Los Alamos Message Passing Interface
LA-MPI is an implementation of the Message Passing Interface (MPI) motivated by a growing need for fault tolerance at the software level in large high-performance computing (HPC) systems. Emphasis is placed in particular on complex HPC systems using commercial off-the-shelf components, where system-wide error rates may become unacceptable on long application runs.
