[MPICH] mpich2 on G5

[Rachid Benshila]

Hi

I am using MPICH2 on a mac G5 for a fortran 90 code. I have 2 different 
questions :

- installing MPICH2 with gcc and xlf90 works on panther (10.3) but 
failed on tiger(10.4). I know xlf90 is not fully supported on tiger, 
but It seems to be related to the gcc version,  I am not sure about 
that. The mpich libraries are created but are not recognized as 
librariries when I try to use it. Does someone have any experience 
about that ?

- I am using  a single computer with 2 cpu and 2 different aims.
The first one  is to do preliminary tests for mpi before running on a 
cluster. Here I do not mind of the performances and I am using the mpd 
daemon as if I was working on two different computers, and it works 
fine.
My second aim would be to perform "production" runs on my computer. Is 
there a way to take advantage of running on a bi-processor using MPICH. 
It is probably closer related to the code itself, but are there basics 
recommandations to install MPICH ? Should I better use gforker instead 
of mpd ? If someone use to run on a G5 or on a multi-processors 
computer in general, any advice would be welcome.

Thanks a lot

Rachid
