An MPI Implementation for Parallel Computing
OpenMPI requires an environment module
In order to use OpenMPI, you must first load the appropriate environment module:
module load intel openmpi
OpenMPI is one of several implementations of the Message Passing Interface (MPI) model of parallel computing for distributed systems. OpenMPI is an open-source implementation of this model with a wide range of powerful features.
Using OpenMPI on RCC resources#
OpenMPI is no longer available for the PGI (now NVIDIA) compilers. If you need to use OpenMPI with the PGI libraries, please let us know.
There are two different implementations of OpenMPI available on the HPC. One is compiled for Intel and the other for GNU GCC:
Running OpenMPI programs#
Regardless of which platform compiler your MPI program executes on, the syntax is the same:
This would typically go in a Slurm submit script.
