Compaq 'Supercomputer' Demo Exceeds All Goals In Phase One of ASCI PathForward Program; System Demonstrates Scalable Performance Across 256 Alpha Processors.

HOUSTON--(BUSINESS WIRE)--July 14, 1999--

Compaq Computer Corporation (NYSE:CPQ) today announced that it has exceeded its ASCI (Accelerated Strategic Computing Initiative) PathForward phase one goals by successfully completing the first of three "supercomputers-from-commodity-parts" demonstrations. Today's demonstration is Compaq's largest and fastest supercomputer to date. Using 128 dual processor AlphaServer DS20 systems, Tru64 UNIX, and Quadrics switch technology, the Alpha-based supercomputer surpassed PathForward goals for memory bandwidth, process latency, and performance scaling across all 256 processors.

The Compaq demonstration system was assembled for and tested by the Department of Energy (DOE) as part of the ASCI PathForward program. The ASCI program is responsible for developing the computing capability needed to perform large-scale simulations of, and ensure confidence in, the safety, performance and reliability of the U.S. nuclear stockpile. A key element of the ASCI program, PathForward is a technology partnership program jointly administered by the DOE's Lawrence Livermore National Laboratory, Los Alamos National Laboratory, and Sandia National Laboratories.

Last year, the DOE awarded Compaq an $11 million contract over four years. Under terms of the contract, Compaq was required to demonstrate a system interconnect capable of tying together 128 Compaq Tru64 UNIX-based AlphaServer symmetric multiprocessing (SMP) nodes. Today's successful demonstration of the 256 processor Alpha-based system successfully completes phase one, surpassing PathForward goals for memory bandwidth, process latency, and performance. This breakthrough performance ultimately will help scientists solve bigger science problems much faster and at a lower cost.

Running on the AlphaServer DS20s, the switch and adapters deliver more than 200MB per second of message passing bandwidth to the MPI processes. One-way latency using an 8 byte MPI pingpong test was measured at less than 5.5 microseconds.

DOE used three codes as benchmarks to gauge how well the system's performance scaled as the number of CPUs was increased. This is a critical determinant for constructing much larger computer systems. All of the codes exhibited very good linear scaling from medium to large CPU counts. The machine was able to deliver 33 percent of peak performance running the ASCI code sPPM. Running a 120,000 element MPI-based Linpack NXN test yielded 603MFlops/CPU for a total computational capability of 154.4GFlops or 0.1544Teraflop. The capability of the system demonstrates the value of a high bandwidth, low latency switch network to inter connect the memory subsystems.

"I am very pleased with the excellent results that have been achieved to date," said Jim Tomkins, the Sandia Project Manager for the Compaq PathForward contract. "With this first demonstration system, Compaq has shown that it can build systems from commodity parts that will scale well on ASCI kinds of problems. I am eagerly looking forward to the future developments that will occur as part of this project."

"The platform component strategy of the ASCI program is to build integrated, highly scalable scientific computing capabilities from commodity, off-the-shelf building blocks at processing levels of 30TFLOPS in 2001 and 100TFLOPS in 2004," said Gilbert G. Weigand, Deputy Assistant Secretary for Strategic Computing and Simulation, Office of Defense Programs, U.S. Department of Energy. "With Compaq's demo today, they've successfully exceeded all ASCI PathForward phase one goals."

"Today's successful demo is further proof of the 64-bit AlphaServer Tru64 UNIX platform's ultra-high performance, scalability, and reliability," said Jesse Lipcon, Vice President of Compaq's High Performance Server Division. "We plan to continue to exceed the DOE goals by delivering the full potential of the Alpha platform not only for the most demanding scientific applications, but also for compute-intensive commercial and internetworking applications. In fact, we plan to use PathForward technology in our products two years early because of our successful partnership with the DOE."

Today's Compaq demonstration also reinforced and highlighted Compaq's collaboration with Quadrics Supercomputing World, Ltd. (QSW), which is owned by Alenia Aerospazio, a Finmeccanica Company, to provide a System Area Network (SAN) switch to enable the high speed connection of 128 AlphaServer DS20 systems. Compaq is employing QSW high-performance computer interconnect technology and parallel operating environment as part of its PathForward solution. This will enable configurations of AlphaServer clusters that deliver cost-effective, supercomputer-class performance in fields such as science, research and manufacturing.
