2.3 Installation of MPI libraries for parallel execution on Windows

Benefits: Message Passing Interface (MPI) components required for parallel execution are provided and installed during the Abaqus product installation.

Description: On Windows/x86-64 platforms, the Abaqus product installer automatically installs the Microsoft MPI libraries. On Windows/x86-32 platforms, the Abaqus product installer automatically launches the installer for the Hewlett-Packard HP Message Passing Interface library (HP-MPI).

These libraries are required to use MPI-based parallel execution in Abaqus/Standard, to use domain-level parallelization in Abaqus/Explicit, or to run any job in Abaqus/CFD (regardless of the number of CPUs). If your Abaqus users will be running these types of simulations, you must have the required MPI components preinstalled or allow the Abaqus installer to install them for you.
