Benchmarking mpich

The mpich/examples/perftest directory contains a sophisticated tool for measuring latency and bandwidth for mpich on your system. To run it, first make sure that mpich was configured with the -mpe option. Then go to mpich/examples/perftest and do
    make
    mpirun -np 2 mpptest -gnuplot > out.gpl
The file out.gpl will then contain the necessary gnuplot commands. The file mppout.gpl will contain the data. To view the data with gnuplot, use:
    gnuplot out.gpl
or use
    load 'out.gpl'
from within gnuplot.
