Usage Examples
Message Passing Interface (MPI) is a standardized and portable message-passing system designed by a group of researchers from academia and industry to function on a wide variety of parallel computing architectures. The standard defines the syntax and semantics of a core of library routines useful to a wide range of users writing portable message-passing programs in C, C++, and Fortran. There are several well-tested and efficient implementations of MPI, many of which are open-source or in the public domain. These fostered the development of a parallel software industry, and encouraged the development of portable and scalable large-scale parallel applications.
Interactive Mode
This example runs on an interactive session.
[username@login01 ~]$ interactive salloc: Granted job allocation 629854 Job ID 629854 connecting to c001, please wait... [username@c001 ~]$ module add openmpi/gcc/8.2.0 [username@c001 ~]$ mpirun -np 20 mpiTEST
Batch Job
This runs on the scheduler SLURM
#!/bin/bash #SBATCH -J MPI-testXX #SBATCH -N 10 #SBATCH --ntasks-per-node 28 #SBATCH -D /home/user1/CODE_SAMPLES/OPENMPI #SBATCH -o %N.%j.%a.out #SBATCH -e %N.%j.%a.err #SBATCH -p compute #SBATCH --exclusive echo $SLURM_JOB_NODELIST module purge module add gcc/8.2.0 module add openmpi/gcc/8.2.0 export I_MPI_DEBUG=5 export I_MPI_FABRICS=shm:tmi export I_MPI_FALLBACK=no mpirun -mca pml cm -mca mtl psm2 /home/user1/CODE_SAMPLES/OPENMPI/scatteravg 100
And passing it to SLURM:
[username@login01 ~]$ sbatch mpidemo.job Submitted batch job 1889552
