A more up to date version of this material can be found in the User's Guide for MPE and in the file mpe/README.
It is anticipated that mpich will continue to accumulate extension routines of various kinds. We keep them in a library we call mpe, for MultiProcessing Environment.
Currently the main components of the MPE are
A set of routines for creating logfiles for examination by various graphical visualization tools : upshot, nupshot, Jumpshot-2 or Jumpshot-3.
A shared-display parallel X graphics library.
Routines for sequentializing a section of code being executed in parallel.
Debugger setup routines.
