[mpich-discuss] Example MPICH2 multicore host file?

[Steve Smith]

I am running mpich2 on two multicore machines (linux dual-quad-core  
and OSX dual-core).

I haven't had any problems with building and running code. However,  
I've seen some behavior that makes me wonder if data/processing is  
actually being subdivided between my cores - or whether they are all  
getting the same data.

I have not seen an example of a working MPICH2 hostfile. Based on the  
OPENMPI ans MPICH1 examples at http://cs.calvin.edu/curriculum/cs/374/homework/MPI/01/multicoreHostFiles.html 
  I'm thinking my MPICH2 hostfile should have a different format.

Can anyone point me to a working example MPICH2 multicore hostfile?

Sincerely,
