我的计划：
#include <stdio.h>
#include <mpi.h>
int main(int argc, char *argv[]) {
int numprocs, rank, namelen;
char processor_name[MPI_MAX_PROCESSOR_NAME];
MPI_Init(&argc, &argv);
MPI_Comm_size(MPI_COMM_WORLD, &numprocs);
MPI_Comm_rank(MPI_COMM_WORLD, &rank);
MPI_Get_processor_name(processor_name, &namelen);
printf("Process %d on %s out of %d\n", rank, processor_name, numprocs);
MPI_Finalize();
}
要运行的命令：
mpirun -np 2 -machinefile mach_list a.out
我收到了这些错误：

机器文件的内容是：
noor@192.168.1.4
noor@192.168.1.4没问题，我已经使用没有密码的ssh登录了，因为我已经在那里复制了公钥。
