PerfHUD 5 快速教程说明书

Chapter 1.Quick TutorialOverviewThis chapter presents a short PerfHUD 5 tutorial to quickly introduce you to severalconvenient and powerful new features. Even if you’ve used previous versions ofPerfHUD, we highly recommend that you read through this tutorial because somuch is new in PerfHUD 5.Launching PerfHUDBy default, the PerfHUD installer will place a shortcut to the PerfHUD Launcheron your desktop. To analyze an application, simply drag its icon onto the PerfHUDlauncher. Keep in mind that the application needs to opt-in for PerfHUD analysis,to prevent unauthorized parties from analyzing your application.Let’s analyze the sample DirectX 10 application that ships with PerfHUD, Sparkles.(This sample is taken from the NVIDIA Direct3D 10 SDK, and includes the opt-inmodification.) For this particular application, you can use the “Sparkles Sample”shortcut in the PerfHUD group in the Start menu.If this is the first time you’re running PerfHUD, you’ll see a configuration dialogbox. The main thing you have to do here is to choose a shortcut key. Pick Ctrl+Z.Once you click OK, Sparkles will start, and PerfHUD will be running on it, asshown below.Note that any keyboard or mouse input will still go the Sparkles application, and notto PerfHUD, until you activate PerfHUD using your hotkey (Ctrl+Z). PerfHUDreminds you of your hotkey with a message at the bottom of the screen: “PressCtrl+Z to activate PerfHUD”.Before activating PerfHUD, press F9 and F10 to hide the user interface of Sparkles,reducing clutter. (Remember, these are hotkeys of Sparkles – once PerfHUD isactive, F9 and F10 will perform different functions.)Activating PerfHUDActivate PerfHUD by pressing Ctrl+Z. You’ll see the status line at the bottom ofthe screen change to four buttons, one for each mode of PerfHUD:between PerfHUD and your application at any time. For example, you may want tonavigate to a different part of the scene to analyze it, and then re-enable PerfHUDwhen you’re done.Help ScreenAt any time while you’re running PerfHUD, you can press F1 to view the Helpwindow. This window also has options for getting System Information as well assetting various PerfHUD options.Performance DashboardPerfHUD starts in the Performance Dashboard. This mode displays many usefuldata values, such as per-unit GPU utilization, driver time, memory usage, and more.New in PerfHUD 5 is the ability to completely customize the PerformanceDashboard’s layout.Creating a New Batch Size GraphLet’s start by creating a new Batch Size graph. This graph displays batches andsizes, allowing you to easily understand the batching characteristics of yourapplication.To add a new graph, right-click on the background and choose New Batch SizeGraph.A new Batch Size graph will now appear with its default settings:Every graph in the Performance Dashboard is customizable. To do this, simplyhover your mouse anywhere on the graph. You’ll see three boxes appear: blue andred boxes at the upper right of the graph, and a green box on the lower right:Clicking on the blue box brings up a configuration dialog.Clicking on the red box closes the current graph.Clicking and dragging on the green box resizes the current graph.Let’s customize the Batch Size Graph. First, resize it using the green box. Thenclick on the blue box and you’ll see the Graph Configuration Dialog.Set the Maximum Batch Size to 100. Then click OK. The graph will now showmore bars.Adding SignalsThe most common type of graph in PerfHUD is the GPU/Driver Graph. EachGPU/Driver graph can display up to 4 signals simultaneously. PerfHUD 5 allowsyou to choose from a huge list of both GPU and driver signals, allowing you tomonitor virtually any aspect of your application’s graphics performance.Let’s add some signals to the GPU/Driver graph that displays the DrawPrimitiveCount and Average Batch by default. To do this, hover over the graph and click onthe blue square at the upper-right of the graph. A Graph Configuration Dialog willpop up:Here, you can choose any signal you want for each line color, as well as descriptionsfor each. You can also decide whether you want to graph the raw signal or apercentage.Choose D3D FPS for the blue line, and name it “FPS”.Choose D3D vidmem MB for the yellow line, and name it “D3D Vid Mem (MB)”Speeding Up and Slowing Down TimeBy pressing the + and – keys, you can scale the passing of time from 6x faster thannormal down to 1/8 speed. Pressing the – key again when at 1/8 speed will freezetime completely. Controlling time is helpful when you want to find a particularlytroublesome set of frames.Running ExperimentsYou can also perform various useful experiments from the Performance Dashboard.These are listed below along with their respective keyboard shortcuts.Use 2x2 Textures Ctrl+TSet NULL Viewport Ctrl+VWireframe Ctrl+WIgnore Draw Calls Ctrl+NColor Fixed Function Shaders Red Ctrl+1Color ps_1_1 Shaders Light Green Ctrl+2Color ps_1_3 Shaders Green Ctrl+3Color ps_1_4 Shaders Yellow Ctrl+4Color ps_2_0 Shaders Light blue Ctrl+5Color ps_2_a Shaders Blue Ctrl+6Color ps_3_0 Shaders Orange Ctrl+7Color ps_4_0 Shaders Red Ctrl+8Using the Frame DebuggerThe Performance Dashboard is most useful for finding a troublesome spot in yourscene. Once you’ve found that spot, you will often want to freeze the frame, debugits draw calls, and analyze its performance in detail.Press F7 to switch to the Frame Debugger. The Frame Debugger will show youjust the first draw call in the scene, which in this case is the skybox:Click and drag the slider at the bottom of the screen from side to side.You’ll see how the frame builds up with various draw calls.The current draw call is highlighted with an orange wireframe.You can use the up and down arrow keys to decrement or increment the currentdraw call. Home jumps to the first draw call, and End jumps to the last draw call.Page Up and Page Down decrement or increment the current draw call by largeramounts.Drag the slider to draw call 2. You should see the cat highlighted in orangewireframe.Viewing Textures and Render TargetsAll the textures used by the current draw call are shown in the Textures panel on theleft of the screen. Click on the Textures panel (to get focus) and press + twiceto enlarge the textures. (Pressing - will reduce the textures.) Note that if you hoverover a texture, a tooltip will appear showing u-v coordinates and RGBA colorinformation.On the right is the list of Render Targets. You can perform the same operations inthat panel as in the Textures panel.Changing the Viewing ModeIn addition to viewing the Frame Buffer as usual, you can also view Wireframe,Depth Complexity, and Depth Buffer renderings for the current frame bychoosing options from the drop-down. These views are shown below.WireframeDepth ComplexityFrame BufferUsing the Advanced State InspectorsTo analyze a particular draw call in depth, you can use PerfHUD’s Advanced StateInspectors. Access these by clicking on the Advanced… button at the lower-rightof the screen.The Vertex Assembly State InspectorYou’ll first see the Vertex Assembly State Inspector. Here you can see the geometryused in the current draw call. You can click and drag the mouse on the geometry torotate it. You can also view details about the geometry in the panel on the right.Next, switch to the Vertex Shader state inspector by clicking on the red VertexShader block at the top of the screen.Vertex Shader State InspectorThe Vertex Shader State Inspector shows you any vertex shader code from thecurrent draw call, as well as any textures and shader constants that are used. In thiscase, there are no textures, so the panel at the left of the screen is blank. You canalso edit the shader in real-time (we’ll cover that when we look at the pixel shader).Click on the purple Geometry Shader block at the top of the screen.Geometry Shader State InspectorThis state inspector is similar to the Vertex Shader state inspector, showing anygeometry shader code, textures, and constants.Click on the green Pixel Shader block at the top of the screen.Pixel Shader State InspectorThe Pixel Shader state inspector is similar to the Vertex Shader and GeometryShader state inspectors, showing any geometry shader code, textures, and constants.The search field (shown in green above) allows you to quickly find a particular textstring. Type paintamp into the search field and press Enter. The shader editorwill jump to the first occurrence of paintamp.Now, replace paintamp with 0.5. Then right-click in the editing area and chooseCompile from the context menu. (You can also save and load your shaders usingthe context menu.)Your modified shader is now used by the application. Press F2 to hide PerfHUD’suser interface, so you can see the modified rendering.Revert the shader to its original form by right-clicking in the editing area andchoosing Revert to Original Shader.Next, click on the blue Raster Operations block at the top of the screen. Raster Operations State InspectorThe Raster Operations state inspector allows you to view and manipulate numeroususeful render states. Any changes you make here affect all draw calls in the scene.(Future versions of PerfHUD will allow you to affect draw calls grouped by statebuckets.)Select the first dropdown (for the Fillmode) and change it to Wireframe. Yourscreen should now look like this:Now right-click on that same drop-down and select Restore All States from theresulting context menu. Note that you can restore states by category if you want to.Frame ProfilerPress F8 to enter the Frame Profiler. You’ll see PerfHUD quickly run a series oftests on the current frame, giving you detailed statistics about draw call performanceand GPU usage. This is one of the uniquely powerful features of PerfHUD –complete bottleneck analysis with just one key press.The Frame Profiler offers several different visualizations, which are listed andexplained briefly below.Unit Utilization Bars. Shows how long each GPU unit was used for the selected draw call, state bucket, and frame. You can define state bucket groupings using the checkboxes at the top of the screen.Unit Bottleneck Bars. Shows how long each GPU unit was the bottleneck for the selected draw call, state bucket, and frame.

performance evaluation理工英语4 Performance EvaluationIntroductionPerformance evaluation is a crucial process in assessing the effectiveness and efficiency of individuals, teams, or organizations. It involves the systematic assessment and measurement of performance against predetermined goals, objectives, and standards. This article aims to explore the concept of performance evaluation, its significance in various contexts, and the different methods used for evaluation.Defining Performance EvaluationPerformance evaluation is defined as the systematic process of assessing and reviewing an individual's or organization's performance in relation to established goals and objectives. It involves analyzing the quality, quantity, and timeliness of work, as well as the overall contribution towards achieving desired outcomes.Significance of Performance EvaluationPerformance evaluation plays a critical role in various contexts, including:1. Employee Performance Evaluation: In organizations, performance evaluation helps assess employees' job performance, identify areas for improvement, and determine reward and promotion opportunities. It provides valuable feedback and helps create a performance-driven culture.2. Team Performance Evaluation: Evaluating team performance is essential for identifying strengths and weaknesses, enhancing collaboration, and optimizing resources. It enables organizations to allocate tasks effectively, promote teamwork, and achieve collective goals.3. Organizational Performance Evaluation: Assessing the overall performance of an organization is essential for strategic planning, decision-making, and performance improvement. It helps identify areas requiring attention and enables organizations to align their objectives with key performance indicators (KPIs).Methods of Performance EvaluationThere are several methods used for performance evaluation, depending on the nature and context of evaluation:1. Rating Scales: This method involves using predefined scales to rate employees' performance against specific criteria. It provides a structured approach and simplifies the evaluation process. However, it can be subjective and may not capture the full extent of performance.2. 360-Degree Feedback: This method involves obtaining feedback from multiple sources, including supervisors, subordinates, peers, and customers. It provides a holistic view of an individual's performance and promotes a comprehensive understanding of strengths and areas for improvement.3. Objective Measurements: Objective measurements involve quantifying performance based on quantifiable data, such as sales figures, production output, or customer satisfaction ratings. This method provides a precise assessment of performance but may not capture qualitative aspects.4. Self-Assessment: Self-assessment encourages individuals to reflect on their performance and identify areas for improvement. It promotes self-awareness, accountability, and personal development. However, it may be biased and influenced by individuals' perceptions.5. Behavioral Observation: This method involves directly observing individuals' behavior in specific work-related situations. It provides valuable insights into work habits, interpersonal skills, and adherence to organizational values. However, it can be time-consuming and may not capture performance in all areas.ConclusionPerformance evaluation is a vital process for assessing and improving individual, team, and organizational performance. It helps organizations align their objectives, motivate employees, and ensure efficient resource allocation.

Missing-Subject Fragments
When a second sentence is written, writers sometimes attempt to leave out the subject. Although the reader may be able to follow the author’s meaning, the sentence is still a fragment.
Examples: • Alicia loved getting wedding presents. But hated writing thank-you notes. • Mickey has orange soda and potato ships for breakfast. Then eats more junk food, like root beer and cookies, for lunch.
Semicolon
Sometimes referred to as a “strong comma,” a semicolon can be used to mark the break between two thoughts. The semicolon can be used alone or with a transitional word.
Examples of Added-detail Fragments
• Before a race, I eat starchy foods. Such as bread and spaghetti. The carbohydrates provide quick energy. • Bob is taking a night course in auto mechanics. Also, one in plumbing. He wants to save money on household repairs. • My son keeps several pets in his room. Including hamsters and mice.

托福听力TPO12真题分类之环境科学

托福听力TPO12真题分类之环境科学托福听力考试贯穿于整个考试中，很多题目都涉及听力，所以建议同学们要重视托福词汇的记忆，下面是小编给同学们带来的托福听力TPO12分类之环境科学，跟着小编的脚步一起来认真分析一下吧!托福听力TPO12分类之环境科学Lecture 4 (environmental science)NarratorListen to part of a lecture in an environmental science class.ProfessorAll right folks, let's continue our discussion of alternative energy sources and move on to what's probably the most well-known alternative energy source - solar energy. The sun basically provides earth with a virtually unlimited source of energy every day, but the problem has always been how do we tap this source of energy.Can anyone think of why it's so difficult to make use of solar energy?Female studentBecause it’s hard to…um… gather it?ProfessorThat's exACTly it. Solar energy is everywhere, but it's also quite diffused. And the thing is the dream of solar energy is not a new one. Humanity has been trying to use the sun's light as a reliable source of energy for centuries. And around the beginning of the 20th century there were ACTually some primitive solar water heaters on the consumer market. But they didn't sell very well. Any of you wanna guess why?Female studentWell, there were other energy choices like oil and natural gas,right?ProfessorYeah, and for better or for worse, we chose to go down that path as a society. When you consider economic fACT ors, it's easy to see why. But then in the 1970s, there was an interest in solar energy again. Why do you think that happened?Male studentBecause oil and natural gas were...er...became scarce?ProfessorWell, not exACTly. The amount of oil and natural gas in the earth was still plentiful, but there were other reasons. It's a political thing really and I'm gonna get into that now. So what happened in the 1970s was oil and natural gas became very expensive very quickly, and that spurred people to start looking into alternative forms of energy, solar energy probably being the most popular. But then in the 80s, this trend reversed itself when the price of oil and natural gas went down. All right. Let's shift our focus now to some of the technologies that have been invented to overcome the problem of gathering diffused solar energy. The most basic solution is simply to carefully place windows in a building, so that the sun shines into the building and then it's absorbed and converted into heat. Can anyone think of where this is most commonly used?Female studentGreenhouses.ProfessorYep, greenhouses, where plants are kept warm and provided with sunlight because the walls of the building are made entirely of glass. But we do also have more complex systems that are used for space heating and they fall into two categories: passive andACTive heating systems. Passive systems take advantage of the location or design of a house. For example, solar energy is gathered through large glass panels facing the sun.The heat is then stored in water-filled tanks or concrete. No mechanical devices are used in passive heating systems. They operate with little or no mechanical assistance. With ACTive systems, on the other hand, you collect the solar energy at one location, and then you use pumps and fans to move heat from the collectors through a plumbing system to a tank, where it can be used to heat a home or to just provide hot water.Male studentExcuse me professor, but I've got to ask. How can solar energy work at night or on cloudy days?ProfessorThat's...well...that is a really good question. As a matter of fACT, science is still working on it, trying to find ways of enhancing energy storage techniques so that the coming of night or cloudy days really wouldn't matter.That is the biggest drawback to solar energy - the problem of what do you do in cases where the sun's light is weak or virtually non-present. So the storage of solar energy, lots of solar energy, is a really important aspect.Female studentDoes that mean that solar energy can only be used on a small scale, like heating a home?ProfessorWell ACTually, there have been some attempts to build solar energy power plants. The world's largest solar power plant is located in Kramer Junction California. It can generate 194 megawatts of electric power, but that's just a drop in the bucket.Right now the utility companies are interested in increasing the capacity of the Kramer Junction Plant, but only time will tell if it will ever develop into a major source of power for that region, considering the economic and political fACTors involved.托福听力对话常见词：学术研究1. hypothesis 假说2. hypothesize v.假设3. alternative hypothesis 另一种假说4. null hypothesis 无效假说, 零假说5. collect data 收集信息6. process data 处理信息7. survey 调查8. questionnaire 问卷9. experiment 实验10. interfere(实验)干预11. observation 观察12. analyze data 分析数据13. interpret data 解释数据14. analytical 分析的15. experiment subject 实验对象16. sample 样品17. control group 控制组(被实验的)18. reference group 参照组(未经实验的)19. field research 实地研究托福听力对话常见词：校园工作1. letter of reference/recommendation 推荐信2. competitive 有竞争力的3. benefit future career 对未来职业有帮助4. qualification资格/qualified 合格的5.

formal teaching consists of lectures -回复

formal teaching consists of lectures -回复Formal teaching consists of lectures –an in-depth explorationIntroduction:Formal teaching, often associated with traditional education systems, is characterized by structured classroom settings and lectures delivered by teachers. Lectures have long been a cornerstone of formal teaching methods, allowing educators to impart knowledge and engage students in a systematic manner. In this article, we will delve into the concept of formal teaching through lectures, exploring its benefits, limitations, and potential future developments.I. The role of lectures in formal teaching:Lectures serve as a fundamental tool in formal teaching due to their ability to convey vast amounts of information to a large group of students simultaneously. By presenting comprehensive content and explaining complex concepts, educators can provide a solid foundation for learning. Lectures also allow for the inclusion of visual aids, demonstrations, and real-life examples, enhancing students' understanding of the subject matter.II. Benefits of lectures in formal teaching:1. Structured learning: Lectures provide a structured framework for learning, enabling students to follow a predefined curriculum and progress systematically through the course material. This structure facilitates the development of a strong foundational knowledge base.2. Efficient transfer of information: Lectures allow educators to cover a wide range of content efficiently. Through organized presentations, they can condense information and present it in a concise and organized manner, ensuring that students receive a comprehensive overview of the subject matter.3. Expert guidance: Lectures provide students with direct access to expert knowledge. Skilled educators have the ability to synthesize complex ideas, draw connections, and offer valuable insights, ultimately guiding students towards a deeper understanding of the subject.III. Limitations of lectures in formal teaching:1. Passive learning: Lectures often follow a one-way communication pattern, providing limited opportunities forinteractive engagement. This passive learning experience can hinder students' active participation, critical thinking, and the development of problem-solving skills.2. Information overload: The sheer amount of information presented in lectures can overwhelm some students, making it difficult for them to absorb and retain knowledge effectively. The fast-paced nature of lectures can also inhibit deeper levels of understanding and reflection.3. Individual differences: Lectures cater to a diverse group of learners, each with unique learning preferences and needs. This standardized approach may not effectively accommodate individual learning styles, potentially leaving some students disengaged or struggling to fully grasp the material.IV. Future developments in formal teaching through lectures: While lectures remain a staple in formal teaching, advancements in technology and pedagogy offer opportunities for innovation and improvement. To address the limitations of traditional lectures, teachers can incorporate the following strategies:1. Interactive elements: Utilizing multimedia resources, such as videos, animations, and interactive quizzes, can enhance student involvement and promote active learning during lectures. Incorporating discussions, group activities, andquestion-and-answer sessions can also encourage student engagement.2. Flipped classrooms: This approach involves students reviewing lecture materials before class, allowing class time to be devoted to discussions, problem-solving, and hands-on activities. Flipped classrooms empower students to take an active role in their learning and foster deeper understanding through application.3. Blended learning: Combining traditional lectures with online resources and platforms can offer students a more personalized learning experience. Online modules, virtual simulations, and discussion forums can complement face-to-face lectures, accommodating diverse learning needs and encouragingself-paced learning.Conclusion:Formal teaching consisting of lectures remains a prevalent methodin education systems worldwide. While lectures provide several benefits, such as structured learning and efficient information transfer, they also have limitations, including passive learning and information overload. However, by incorporating innovative strategies such as interactive elements, flipped classrooms, and blended learning, educators can enhance the effectiveness of lectures and create a more engaging and inclusive learning environment. As education continues to evolve, formal teaching through lectures will adapt, leveraging technology and pedagogical advancements to better serve the needs of diverse learners.。
