As root (or installer), download source from http://www.mcs.anl.gov/research/projects/mpich2/
- ignore the older Web pages.
Downloaded and uncompressed into /panfs/usr/local/src/mpich2-1.2.1 on dl1.
Load appropriate compiler module, e.g. compiler/pgi/8.0-3
there is a bug in mpd.py which affects Centos-5.3 and equivalent SciLinux distros. See https://trac.mcs.anl.gov/projects/mpich2/ticket/974
. You can download the fix from https://trac.mcs.anl.gov/projects/mpich2/export/5923/mpich2/trunk/src/pm/mpd/mpd.py
Put this in mpich2-1.2.1/src/pm/mpd/mpd.py
In source dir ./configure CC=pgcc CXX=pgCC F77=pgf77 F90=pff90 -enable-f77 -enable -f90 --prefix=/panfs/usr/local/mpich-2-1.2.1/pgi
make && make install
This should get you a working installation. Look at the README file and doc/installguide/install.pdf and run the tests using mpd.
on our dl1 system I could not run the tests from the head node. This is because mpdboot uses ssh and to connect back from a compute node to the head node with ssh requires a password - so it hangs. Log onto a compute node and do the tests there.
Finally, Streamline Computing have provided a nice script called mpich2sub to run jobs.
Finally, finally, I made modules like mpich/2-1.2.1/pgi to make things easier for users.
And before signing off - remember to tell users that they need a .mpi.conf file in their home directory, and also that they need to use mpich2sub instead of ompisub.
