     2= Part I Message Passing Interface; MPI =
     3* A standardized and portable message-passing system
     4* Not a new language ---- Library of functions
     5* Scales to over 100k processors
     6* Runs on distributed memory cluster systems.
     7* Portable
     8* Explicit parallel programming (unlike OpenMP)
     9* No shared variables (unlike OpenMP)

     12== MPI’s Execution model ==
     13* All processors execute same program, but with difference data. (no fork & join)
     14* Variable on each are all private.
     15* Data that must be shared is explicitly send between processors.
