a long term geodynamics simulation platform
StGermain-based codes such as Underworld require an implementation of the MPI-1 standard for parallel message-passing, even if you only intend to run the code in serial. Fortunately, there are several free implementations of MPI than run on all flavours of Unix. If you intend to run Underworld on your desktop or a commodity cluster that doesn't yet have an MPI implementation, you could install one of the following free implementations:
- Mpich2 - a portable, open source MPI. Suitable for "all flavours of UNIX", and should be used on macs if you want to use MUMPS, otherwise OpenMPI (see below) is recommended for macs. Further information on MPICH is available here, including documentation and manual pages.
- OpenMPI - recommended for macs. Further information is available here.
You will need to set up environment variables and add your MPI implementation to your path. Click on the links below for instructions on how to do this for MPICH2 and OpenMPI:
