Message Passing Interface (MPI) installation

What is it?

• a widely used standard for writing message-passing programs
• designed for high performance on both massively parallel machines and on workstation clusters
• developed by a broadly based committee of vendors, implementors, and users
• an amalgam of the most attractive features of a number of existing message passing systems

What is MPICH?

• a portable implementation of MPI
• contains MPI library as well as an MPI programming environment and a convenient interface

Installation of MPICH

• download MPICH source from http://www-unix.mcs.anl.gov/mpi/mpich/
• 'configure' and 'make' on unisys08 (Mike's desktop)
• export and mount to node01, node05, and node08 via NFS

Why?

• allows for passing of data between the desktops and nodes (necessary for operation of the Sun Grid Engine)
