Fortran 和 MPI 的良好分析器 [英] Good profiler for Fortran and MPI

问题描述

对于包含 MPI 的 Fortran 代码库，您使用哪个分析器?gprof 似乎无法正常工作.Sun Studio Analyzer 仅返回 C/C++ 系统调用的计时，并且不显示任何 fortran 函数.

Which profiler do you use for Fortran code base with MPI in it? gprof doesn't seem to be working correctly. Sun Studio Analyzer only returns the timings for the C/C++ system calls and none of the fortran functions appear.

推荐答案

有许多专门用于并行/MPI 程序的性能分析工具，例如:

There are a number of performance analysis tools specialized for Parallel/MPI Programs, such as:

• Score-P，适用于多种不同的分析工具，例如Cube, 吸血鬼
• HPCToolkit 仅使用采样，因此您不必重新编译应用程序
• Tau

• Score-P, which works with a number of different Analysis tools, e.g. Cube, Vampir
• HPCToolkit uses sampling only, so you do not have to recompile your application
• Tau

起初它们可能没有那么简单易用，但它们为研究并行应用程序的性能提供了更多帮助.

At first they may not be as simple to use simple to use, but they provide much more help to investigate the performance of parallel applications.
