MPJ-Express is a Java library that provides message passing capabilities for parallel computing in Java applications.

MPJ-Express is available on Oakley.


MPI is a standard library for performing parallel processing using a distributed-memory model. The Glenn and Oakley clusters at OSC use the MVAPICH implementation of the Message Passing Interface (MPI), which is based on MPICH and optimized for the high-speed Infiniband interconnects.

MVAPICH2, based on the MPI-2 standard, is installed on both Oakley and Glenn. The older MVAPICH, based on the MPI-1 standard, is installed on Glenn only.
