无法使用subprocess.Popen启动mpirun

标签： python subprocess mpi pipe

我按照说明here。

会发生什么，wait或communicate立即返回，并且不等待mpi进程完成。我在我的python应用程序中的一个单独的线程中执行此操作。当我在python shell中以交互方式执行此操作时，它似乎有时会起作用。也许我必须在Popen之后和wait / communicate之前等待？

我正在调用Popen，如下所示：

mpicmd = 'mpirun -n 2 --hostfile hostfile ' + executable + ' ' + mpiArgs
mpirun = subprocess.Popen(mpicmd, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True)
out, err = mpirun.communicate()

当我从我的程序中运行mpirun时，我得到：

--------------------------------------------------------------------------
There are no allocated resources for the application 
  rttl
that match the requested mapping:
  hostfile

Verify that you have mapped the allocated resources properly using the 
--host or --hostfile specification.

当我以交互方式（在同一目录中）进行时，它可以正常工作。

也尝试过：

mpirun = subprocess.Popen(['mpirun', '-n', '2', '--hostfile', 'hostfile', 'rttl', '10000'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)

并得到了相同的结果。

我只是遇到了同样的问题。我正在将主机文件的内容写成这样的文件：

      xSh.Select

然后我正在调用MPI命令。问题是我忘记了myfile = open("hostfile", "w") myfile.write("localhost") 命令...在我的MPI命令为我修复该命令之前添加了它。

我知道这是一篇过时的文章，但也许​​有人可能碰到同样的问题
