当我使用 mpiexec 执行命令时；我遇到了一个始终如一的错误，我找不到任何文档：
mpiexec -H SLAVE1,SLAVE2,SLAVE3 $HOME/bfs/run
Error in msg_queue_server's constructor: File exists
--------------------------------------------------------------------------
Primary job terminated normally, but 1 process returned
a non-zero exit code. Per user-direction, the job has been aborted.
--------------------------------------------------------------------------
--------------------------------------------------------------------------
mpiexec detected that one or more processes exited with non-zero status, thus causing
the job to be terminated. The first process to do so was:
Process name: [[669,1],0]
Exit code: 1
--------------------------------------------------------------------------
有没有人对如何解决这个问题有任何想法？我找不到任何关于面临“文件存在”错误的人的类似问题（甚至提及）。
