Toward a Portable MPI Environment

• MPICH is a high-performance portable implementation of MPI (1).

• It runs on MPP's, clusters, and heterogeneous networks of workstations.

• In a wide variety of environments, one can do:

  • configure
  • make
  • mpicc -mpitrace myprog.c
  • mpirun -np 10 myprog
  • upshot myprog.log
  • to build, compile, run, and analyze performance.
