Hi,

I'm trying to run the test fortran program and it works fine if I run
with -np 4 or less, but if I try more, I get the following kind of
errors.  The C program works fine with as many as 12 processors.  Does
anyone have any idea what I might be doing wrong?

[buber@burdina01] >/usr/local/mpich/bin/mpirun -np 5 pi3
