Ah, really?  When I asked about this a while ago, I was informed that it
would require nontrivial hacking.  Unfortunately my cluster already exists
that way and I have no further funding on that project to buy a Scyld
support contract so I let it drop.  If the situation has improved then I'll
have to have another look at Scyld.

I guess the important issue was dealing with the mapper.  It has to go on
one of the compute nodes, since the front end isn't on the Myrinet.
