我是 Slurm 和 mpi4py 的新用戶，所以我想測試我在這里找到的一些代碼： https: //researchcomputing.princeton.edu/mpi4py我的Python代碼test.py如下：from mpi4py import MPIimport sysdef print_hello(rank, size, name):  msg = "Hello World! I am process {0} of {1} on {2}.\n"  sys.stdout.write(msg.format(rank, size, name))if __name__ == "__main__":  size = MPI.COMM_WORLD.Get_size()  rank = MPI.COMM_WORLD.Get_rank()  name = MPI.Get_processor_name()  print_hello(rank, size, name)我的 bash 腳本是：#!/bin/bash#SBATCH --job-name=mpi4py-test #SBATCH --nodes=1                #SBATCH --ntasks=3              #SBATCH --cpus-per-task=1 srun python test.py運行時sbatch run.sh我期望得到類似的東西：Hello World! I am process 0 of 3 on node1.Hello World! I am process 1 of 3 on node1.Hello World! I am process 2 of 3 on node1.但是我得到：Hello World! I am process 0 of 1 on node1.Hello World! I am process 0 of 1 on node1.Hello World! I am process 0 of 1 on node1.如果我改變的srun python test.py話srun mpiexec -n 3 python test.py我會得到：Hello World! I am process 0 of 3 on node1.Hello World! I am process 2 of 3 on node1.Hello World! I am process 1 of 3 on node1.Hello World! I am process 1 of 3 on node1.Hello World! I am process 0 of 3 on node1.Hello World! I am process 2 of 3 on node1.Hello World! I am process 0 of 3 on node1.Hello World! I am process 1 of 3 on node1.Hello World! I am process 2 of 3 on node1.該進程執行了 3 次，但我只想執行一次。提前致謝。
