Code Profiling Code Profiling工具是指一个分析使用资源并生成报告的工具,这里的资源指内存,CPU,网络带宽等。 在做调优的第一步是使用工具将程序运行的真实定量数据收集起来,这种数据,就成为profiling data。通过profiling data,我们可以直观地看到资源消耗,并且找出问题所在,同时也可以科学地评估我们为代码性能调优后的结...
代码分析(code profiling)是一种可以使这项任务变得更容易的方法。代码分析包括对那些表示运行系统上的某些处理器活动 … blog.chinaunix.net|基于46个网页 2. 代码剖析 这种行为就称为代码剖析(code profiling)。本文将简要介绍 GNU 编译器工具包所提供的一种剖析工具,它的名字让人可以产 … ...
Two buttons provide Automatic Comparison Selection, so you can compare the data from the workers that took the most versus the least amount of time to execute the code, or data from the workers that spent the most versus the least amount of time in performing interworker communication. Manual...
It shows which code paths are more busy on the CPU in given samples. They can be generated with any OS profiler that contains stack traces such as perf, eBPF, and SystemTap. An example of a flame graph can be found below: Each box is a function in the stack, and wider boxes mean ...
Using PerfTips, you can view performance information while interacting with your code. You can check information such as the duration of the event (measured from when the debugger was last paused, or when the app started). For example, if you step through code (F10, F11), PerfTips show ...
When profiling, you want to collect profile data for the CUDA functions implementing the algorithm, but not for the test harness code that initializes the data or checks the results. The application operates in phases, where a different set of algorithms is active in each phase. When the ...
If you are using the C55x simulator, take advantage of its pipeline conflict detection capabilities. Watch the clock variable when stepping through your code in the C55x simulator to view the intervention of the pipeline protection unit. If the clock increments by more than 1, there...
The .NET Framework namespace System.Diagnostics includes the Trace, Debug, and TraceSource classes for tracing execution flow, and the Process, EventLog, and PerformanceCounter classes for profiling code. The Cordbg.exe command-line debugger can be used to debug managed code from the command-line...
