    Phoronix: HPL-GPU 1.0 Released For GPU Super Computing

    Matthias Bach, a researcher and developer on high-performance computing with the Goethe Universitaet Frankfurt am Main, has written in to inform us of this German university's release of HPL-GPU 1.0. The HPL-GPU software package is a rewritten version of the LINPACK library that is re-engineered to run atop CALDGEMM, which is a DGEMM implementation developed at this university designed to run atop the latest AMD graphics processors...

    You can get the NVIDIA number from slide 12 of one of NVIDIAs presentations from SC10: http://www.nvidia.com/content/PDF/sc...llips_SC10.pdf

    NVIDIAs marketing number is in that area. I don't think they would understate their performance.

    So you are unable to qualify the "The code also stomps NVIDIA, reaching 497 flops DGEMM on the HD5870 where NVIDIA only reaches around 300 on the much more expensive Tesla systems" statement. That is a bit misleading don't you think as you have no actual verification?

    The open driver currently neither supports CAL nor OpenCL, so it's (nearly) impossible to use it for GPGPU.

    I run the latest kde with the latest open source AMD/ati video card, so my linux system is neither stable nor fast...
    but that's actually your own fault. Running latest git tree won't always give you best performance and least problems. XD

    When did we surpass Windows in usage? Or do you mean something else?

    Heh... There is little reason that the FOSS driver won't eventually catch up.

    Surpass might be a bit of a stretch, but there's little reason to believe that we won't get there. They said the same thing about our OS choice back in earlier days, remember...

    Yep.

    I hate to admit it, but I was once a firm believer in an open source only strategy. I said it here on this forum many times. But in light of this, I admit that a closed source optimized binary is better overall in this situation.

    I for one am glad the binary exists in this particular case, because we woulnt have this new open source code without it.
