    Breakthrough Results with SGI Shared-Memory Architecture and 64-Bit Linux Accelerate Research...
    Tuesday October 21 2003 @ 05:36PM EDT

    MOUNTAIN VIEW, Calif. (Oct. 21, 2003) -- SGI (NYSE: SGI) today announced that large-scale SGI ® Altix 3000 systems have once again generated breakthrough performance results on demanding scientific applications. Recent achievements include attaining record levels of sustained performance and scalability on a 256-processor global shared-memory SGI Altix 3000 system, the largest such system ever to run on the Linux ® operating system.

    The breakthroughs were achieved at NASA Ames Research Center as part of an agency research program between Ames, Goddard Space Flight Center, and the Jet Propulsion Laboratory (JPL) to accelerate the solution of large-scale problems in the earth sciences domain. To demonstrate the scalability and performance of the Altix system, NASA selected the ECCO (Estimating the Circulation and Climate of the Ocean) application, the product of a collaborative effort between the Massachusetts Institute of Technology, NASAs JPL, and the Scripps Institution of Oceanography. ECCOs importance is in improving the understanding of large-scale ocean dynamics by assimilating observational data gathered from satellites and in situ hydrographic measurements.

    Running on NASA Ames 256-processor single system image, the ECCO ocean circulation model ran a one-quarter-degree global problem at a rate of 1.4 simulated years per wall clock daythe fastest ECCO result ever achieved on any system. Working with the JPL team, the Altix system has enabled us to complete computations in ocean modeling involving terabytes of output at record speeds, said James Taft, president of Sienna Software, Inc. and currently a consultant at NASA Ames.

    Fueled by an unquenchable thirst for discovery, our partners at NASA are once again staking new ground in computational science, said Dave Parry, senior vice president and general manager, Server and Platform Group, SGI. Our relationship with NASA Ames spans more than two decades, and todays achievement with SGI Altix 3000 proves that this remarkable collaboration continues to show the world what is possible with computing technology.

    As part of their testing and evaluation of the 256-processor Altix system, researchers at NASA said they have run more than 40 benchmarks used for system evaluations at the facility. The benchmarks include production computational fluid dynamics (CFD) codes, ocean and atmospheric circulation models, numerical analysis and other mission-relevant applications at NASA. The tests evaluated single processor performance, the parallel scaling of OpenMP, MPI, and MLP, as well as interference effects in large throughput scenarios. NASA reported that the SGI Altix system performed well on all tests, and yielded significant per-processor performance gains while maintaining scalability.

    The results weve been seeing are extraordinary for 256 processors, said Taft. For instance, the OVERFLOW CFD application has generated 200 GFLOPS of sustained performance with 256 processors, which is exactly twice the performance that NASA Ames team achieved with the first 128-processor Altix system all without optimizing application code.

    NASA sought to implement a 256-processor shared-memory system because many key production codes have been optimized to run on such systems. Researchers reported that running their codes on a 256-processor shared-memory system has allowed the facility to see immediate scalability benefits with little or no porting or tuning. The Altix family of servers combines industry-standard 64-bit Linux with the Intel ® Itanium ® 2 processor family and SGI ® NUMAflex architecture to enable global shared memory systems from a few to hundreds of processors, which is a first for Linux OS-based computing. Powered by the third-generation NUMAflex supercomputing architecture, even the largest data sets can be handled and analyzed with ease and in record time.

    Only the SGI Altix 3000 family of servers is designed around this scalable shared-memory architecture that analyzes data sets as whole entities, without breaking them up into smaller segments to be handled by individual processors. The Altix architecture has proven ideal both for complex shared-memory applications running on a large single system image, and for communication-intensive applications optimized for clustering.

    Clearly, the economic environment for large-scale systems continues to force designers to amortize as much R&D as possible from broader horizontal markets. Now we have one company integrating and creating the system memory interconnect, another providing the processing elements, and the open-source community providing a substantial part of the system software, said Bob Ciotti, lead for the Tera-scale Application Group at NASA Ames. This type of arrangement is resulting in systems that are highly competitive in price and performance for large-scale computation.

    While the achievement at NASA was driven to meet the facilitys own research objectives, the announcement builds on the formal efforts of SGI and its customers to continue to drive the scalability of the SGI Altix platform and of Linux itself. In August, the U.S. Naval Research Laboratory (NRL) became the first SGI customer under its global beta program to install a 128-processor single system image SGI Altix 3000 supercomputer. The announcement came on the heels of the August launch of the global beta program, whose participants, along with NRL and NASA Ames, include Oak Ridge National Laboratory in Oak Ridge, Tenn., Pacific Northwest National Laboratory in Richland, Wash., the University of Queensland in Brisbane, Australia, and The Computing Center at Johannes Kepler University in Linz, Austria.

    Availability Scalable SGI Altix 3000 systems are available today in server configurations of 4 to 64 processors, and supercluster configurations of 4 to 256 processors. For customers demanding even larger Altix superclusters, SGI plans to support configurations of 512 processors in October 2003 and 1,024 processors in May 2004. Additional Altix system technical and availability information is posted on www.sgi.com/servers/altix.

    Since its introduction in January, SGI Altix 3000 has been recognized as the first Linux cluster that scales up to 64 processors within each node and the first cluster to allow global shared-memory access across nodes. Inspired by the success of the SGI Altix family and the powerful combination of standard Linux running on 64-bit Intel processors, more than 60 high-performance manufacturing, science, energy and environmental applications have been ported by their commercial developers to the 64-bit Linux environment. Over two thirds of these applications have certified and optimized their code for differentiated performance on the Altix platform.
