Это относится к MPI с двумя компьютерами с 64-битным процессором и третьим компьютером с 32-битным процессором. Все компьютеры имеют одинаковые точные местоположения для lib и bin, и все они имеют одинаковый bashrc вместе с одной и той же папкой, где хранятся исполняемые файлы. Соединение SSH работает одинаково как для 64-битной, так и для 32-битной машины. Сервер является 64-битной машиной. Я локально скомпилировал исполняемый файл на 32-разрядной машине (обозначается как ([K7ASA: 1555])), и он работал на нем, но когда я попытался запустить его параллельно, я получил это сообщение.
mpirun -host 10.42.0.163,10.42.0.72,10.42.0.68 ./mpi_quad-1
--------------------------------------------------------------------------
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
