Loadleveler is derived from the University of Wisconsin's Condor. I had
a look at Condor some time ago in a pre-AFS version, and it seemed
quite good, with neat features like checkpointing and process migration
between machines.
However - and here I'm speaking about Condor, not IBM Loadlever, which
may now have been changed out of all recognition - it had one real
problem for sites like ours, which is that the context of a job - it's
checkpoints and I/O structures are maintained on the *submitting*
workstation, not (as we want) centrally on a server. Also, the
checkpointing support had to be compiled into the application being run.
A better alternative for Cranfield and probably many other AFS sites is
DQS from Florida State University, with AFS extensions from Pittsburgh
Supercompter Centre. I have just built this (v 2.1.5), and I'm very
impressed. I'm just finishing off adding MIT Kerberos extensions, and
then we'll go live with it. No chekpointing or process migration (yet)
but just about everything else one could wish for, and just about every
platform one could want is supported.
Oh yes. DQS is free, folks. :-)
