OpenMC with MPI from conda

User Support

Hi All,

I would like to use OpenMC with MPI. I have some troubles building from source as I am installing on a cluster and not my own computer.

I was wondering if it was possible to install OpenMC with MPI from conda forge?

Thanks a lot.

Hi Julien,

Right now the package on conda forge is not configured for use with MPI. We may look into having that as an option in the future, but for the time being, you’ll need to build from source if you want to use MPI. I’d be happy to help if you are having trouble building from source on your cluster.

Best regards,
Paul

Hi,
I have seen this message from 2018. Now, is it possible to install openmc with mpi from conda forge?

@angelines Yes, our package on conda-forge now supports MPI:

  • Built against MPICH: conda install "openmc=*=*mpi_mpich*"
  • Built against OpenMPI: conda install "openmc=*=*mpi_openmpi*"
