确定线程的执行时间和不同线程的IO访问

本文介绍了确定线程的执行时间和不同线程的IO访问的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我想确定多线程程序中线程的执行时间，并且我还想了解每个线程进行的IO访问.

I want to determine execution time of a thread in a multi-threaded program, and I also want to know about IO accesses made by each thread.

是否有任何命令/工具可以对C程序执行此操作?

Is there any command/tool which can do this for C programs?

推荐答案

要确定执行情况，您可以尝试 valgrind (特别是callgrind模块).还有一个用于输出的整洁的可视化工具，名为 KCacheGrind

For determining the execution you could try valgrind (specifically the callgrind module). There is also a neat visualization tool for the output called KCacheGrind

要监视IO访问，可以使用 strace .

For monitoring IO access you could use strace.
