的图标表示。 个人档案 用户可以针对每部所连接的手机创建最多 4 份个人档案,每份档案最多可存储 2000 个联系人。会针对每部新连接的手机或每张所插入的 SIM 卡自动创建档案。每个联系人最多可以存储 5 个电 话号码(如手机号码、座机号码、工作号码等)。手机图标表示数据存储在手机地址簿中,SIM 卡图标则表示数据存储在 SIM 卡上。 必须注意,地址簿的总容量为最多可存储 5000 个条目。一旦达到 5000 个条目,则无法再导入其他条目。 如果是插入 SIM 卡 (4),受 SIM 卡存储容量所限,可以存储的联系人数量也有限(SIM 卡的标准存储容量是最多可存储 250 个联系人)。 本地存储器的每份档案的容积分别为 100 个地址簿条目。本地存储器中的条目会用汽车图标表示。本地存储器中的每个条目均可以标记是私人还是工作号码,以便搜索。 个人档案的优点是,用户的本地存储器中的条目具有访问保护。本地存储器中的个人档案条目仅供所连接的相应手机或所插入的 SIM 卡 (4) 使用。此外,一旦重新建立连接,这些地址簿条目又 立即可用。 每次重新连接手机和车辆时,都会在后台自动加载手机最新条目到车上。手机上不再存在的条目也会从个人档案中删除。 手机与个人档案的分配是通过手机蓝牙识别(蓝芽 ID)完成的(如果奥迪蓝牙车载电话的 SIM 卡读卡器中插入了 SIM 卡,则会根据 SIM 卡号来分配个人档案)。 一般档案 如果既未连接手机也未插入 SIM 卡,则最多可存储 100 个本地联系人的一般档案可用。 图 一般说明 在“存储容量”菜单中可以读取地址簿条目总数及其所属的现有档案(见图)。 示例: 图 Nokia 6700 classic 的联系人 个人档案 1: 当前连接的手机中的条目: 61 / 2000 本地存储器中的条目(当前连接的手机): 1 / 100 共享联系人 一般档案: 本地存储器中的条目: 4 / 100 图 Weber's iPhone 个人档案 4: 手机中的条目: 398 / 2000 奥迪 MMI 1001 个人档案 3: 所插入的 SIM 卡中的条目: 6 / 2000 Tobias 6230i 个人档案 2: 手机中的条目: 130 / 2000 Nokia 6700 classic 个人档案 1: 手机中的条目: 61 / 2000 总存储器 总存储器一览: 所有档案中的条目: 595 / 5000 (2) “自动”: 在静止状态下打开点火开关约 3-5 分钟后,车载蓝牙可见。一旦超过车速阈值,可见性会切换为“关闭”。 (3) “开启”: 在打开点火开关后车载蓝牙始终可见。 (4) 插入到 J794 或选装听筒的 SIM 卡读卡器中(蓝牙车载电话) (5) 如果在奥迪蓝牙车载电话的 SIM 卡读卡器中插入了一张 SIM 卡,则会根据 SIM 卡号分配个人档案。 (6) 如果在奥迪蓝牙车载电话的 SIM 卡读卡器中插入了一张 SIM 卡,则条目的最大数量取决于 SIM 卡的存储容量。目前常用的 SIM 卡的最大容量为最多可存储 250 个条目,每个条目分别可存 储两个号码。
