MPI не может создать параллельный процесс, происходит сбой в MPI_INIT

/ 04 ноября 2019

Я изучаю интерфейс MPI для C и только что установил MPI для моей системы (Mac Os Mojave 10.14.6). Я сделал это с помощью этого урока . Все было хорошо, и теперь я хотел начать свой первый простой код. Я пытался понять ошибку и искал решение, но не смог найти его самостоятельно. Использование CLion в качестве IDE. main.c 

#include <stdio.h>
#include <mpi.h>

int main(argc, argv)
        int argc;

        char **argv;
{
    int rank, size;
    MPI_Init( &argc, &argv );
    MPI_Comm_size(MPI_COMM_WORLD, &size);
    MPI_Comm_rank(MPI_COMM_WORLD, &size);
    printf("Hi from process %d of $d\n", rank, size);
    MPI_Finalize();
    return 0;
}

It looks like orte_init failed for some reason; your parallel process is
in a path that is too long for the Unix domain socket:
likely to abort.  There are many reasons that a parallel process can
fail during orte_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):
