MPI Library Installation

The MPI library is only necessary if you intend to run AstroBEAR in parallel; otherwise you can get away with skipping this installation.

AstroBEAR was developed using ​LAM-MPI and is compiled using the Intel compiler suite. An alternative, ​MPI-CH exists, but has not been fully tested with AstroBEAR.

We compiled LAM-MPI using version 9.0 of the Intel compilers; anyone using a different version should change references to the 9.0 suite to the appropriate version.

Downloading and installing LAM-MPI
