我的程序如何检测是否通过mpirun启动 [英] How can my program detect, whether it was launch via mpirun

问题描述

我的MPI程序是作为独立应用程序还是通过mpirun启动的，该如何检测?

How can my MPI program detect, if it was launched as a standalone application or via mpirun?

推荐答案

考虑到Semiuseless和Hristo Iliev的回答和评论，没有通用且可移植的方式来做到这一点.解决方法是，您可以检查由mpirun设置的环境变量.参见例如:

Considering the answer and comments by semiuseless and Hristo Iliev, there is no general and portable way to do this. As a workaround, you can check for environment variables that are set by mpirun. See e.g.:
