Tau/Ceti
Description:
Tau/Ceti is a Sunfire 6800 with 24 processors and
72G of RAM. The machine usually runs as tau.umiacs.umd.edu,
but will occasionally be partitioned into two machines,
the second being ceti. Tau is the more stable half
of the pair, with Ceti being used for kernel and hardware
hacking.
Currently, the machine is combined into one domain
(ceti) with all hardware components running Solaris
9. |

Usage Policy and Reservations:
People have needs to do experiments on tau during which they require
exclusive use of the entire machine. Please pay attention to requests
on tau-forum for exclusive use.
Use of tau is discouraged for long running jobs. In general, you
shouldn't run any job on tau that takes more several hours unless
you need either the processors or memory uniquely available on tau. If you
want
to run a job on tau that is going to take more than some small number of
hours, you should send email to tau-forum warning people in advance,
and be prepared to justify your need for tau.
If you just need lots of cycles, there are other, better sources of
cycles available. In particular, you should consider using Condor
