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.
