This is often indicative of a mismatched MPI library and mpiexec launcher. Take care to ensure that the MPI library linked to your binary and mpiexec are (ideally) part of the same installation. Ken On 9/6/19 12:34 AM, Sepinoud Azimi via discuss wrote:

Hi,

I am trying to run a python code on cluster with Mpiexec using the command mpiexec -n 5 python parallel_simulation.py. This is supposed to run on 5 processes (that is what happening on local machine). But on cluster it keeps running it with 1 process. I have tried mpi4py but apparently it has conflict. I was wondering if you have any idea how to fix this.

Many thanks in advance. _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
