Note that I only recommend the CVS copy of LAM if you're ok with
development-quality code.  It is *not* guaranteed to be stable.  That
being said, it's *usually* stable, but...

See http://www.lam-mpi.org/cvs/ if you're interested.  And then read the
lamssi(7) and lamssi_rpi(7) man pages for details on setting the run-time
parameters.

Otherwise, I'd download a tarball of the current stable LAM (6.5.8) from
our main download site: http://www.lam-mpi.org/download/ and use the
./configure option to set the buffer size at compile time.

As for integrating that with OSCAR, IIRC, in 1.2.1 there is a script in
/etc/profile.d that sets up the LAM path (mpi-01lam.*, I think?).  You can
simply edit that file to put in the path and manpath to your "new" LAM.
You must either do this on all nodes, or edit it on the server node and
cpush that file out to all the client nodes.
