[MPICH] Using MPICH on Mac?

[James Frye]

Hi,

Just wondering whether MPICH2 will run on a MacOS 10 system?  And if so, 
whether there's anything special that the user needs to do?

I seem to remember occasional mentions on the list of people running on 
Mac machines, but I skipped past them at the time.  Now I have a user who 
wants to learn MPI programming on their Mac, and I can't find anything 
explicit when I look back through the archives.

The user would just be running on the single machine, not actually trying 
to set up a Mac cluster.

Thanks,
James
