[mpich-discuss] Collective comm not working

[Bibrak Qamar]

Hello all,


I am using mpich2-1.4.1p1 on a cluster of machines. I use mpiexec to run
application. The application starts on all the machines but cannot
successfully complete the Barrier().

What could be the problem, any guess?

Hello world from process 0 of 3 | Hostname = ccitsuseamd1
