mpich trouble in testing?
I upgraded our four alphas to testing, with mpich 1.2.1-1, and rebuilt
PETSc and an application linked to it, but am having some trouble. When
I do "mpirun -np 1 ./ex9", it's fine, but with -np 2, it sits for a
while, then says, "ALF.MIT.EDU: Connection refused".
ALF.MIT.EDU has nothing to do with anything in
/etc/mpich/machines.LINUX, it's in a completely different subnet!
Note that this was working just fine on the potato mpich... Any ideas?
