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果。 传统的lin...
cmake ..make -jsudo ln -sf `realpath tests/benchdnn/benchdnn` /usr/local/bin/ Testing Using Varying SIMD Levels With processwatch and oneDNN/benchdnn configured, we're ready to profile a test workload. In the script below, we focus on a particular convolution kernel, chos...
> python -m timeit -n 5 -r 4 -s "some python code" > 5 loops, best of 1: 8.45 sec per loop 其中,-n 表示每次运行循环次数,-r表示重复次数,-s后面接测试的代码块。 如果用IPython,可以直接用%timeit。 cProfiler 输入如下命令进行Profile,并把结果输出到profile.stats文件。 python -m cProfi...
To be able to view the kernel source you need to compile the code using the -lineinfo option. If this compiler option is not used, only the disassembly view will be shown. This view is displayed for the following types of analysis: Global Memory Access Pattern Analysis Shared Memory Access...

A high number of warps waiting at a barrier is commonly caused by diverging code paths before a barrier. This causes some warps to wait a long time until other warps reach the synchronization point. Whenever possible, try to divide up the work into blocks of uniform workloads. If the block...
The first mechanism is a callback API that allows tools to inject analysis code into the entry and exit point of each CUDA C Runtime (CUDART) and CUDA Driver API function. Using this callback API, tools can monitor an application’s interactions with the CUDA Runtime and driver. The seco...
