Subject: SCF Origin 2000 Retirement

Dear Researcher,

Now that the new IBM p690 system has been in production for some time,
it is time to phase out the SGI Origin 2000 systems.  This will be
done in stages.  The first machine to be decommissioned will be one of
the 64-processor machines, jacks.bu.edu, on Friday, February 28.
The rest will be powered down at appropriate intervals.  All of the 
SGI O2000 machines will be offline by June 1 of this year.

For those of you who have not yet made the transition from the SGI 
systems to the IBM systems, it is important to do so in the very 
near future.  If you have questions about, or would like help with,
porting your code to the new systems, you may contact our scientific
programming consultants, Kadin Tseng (kadin@bu.edu) or Doug Sondak
(sondak@bu.edu).  We have also established a repository of information
on the IBM SP and p690 machines, which may be found at
http://scv.bu.edu/SCV/IBMSP/.

lego.bu.edu will remain the interactive login machine.  The changes to 
the batch queues when jacks is shut down will be a change in the number
of slots, as follows:

Also, as part of the continuing development of the IBM p690 system we 
are in the very early stage of installing a new large storage solution.
