[SOLVED] mpi_hostfile configuration on a cluster

Hello,

this time I install code-aster 12.3 parallel on a cluster system. Now I have to configure /opt/aster/etc/codeaster/mpi_hostfile. Which item I have to write for a cluster with 4 (Node) x 24 core per node?

About informations I'm very happy.

Thanks and greeting Markus

Re: [SOLVED] mpi_hostfile configuration on a cluster

Hello,

It depends of the mpirun command you are using.
If it is not necessary, you can just put "localhost" in mpi_hostfile.

This file may be useful to tell mpirun which nodes are allocated.
