    GPUPI - SuperPI on the GPU

    in Benchmark software

    Posted

    Thanks for your feedback.

     

    Seems like the NVIDIA drivers make no difference betweeen GTX 560-448 and a normal one. But the number of Compute Units are different, so I can fix this on my side. It will be included in my next release.

     

    HD 6870 lacks double precision support indeed. No chance to run these cards with any version of the benchmark, sry.

    GPUPI for CPU "invalid result?"

    It was always slower for me and I've tested it on quite a few cpus. Why install the driver, sdk can be installed without it. Except 3.0, but that's beta anyway.
    Have a look at the best 100M scores, most of them go for the Intel drivers, like here.

    You have to know that 100M uses the kernel with only 64 bit arithmetic, while 1B uses 64 bit for partial results up to and including 500M, but a special 128 bit arithmetic kernel for above. That's where the AMD drivers are strong.

     

    I would not go for the APP SDK because the drivers are too old. With the 3.0 beta you will only get the Omega 14.2 Catalyst driver. Newer versions of the OpenCL driver are currently only available with the Catalyst for graphics cards.

    Yes, it would be possible to implement a version running on any platform that supports CUDA and/or OpenCL, but there are no plans yet. I am currently focusing my time on GPUPI 2.2 which will bring some interesting improvements. Can't promise anything right now. ;)

    does not create a file once completed. no option to save a file at all. and no option to submit. .. .using 2.1.1. . soooo how does one go about submitting this ?? ?
    This is not a 24/7 hotline, it's a support thread. I check it about 5 to 6 times a day, but sometimes I am sleeping. :)

     

    About your problem: After a valid run goto to "Submit to HWBOT" in the menu. A new dialog will open and allow you to "Save to file".

    I observed, like on this screen (http://img.hwbot.org/u93743/image_id_1405285.jpg), that setting a high batch size reduce the number of loops for a same bench.

    It's an expected behavior ? ^^

    Yes, that's perfectly normal behaviour. It's only possible with 100M and a batch size of 100M. The reason for this is that only 4 batches are sent to the CPU to calculate the result, so the benchmark can't split it up into the usual 20 steps.

     

    Thanks Massman! I will introduce a progress bar for submission in the next version, that will make slower uploads more visual. We can also add the mainboard vendor, mainboard name, amount of memory and so. There is still some potential to improve the integration. :)

    I've finished and uploaded GPUPI 2.1.1 which introduces serveral smaller bugfixes:

     

    • Detection of operating system is no longer including language dependend suffixes. (thx to Taloken & COMIAS)
    • Submission to HWBOT can now be started with an opened result popup "Pi calculation done" (thx to der8auer)
    • Fixed hardware detection for Core i7 980X/990X/995X and QX9750/QX9770/QX9775.

     

    Please test it and let me know if that fixes all current issues.

    rtsurfer, newlife: It's impossible that the other cards are helping in any way if they are not part of the calculation. There is a slim chance for a bug (there always is), but I doubt it because it's a very basic functionality. It's much more likely to be something else like a tweak or a very good combination of parameters and driver, I honestly don't know. The moderation should ask for more proof like a video or an explanation.

     

    Roman, thanks for your feedback. Very much appreciated!

    It's fine to close the popup before submission, I actually implemented it this way. But you are right, people would expect it to work the same way as in SuperPi where the popup had to be part of the screenshot. I will add the possibility to submit with an opened popup in the next version.

     

    COMIAS, your exotic Windows versions are the problem indeed. "Microsoft Windows*7 Édition Intégrale" ... ;)

    This will be fixed with GPUPI 2.1.1, a minor bugfix release coming in the next few days (as soon as possible).

    Seems to be a problem with the encoding of your special windows version: Microsoft Windows*7 Édition Familiale Premium

    I will look into it today.

     

    Don't bother doing anything to the data files, they are encrypted and submitted with an encrypted checksum. You can't change anything in these files. ;)

    I think you can find number of physical sockets through WMI as well.

    In the Win32_Processor class, loop through each processor and check their SocketDesignation. The number of unique socketdesignation's should be the physical count of processors.

    That should do it, thanks. I will put it into GPUPI 2.1.1. :)

    i found an other problem whit the e5504.

    i submit a dual setup but its was plaset as singel setup.

    did need to edit it to dual setup

    OpenCL registers multiple cpus as a single device. Nothing much that can be done about that. Be sure to skip the CPU detection when submitting multi socket scores ... or edit the submission afterwards.
