文件./src/mpid/ch3/include/mpid_rma_shm.h第 592 行断言失败：local_target_rank >= 0 internal ABORT

这是我的来源：

    # include "mpi.h"
    
    int main ( int argc, char *argv[] );
    void pt(int t[], int s);
    
    int main ( int argc, char *argv[] )
    {
        int rank, size, shared_elem = 0, i;
        MPI_Init ( &argc, &argv );
        MPI_Comm_rank ( MPI_COMM_WORLD, &rank );
        MPI_Comm_size ( MPI_COMM_WORLD, &size );
        MPI_Win win;
        int *shared;
        
        if (rank == 0) shared_elem = …
