Massively Parallel Mesoscale Model

#raggedright425#

% MPMM is a fine-grained dynamic decomposition of the Penn State/NCAR Mesoscale Model version 5. Each set of four horizontal grid points is represented as a parallel process running under PCN (see Section #secPCN#205>), providing a transparent mechanism for redistributing load between physical processors. The work is being done in collaboration with the developers of the original Cray model (who are at NCAR). This program is used for real-time forecasting and climate prediction. Work on this code is continuing; the SP1 provides a better development environment than other parallel systems, in part because each node provides a full Unix environment. %
