8. MPI
The following MPIs can be used with the ABCI system.
To use one of these libraries, it is necessary to configure the user environment in advance using the module command.
If you run the module command in an interactive node, environment variables for compilation are set automatically.
If you run the module command in a compute node, environment variables both for compilation and execution are set automatically.
[username@es1 ~]$ module load openmpi/2.1.6
[username@es1 ~]$ module load mvapich/mvapich2-gdr/2.3
[username@es1 ~]$ module load mvapich/mvapich2/2.3
[username@es1 ~]$ module load intel-mpi/2018.2.199
The following is a list MPI versions installed in the ABCI system.
