问题描述

据我所知，mpirun和mpiexec都是启动器.有人能说出mpiexec和mpirun之间的确切区别吗?

As per my little knowledge mpirun and mpiexec both are launcher. Can anybody tell the exact difference between mpiexec and mpirun?

推荐答案

mpiexec是在MPI标准中定义的(至少是最新版本)，因此我将其引荐给您(您最喜欢的搜索引擎会为它们找到它们)您)获取详细信息.

mpiexec is defined in the MPI standard (well, the recent versions at least) and I refer you to those (your favourite search engine will find them for you) for details.

mpirun是由许多MPI实现实现的命令.但是，它从来没有被标准化过，实现之间总是存在细微的差异.有关详细信息，请参见您选择的实现的文档.

mpirun is a command implemented by many MPI implementations. It has never, however, been standardised and there have always been, often subtle, differences between implementations. For details see the documentation of the implementation(s) of your choice.

是的，它们都是用于启动MPI程序的，这些天mpiexec通常是可取的，因为它已经标准化.

And yes, they are both used to launch MPI programs, these days mpiexec is generally preferable because it is standardised.
