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