这适用于MPI，其中2台计算机运行64位cpus，另一台计算机运行32位cpu。所有计算机对于lib和bin具有相同的确切位置，并且它们都具有完全相同的bashrc以及用于存储可执行文件的相同文件夹。 SSH连接在64位计算机和32位计算机上均相同。该服务器是一台64位计算机。我在32位计算机上本地编译了可执行文件（显示为（[K7ASA：1555]）），并且该文件可以运行，但是当我尝试远程并行运行时，收到了此消息。

--------------------------------------------------------------------------
It looks like MPI_INIT failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during MPI_INIT; some of which are due to configuration or environment
problems. This failure appears to be an internal failure; here's some
additional information (which may only be relevant to an Open MPI
developer):
ompi_mpi_init: ompi_rte_init failed
--> Returned "(null)" (-43) instead of "Success" (0)
--------------------------------------------------------------------------
*** An error occurred in MPI_Init
*** on a NULL communicator
*** MPI_ERRORS_ARE_FATAL (processes in this communicator will now abort,
*** and potentially your MPI job)
[K7ASA:1555] Local abort before MPI_INIT completed completed successfully, but am not able to aggregate error messages, and not able to guarantee that all other processes were killed!
-------------------------------------------------------
Primary job terminated normally, but 1 process returned
a non-zero exit code. Per user-direction, the job has been aborted.
-------------------------------------------------------
--------------------------------------------------------------------------
mpirun 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: [[40577,1],2]
Exit code: 1
