NEW SYSTEMS

The National Supercomputing Center for Energy and the Environment is extremely pleased to announce the acquisition of an SGI/Cray Origin 2000 system as the newest addition to UNLV's high-performance computing facilities. The system will be shipped by SGI mid-December and should be available for general use by mid-to-late January.

The new system will dramatically enhance UNLV's computing capabilities. The initial tightly integrated system will have a peak performance of 3.9 billion floating point computations per second which will be increased to 6.4 billion floating point computat ions per second by the end of 1997. In addition to the Origin 2000, NSCEE will install a Cray YMP/EL system for mass storage management. These system will join other UNLV computing assets which include a Cray Y-MP, a Convex C-220, and a Sun MP-690 system to provide a total capability of over 4.8 billion floating point operations per second. NSCEE will also install an upgraded tape transport system increasing the mass storage capacity from 2.7 trillion bytes to 5.4 trillion bytes.

The Origin 2000 is an innovative new architecture based on distributed shared memory (DSM). DSM performance and bandwidth is significantly higher than older bus based systems. The initial configuration of our Origin 2000 system will be powered by 10 MIPS R10000 processors running at a clock rate of 195 MHz. The initial memory configuration will be 1.3 billion bytes (1.3 gigabytes). Our system will be one of the first group of Origin 2000 production systems installed around the world. Los Alamos National Laboratory recently selected the Origin 2000 system for their Accelerated Strategic Computing Initiative (ASCI).

The NSCEE mass storage system is based on the Cray data migration facility (DMF) software and StorageTek hardware. The StorageTek TimberLine 9490 Tape Cartridge Subsystem is the first-and only-tape subsystem that combines ultra-high performance tape trans port technologies with an industry-unique, Totally Parallel 1-by-1 controller transport architecture. The benefits from this StorageTek design innovation are dramatic. TimberLine delivers immediate improvements for traditional applications (such as NSCEE’s satellite image storage and retrieval system called SALICIN). TimberLine also creates revolutionary new application opportunities for substantial new benefits across various technical disciplines. The 9490 tape transport will double our total capacity a nd almost quadruple our mass storage performance throughput.
