OpenMPI at SCS

Description

Open MPI is a project combining technologies and resources from several other projects (FT-MPI, LA-MPI, LAM/MPI, and PACX-MPI) in order to build the best MPI library available. A completely new MPI-2 compliant implementation, Open MPI offers advantages for system and software vendors, application developers and computer science researchers.

General Use

OpenMPI programs must be compiled and linked with the appropriate MPI compiler. The user creates a special environment for jobs to run in.

Cluster Specific Use

Phoenix

* The openmpi root directory for the gcc-compiled version is /usr/local/openmpi/gcc. * The openmpi root directory for the pgi-compiled version is /usr/local/openmpi/pgi. * Use the sge environment openmpi for submitting openmpi jobs.
