MOM requires a Fortran 90 compiler, UNIX, and a C-preprocessor.
MOM was designed to execute most efficiently on vector processors, although it will run reasonably well on scalar processors. It was also designed with a single processor in mind. However, it was extended for use on multiple processors. On the CRAY T90 or CRAY T3E at GFDL, compiler version 3.1.0.0 (or later) and message passing toolkit version 1.2.1.0 (or later) are required. Both SHMEM and MPI message passing protocols are supported through the GFDL message passing interface (http://www.gfdl.gov/ vb). Parallel I/O is supported through the GFDL parallel I/O interface (http://www.gfdl.gov/ vb).
