our computational flagship, will be retired in mid-June this year. We
urge current users to port their codes to HYDRA as soon as practicable
and to back up all valuable files not residing in their home
directories. Because COSMOS has not been under hardware or software
maintenance for the last three years, a repair from a hardware failure
may just be too costly to afford. Supercomputing Facility analysts are
always available to help with with the transition to HYDRA.
By its retirement, COSMOS will have capped five and a half years of
extremely reliable (99.9% uptime) operation. It remains the favorite of
many users and the only system on campus with large enough RAM (128GB)
to accommodate serial jobs that require large amounts of it . Chemistry
has expressed interest in assuming control and administration of COSMOS
and plans to welcome users from other areas. We will keep our users
posted on any relevant developments.

Dear COSMOS users:
The system will be powered off at 9 AM of June 29, 2009. Thereafter, the
Chemistry department will take over its operation. This will be the
LAST notice about the decommissioning of COSMOS.
The Facility will delete all user data from the system right before
power off. Since COSMOS is not under maintenance, the resumption of its
operation, much less a prompt one, is not a certainty. Although we have
every expectation that the transfer will be smooth and uneventful, we
cannot exclude misadventures. The latter may even include junking it
because of high repair costs.
