    OK, here are some numbers for a GTX470 and Linux 64Bit:

    Load Time
    55% 0h55m for 1 WU
    79% 1h15m for 2 WU
    84% 1h55m for 3 WU

    The CPU is a Phenom IIx4 945 at stock speed. Running RNA on the free cores.

    @mickydl* Where is your "CAL ATI Radeon HD5x00 series (Redwood) (1024MB) driver: 1.4.815" crunching? It seems that pc, AuthenticAMD AMD Phenom(tm) II X4 940 Processor [Family 16 Model 4 Stepping 2] (4 processors), is ONLY doing cpu units!

    There are not many projects that have ATI applications for LINUX. The only one that works without too much trouble is DNETC. That's what it is doing, though I would love to do something else with that card - like Einstein or Milkyway :)

    Michael

    But your rac over there is only 20k, tou should be waaaaay above that with a 58xx card! I have a 5870 on Dnetc and am up above 260k and still climbing, I use Windows but that can't be the difference!
    Here are the times and credits for one of my units:
    904.91 11.95 3,091.20 DNETC@Home v1.31 (ati14)
    and for one of your units:
    10,777.46 99.83 3,292.45 DNETC@Home v1.02 (ati14)

    For some reason yours is using a much different version of the Dnetc software, probably the Linux version. I can't believe it is that much slower!! My pc is doing units in about 15 minutes each, why is yours taking soooo much longer?!

    The card I'm running in that machine is a HD5670 that has considerably less power that the HD58xx. I am also not running them 24/7.

    Still, I have the feeling that the Linux application is also slower than the Windows app. When I put the card into the machine a couple of month ago I did some research and seem to recall that the runtime for the 5K WUs in DNETC are about half the time on windows than what I'm seeing on my Linux machine.

    GPUGRID is behaving similarly on NVIDIA GPUs. I am seeing runtimes on my GTX470 on Linux that are about a factor 2-3 higher than on Windows.

      Vista and Win7 take a big hit on GPUGrid ... Linux and XP perform much better. They have not worked around the WDM layer M$ introduced with Vista yet.

        Ahhh that makes sense then.

          I have two windows computer 1 with vista and a ati 4890 card and a windows 7 machine with a ati 5870 card. I can,t get the cards to work. one computer is only 8 months old. they just say you do not have a nvidia gpu on board. what do I have to to get them to work. boinc is the latest version. And how do I know if they are working?

            Einstein only supports CUDA

              Einstein only supports CUDA apps at this moment, which run exclusively on Nvidia GPUs.

              Only when OpenCL will be available around here, can ATI cards be used for calculations at Einstein. Until that time, they're great for use with screen savers.

                Use it in MilkyWay@Home! MW application can harvest a great performance from ATI TOP-cards. :)

                  I am currently running an ATI HD5850 on DNETC until I finish my target. This graphics card currently uses the ATI/AMD 10.11 APP driver for XP 32bit. According to GPU-Z V0.5.1 this GPU also runs OpenCL.

                  I assume as this runs OpenCL that it could crunch Einstein when an OpenCL GPU client is developed?

                    To stay in correct terminology: Application, not client.
                    Client == BOINC
                    Application == Einstein, Seti, DNetc, Milkyway, you name it.

                    BOINC detects the GPUs already, so under normal circumstances, when the project releases an OpenCL application, your GPU can use this application. All Nvidia GPUs that can do CUDA can do OpenCL; for ATI GPUs it's the 4xx0 series and higher.

                        Maybe a MOD should change the thread title to more clearly indicate that this thread is not about ATI performance at Einstein, because no such ap is in sight yet.
