As root (or installer), download source from - 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

mkdir /panfs/usr/local/mpich-2-1.2.1/pgi

Note there is a bug in which affects Centos-5.3 and equivalent SciLinux distros. See . You can download the fix from .

Put this in mpich2-1.2.1/src/pm/mpd/

In source dir ./configure --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.

Note 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.
