工具来检测在C / C ++应用程序错误共享 [英] Tools to detect False Sharing in a C/C++ application

问题描述

是否有检测并用C或C ++应用程序报告伪共享任何工具？

Are there any tools that detect and report False Sharing for applications written in C or C++?

推荐答案

尝试警长和$ P​​ $ pdator。
警长在 https://github.com/plasma-umass/sheriff ，而predator是 https://github.com/plasma-umass/$p$pdator。
predator是，你必须重新编译使用新的LLVM编译器程序编译器为基础的方法。这是最详尽的检测工具到现在。
警长库，但如果你使用pthreads库它只能检测出伪共享。

Try Sheriff and Predator. Sheriff is at https://github.com/plasma-umass/sheriff, while Predator is at https://github.com/plasma-umass/Predator. Predator is a compiler-based approach that you have to recompile your program using a new LLVM compiler. It is the most exhaustive detection tool up to now. Sheriff is library but it can only detect false sharing if you are using pthreads library.
