Full Index for Basic foilset 
| This covers MPI from a user's point of view and is meant to be a supplement to other online resources from the MPI Forum, David Walker's Tutorial, Ian Foster's Book "Designing and Building Parallel Programs", Gropp,Lusk and Skjellum "Using MPI" |
| An Overview is based on subset of 6 routines that cover send/receive, environment inquiry (for rank and total number of processors) initialize and finalization with simple examples |
| Processor Groups, Collective Communication and Computation, Topologies, and Derived Datatypes are also discussed |
