The required MPI components must be installed to run the MPI-based parallel implementation of Abaqus. MPI, or Message Passing Interface, refers to a middleware used to facilitate interprocessor communication. MPI-based parallelization is available for both computer clusters and shared memory architecture platforms. The necessary MPI software is included with Abaqus and is installed during the Abaqus product installation on most platforms. The latest information on supported platforms, MPI versions, and availability can be found under the System Information section of the Support page at www.simulia.com. For information about configuring and using MPI-based parallelization with Abaqus, refer to the SIMULIA Online Support System, which is available from the My Support page at www.simulia.com.
