[Wrf-users] mpich2 and/or openmpi?

[Mahally Kudsy]

Using mpi is really amazing. I succesfully installed on a dual core
processor for RegCM4. Using openmpi it cuts running time to half.
Unfortunately, I have not successfully made installation for wrf.
On multiple nodes, you should have identical installation on each nodes.
including the mpi's (regardless which kind it is). You have to install sshd
and enabling automatic logins as well,so the master node can distribute the
computational job to the other nodes
