MPI parallel computing system implementation, MPD version

 MPICH is a robust and flexible implementation of the MPI (Message Passing
 Interface). MPI is often used with parallel or distributed computing
 projects. MPICH is a multi-platform, configurable system (development,
 execution, libraries, etc) for MPI. It can achieve parallelism using
 networked machines or using multitasking on a single machine.
 .
 This version is compiled with ch_p4mpd support, which requires mpd daemons
 running on each of the cluster nodes. This method is faster than ch_p4.
