    SGI Altix(TM) 3000
    1 GHz Itanium2(R)
    3 MB L3 cache, 256 kB L2 cache
    190 GB main memory
    SGI ProPack(TM) v.2.1

    Intel(R) Fortran Itanium(R) Compiler for Itanium(R)-based applications
    Version 7.0, Build 20021210
    compilation flags: -O3 -i8 -openmp -extend_source

    The "dplace" placement tool was used to ensure that there were two OpenMP
    threads per frontside bus, which matches the system architecture of two
    processors per frontside bus.
