Slurm Submit MPI Operations

Slurm Submit MPI Operations first, prepare a MPI program, which uses the Python language's mpi4py library to write a helloworld.py

#!/usr/bin/env python "" "Parallel Hello World" "

mpi4py import MPI
import sys
Time

size = MPI.COMM_WORLD.Get_size ()
rank = MPI.COMM_WORLD.Get_rank ()
name = MPI. Get_processor_name ()

sys.stdout.write ("Hello, world! I am is in process%d of%d on%s.\n "% (rank, size, name)
Time.sleep (300)

Slurm Submit Job Script helloworld.sh

#!/bin/sh

#SBATCH-o/apps/mpi/myjob.out
#SBATCH--nodes=2
#SBATCH--ntasks-per-node=2
mpirun python/apps/mpi/helloworld.py

Slurm Submit MPI Operations
