    SEATTLE, SC|05, Nov. 15 /PRNewswire-FirstCall/ -- Culminating a year of
 joint development, the U.S. Department of Energy's (DOE) National Nuclear
 Security Administration (NNSA) and Silicon Graphics (OTC Bulletin Board:   SGID)
 today announced that an open-source version of the SGI(R) SpeedShop(TM)
 performance analysis tool is now available to developers.
     Open|SpeedShop(TM), an open-source, multi-platform Linux(R) tool, helps
 developers and end users analyze the performance of applications running on
 single-node to large-scale IA32, IA64, EM64T and AMD64 platforms. The new
 open-source tool is the result of a cooperative government/industry effort to
 make more sophisticated open-source performance tools available to government
 laboratories, universities and other researchers.
     At the SC|05 Conference Nov. 12-18 in Seattle, Linux application
 developers can attend a Birds-of-a-Feather session and ongoing demonstrations
 of Open|SpeedShop.
     -- Birds-of-a-Feather session: 12:15 to 1:15 p.m. Wednesday, Nov. 16, in
        Room 615-616 of the Washington State Convention and Trade Center.
        Jim Galarowicz from SGI and Martin Schulz from Lawrence Livermore
        National Laboratory will discuss the current status of Open|SpeedShop
        and the opportunities it presents to high-performance computing (HPC)
        application developers and users.
     -- Live demonstrations of Open|SpeedShop:  Ongoing in the SGI Booth
        (No. 602) and the NNSA Advanced Simulation and Computing (ASC) Tri-Labs
        Booth (No. 402).
     Developed by SGI in collaboration with Lawrence Livermore National
 Laboratory, Los Alamos National Laboratory, and Sandia National Laboratories,
 Open|SpeedShop utilizes dynamic instrumentation technology developed at the
 University of Wisconsin and University of Maryland.
     The tool's base functionality includes program counter sampling, exclusive
 and inclusive user time, CPU hardware performance counter, MPI event tracing,
 I/O call tracing, and floating-point exception experiments. Designed to be
 modular and extensible, Open|SpeedShop supports several levels of plug-ins
 that allow users to add their own performance experiments. The tool's
 infrastructure and base components are being released open source under GPL
 and LGPL.
     Key features of the powerful open-source tool include:
     -- Three modes of operation: batch, interactive command line interface,
        and graphical user interface
     -- Multi-platform single system image, traditional cluster, and SGI super
        cluster support
     -- Support for large numbers of processes, threads, and ranks
