The LS-DYNA benchmark results clearly demonstrate that the Cray XD1
supercomputer, which is purpose-built for HPC code, significantly
outperforms other vendors' general-purpose Opteron-based systems, and also
turns in faster results than cluster systems that use Itanium 2 processors. The
x86-based Cray XD1 system supports a broad range of 32- and 64-bit HPC
applications on AMD Opteron single- or dual-core processors.
