The MPE Library of Useful Extensions

It is anticipated that mpich will continue to accrete extension routines of various kinds. Some of them may ultimately become part of an extended MPI Standard. In the meantime, we keep them in a library we call mpe, for MultiProcessing Environment. Currently the main components of the mpe library are

• a set of routines for creating logfiles for examination by upshot,
• a shared-display parallel X graphics library,
• routines for sequentializing a section of code being executed in parallel,
• debugger setup routines.
