>我已经安装了OpenMPI,并尝试编译/执行最新版本提供的示例之一。当我尝试使用 mpiexec 运行时,它说该地址已被使用。
有人得到了提示,为什么这种情况总是发生?

-------------------------------------------------------
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: [[56076,1],0]
Exit code: 1

提前谢谢。
好的。我现在已经用export TMPDIR=/tmp
更改了$TMPDIR环境变量,它可以工作。
现在在我看来,OpenMPI 会话文件夹阻止了我的通信。但为什么呢?我在这里错过了什么吗?
