在我的c ++项目中禁用OpenMP pragma语句 [英] Disabling OpenMP pragma statements everywhere in my c++ project

问题描述

在我的c ++项目中，有几个 #pragma omp parallel for private（i）语句。当我尝试使用valgrind跟踪我的代码中的错误，OpenMP装饰导致可能丢失的内存泄漏消息。我想完全禁用所有上述 #pragma 语句，以便我可以隔离问题。

In my c++ project, there are several #pragma omp parallel for private(i) statements. When I try to track down bugs in my code using valgrind, the OpenMP adornments result in "possibly lost" memory leak messages. I would like to totally disable all of the aforementioned #pragma statements so that I can isolate the problem.

但是，我在我的代码中使用 omp_get_wtime（），我不想禁用这些函数调用。所以我不想完全禁用我的项目中的所有OpenMP功能。

However, I use omp_get_wtime() in my code, and I do not wish to disable these function calls. So I don't want to totally disable all OpenMP functionality in my project.

如何简单地关闭所有 #pragma omp parallel

How can I simply turn off all the #pragma omp parallel for private(i) statements?

我使用Eclipse CDT自动管理makefile，所以我通常在发布模式下编译： make all -C release 。理想情况下，我想要一个解决我的问题，允许我使用一个语句，如 make all -C release -TURN_OFF_PARALLEL 编译，这将导致所有上述 #pragma 语句关闭。

I use Eclipse CDT to automatically manage makefiles, and so I normally compile in release mode by: make all -C release. Ideally, I would like a solution to my problem that permits me to compile using a statement such as make all -C release -TURN_OFF_PARALLEL which would result in all the aforementioned #pragma statements being turned off.

推荐答案

最简单的解决方案是： p>

The simplest solution is to:

1. 禁用OpenMP


2. 链接OpenMP存根库函数

如果您的OpenMP实现不提供存根函数，您可以从标准。

In case your OpenMP implementation doesn't provide stub functions, you can create your own copying from Appendix B of the standard.
