U.S. Department of Energy and SGI to Accelerate Research with New Open-Source Performance Analysis Tool

Moving Popular SpeedShop to Linux Will Serve as Model for

Creating HPC-Class Tools for Use on Parallel Linux Systems

    MOUNTAIN VIEW, Calif., Oct. 20 /PRNewswire-FirstCall/ -- In a joint effort
 with the U.S. Department of Energy's (DOE) National Nuclear Security
 Administration (NNSA) to make more sophisticated open-source performance tools
 available to government laboratories, universities and other researchers,
 Silicon Graphics (NYSE:   SGI) today announced it is developing an open-source
 version of the SGI(R) SpeedShop(TM) performance analysis tool. Aimed at
 accelerating research efforts on Linux(R) OS-based systems, the NNSA-funded
 project will provide the evolving open-source community with broad access to
 SpeedShop that for years has been a staple on IRIX(R), the world's most
 technically advanced UNIX(R) high-performance computing environment.
     "Cost-efficient Linux systems are becoming commonplace in the nation's
 research facilities, but the ecosystem of open-source tools and utilities
 hasn't matured as rapidly as the operating system itself, and this leaves
 researchers at a productivity disadvantage," said Thuc Hoang, Path Forward
 program manager, NNSA.
     "With the development of an open-source version of SGI's SpeedShop tool,
 researchers can begin relying on the same class of open-source parallel
 performance tools that they have used for years in HPC environments. This will
 ensure that researchers working on Linux systems -- not just at the NNSA but
 throughout the nation and the world -- can accelerate their research efforts
 by continuously optimizing application and system performance," Hoang added.
     Creating a Linux version of SpeedShop, named Open/SpeedShop, will make it
 easier for laboratory scientists and researchers to analyze the performance of
 applications and tasks while eliminating bottlenecks and bugs, maximizing
 overall application performance, and improving the quality of data and
 results. SGI is collaborating with the University of Wisconsin and the
 University of Maryland on the project.
     SGI SpeedShop provides a wide variety of experiments to help users
 identify and remove performance obstacles, pinpoint system resource usage, and
 detect memory leaks. Open/SpeedShop for Linux OS-based computing systems
 running on a wide range of computing platforms will be made available to the
 open-source community to accelerate independent use and development. It will
 feature core SpeedShop components such as support for single system image and
 cluster configurations, exclusive and inclusive user time sampling, program
 counter sampling, MPI call tracing, input/output tracing, floating point
 exception tracing, and CPU hardware performance counter experiments. The new
 version's modular design will also enable users to extend the tool's
 functionality by adding their own performance experiments to monitor
 application performance.
     "SGI is excited to participate in this effort, not only because of our
 growing commitment to the open-source community, but also because this project
 can serve as the model for future development of open-source tools designed
 for parallel computing environments," said Rich Altmaier, vice president of
 engineering, Storage and Software Group, SGI. "The baseline SpeedShop code
 will provide Linux users with a foundation for running performance experiments
 on their systems and applications, while the Pro-series plug-ins from SGI can
 extend the tool for more sophisticated use."
     Software development groups within the NNSA's ASC program plan to leverage
 the open-source version of SpeedShop to develop large-scale experiments of
 their own. In addition to development of the baseline open-source version of
 SpeedShop, SGI plans to independently develop Pro-series plug-ins and
 enhancements that will be made available for commercial license. Both the
 open-source code and the commercial Pro-series plug-ins will be based on
 dynamic instrumentation, developed at the Universities of Wisconsin and
 Maryland, which will reduce the amount of performance data generated, by being
 more selective about what performance data the tools will gather, and thus
 allow more efficient measurements and faster conclusions for end users.
     SGI and the NNSA expect to release the Linux version of SpeedShop in 2006.

     PathForward is a technology vendor partnership project of the National
 Nuclear Security Administration's Advanced Simulation and Computing (ASC)
 Program -- an integral and vital element of our nation's Stockpile Stewardship
 Program, by which the U.S. ensures confidence in the safety, performance, and
 reliability of its nuclear stockpile. ASC provides the integrating simulation
 and modeling capabilities and technologies needed to combine new and old
 experimental data, past nuclear test data, and past design and engineering
 experience into a powerful tool for future design assessment and certification
 of nuclear weapons and their components. Through PathForward, ASC strives to
 make strategic, targeted investments with its vendor partners to accelerate
 the development of hardware and software technologies needed to ensure that
 complete, balanced systems for capability and capacity computing at Lawrence
 Livermore National Laboratory (LLNL), Los Alamos National Laboratory (LANL),
 and Sandia National Laboratories (SNL) are available in the marketplace for
 out-year procurements by the program.
