MPI Tutorials

You need to have Intel compilers in your environment to run these examples:

setpkgs -a intel_cluster_studio_compiler

Running within SLURM

SLURM has its own MPI job management command called srun, which you can think of as mpirun. With srun you do not need to specify the number of processes you would like to launch, SLURM just launches the program with the maximum allowed process for your job allocation (which is specified in the script that you submit to SLURM).

Order of running:

1. hello/
2. point_to_point/
3. trapezoid/
4. collective/
   • bcast/
   • scatter/
   • scatterv/
   • scatter_gather/
   • reduce/
5. derived_data_types/
