NPAC has a substantial computer infrastructure, including networked workstations, Mac and PC equipment, and various parallel computers. Parallel and distributed platforms include a 12-node IBM SP2, an 8-node DEC Alphafarm interconnected with a Gigaswitch, an 8-node Sun UltraSPARC cluster which will be interconnected with an ATM network shortly. These clusters are shared by all NPAC users, but available in dedicated parallel mode on a reservation basis. An 8-CPU SGI machine with R10000 processors is also available, providing a shared-memory parallel platform for testing purposes.
NPAC has a system support group which handles day to day operation and maintenance of the computer facilities.
