NCAR Weather Group Multiplies Its Raw Computing Power By Ten -- At No Direct Cost To NCAR

October 27, 1998

BOULDER--A weather research group at the National Center for Atmospheric Research has just upped its computing power ten times at no direct cost to NCAR through an innovative loan arrangement with Compaq Computer Corporation and iMSC Corporation, a computer consulting firm. On Wednesday, October 28, NCAR will celebrate the arrival of 42 new workstations and 7 high-end, multiprocessor AlphaServers worth $8.7 million from Compaq. IMSC originated the loan with Digital Equipment Corporation, which was recently acquired by Compaq. NCAR's primary sponsor is the National Science Foundation.

NCAR's Mesoscale and Microscale Meteorology Division (MMM) will use this increase in its raw computing power primarily to develop further the MM5 computer model, a pre-eminent weather research and forecast tool used around the world. The division expects to run the state-of-the-art model at a resolution not previously possible for simulating smaller-scale atmospheric features such as thunderstorms and other weather phenomena. According to MMM director Robert Gall, the new hardware will have a "huge" impact on the group's work on a vital data assimilation program, which will ultimately benefit the entire atmospheric science community.

"We're all very excited," says Gall. "At a time when research dollars and computer allocations are harder to come by, an opportunity like this can have a tremendous beneficial impact on our work."

iMSC teamed with six Colorado investors to form Advanced Research Alliance. ARA purchased the hardware at a substantial discount from Compaq and then lent it to MMM. In exchange, MMM will test and evaluate the systems and provide input to iMSC and Compaq for reconfiguring and redesigning the systems for scientific applications. At specified times during the three-year period, iMSC will upgrade the hardware (through steps such as chip replacements) and ARA will sell the used components. In 2001, ARA will sell the entire set of computers. This collaboration will result in a win-win-win situation for the three parties. ARA will have profited from its sales, MMM will have made otherwise impossible scientific leaps through the use of the computers, and Compaq will have obtained exposure and proof-of-performance for its high-end product line.

During the three years of the NCAR loan, iMSC will use a similar suite of Compaq machines to refine a version of MM5 that can be run by nonscientists on the Windows NT operating system. This version can be used by business and industry decision makers, government emergency managers, and even high school students.

The AlphaServers, which have been on the market since 1991, are the chief products in Compaq's high-performance computing division. At its aggregate peak, the group of AlphaServers and Alpha workstations at NCAR could in theory deliver 118 gigaflops (118 billion floating-point operations per second). In practice, however, each of the single- processor workstations--which now have the same 600 MHz chips as the multiprocessor servers--runs the MM5 code at approximately 200 megaflops.

NCAR is managed by the University Corporation for Atmospheric Research (UCAR) under sponsorship by the National Science Foundation. UCAR is a consortium of more than 60 universities offering Ph.D.s in atmospheric and related sciences.
Note to Editors: Reporters are invited to attend the ribbon-cutting ceremony at NCAR's Foothills Laboratory auditorium (3450 Mitchell Lane, Boulder) at 3:00 p.m. on Wednesday, October 28. Please arrive at 2:30 for interviews with MMM director Robert Gall, iMSC president Paul Chen, ARA assistant director Ned Sperry, and Compaq director of high-performance computing William Blake.
