GpuTest / Re: GpuTest 0.7.0

« Last post by Stebs on March 09, 2014, 12:50:07 AM »

Hi, GpuTest seems to only support OpenGL Compatibility Profile and not the Core Profile.
This is a problem for all OpenSource (Mesa) OpenGL Drivers and probably also for all OS X Drivers (those also have only OpenGL Core Profile).
So, GpuTest reports only OpenGL 3.0, but with Intel Ivybridge (HD 4000), OpenGL 3.3 is possible in the Core Profile since some time now. Same is possible since very recently for Radeon and Nouveau Mesa Drivers.
Without using Core Profile, all those drivers will be limited to OpenGL 3.0

Output of GpuTest Log for the GiMark Test that does not work because OpenGL 3.3 Core Profile is not used:

General Discussion / Re: EVGA GeForce GTX 750 Ti FTW hands-on review

« Last post by Stefan on March 08, 2014, 10:02:59 PM »

EVGA GTX 750 Ti FTW BIOS Update (Reduced Fan Noise)

We now have an update available that will reduce the fan noise level while the card is idle. This update is ONLY for the EVGA GTX 750 Ti FTW model (with ACX Cooler), part number: 02G-P4-3757-KR. This update is already being applied to new cards that are shipping now.
 
The update to fan acoustics is the only change in this BIOS. Also please keep in mind it will not lower the minimum allowed fanspeed (42%), but the acoustic level will be lower. To update please follow the below instructions:
 

    Download the following .zip file: ftp://ftp.evga.com/bios/3757_Update.zip
    Extract the .zip file to a temporary location.
    It is recommended to UNINSTALL your NVIDIA display drivers.
    After display drivers are removed, run update.exe located in the folder that was extracted earlier.
    Reboot and reinstall the NVIDIA display drivers.

A successful flash procedure looks like this



If you don't uninstall GeForce driver a backup ends with an error and the system becomes unresponsive (i guess a flash will fail the same way, but i wasn't dumb enough to try)




Heads-up from GPUGrid

Just a line to say we've got our first GTX750Ti card up and running. The performance out-of-the-box matches a GTX480. We'll have a public app for GPUGRID just as soon as CUDA 6.0 is publicly released, which will probably happen at GTC at the end of the month.

GpuTest / Re: GpuTest 0.7.0

« Last post by JeGX on March 08, 2014, 10:53:21 AM »

But GpuTest is working now, yay!
If I use the (recommended) drivers, nvidia-319, it fails. But as you said,  most of them work well with Nouveau driver. TessMark's, GiMark and PixMark Julia FP64 aren't working, let me know if you want the log file for them.

It's normal, all these benchmark require OpenGL 3.3 or OpenGL 4.0 support and Nouveau driver is limited to OpenGL 2.1 or maybe 3.0 I can't remember.

I'm glad it works, and also saddened to get the results I feared...
I have a GTX 460 768mb, which is not bad I believe, and get 3-4 FPS on the FurMark test, 1024x640 windowed mode. Same with PixMark Volplosion: 3 FPS.

Same reason: Nouveau driver: Nouveau driver is slow and does not show the performance of your GTX 460. When you will manage to install real NV driver, you will see the difference. So don't panic, your GTX 460 is not dead

GpuTest / Re: GpuTest 0.7.0

« Last post by Pasqual on March 07, 2014, 06:36:37 AM »

Hey, thanks for the response!

I reinstalled Mint 16 to start fresh, because that's what I do when I screw up lol.
Unfortunetaly, I won't be able to share the log file because it's gone now... I reinstalled Mint before reading your post.
My PC wouldn't even boot up anymore, it would just get stuck on a black sreen before it reaches the desktop...
I probably ran too many random 'sudo' commands than I didn't understand xD! I'll stop doing that, it's probably a bad habit lol

But GpuTest is working now, yay!
If I use the (recommended) drivers, nvidia-319, it fails. But as you said,  most of them work well with Nouveau driver. TessMark's, GiMark and PixMark Julia FP64 aren't working, let me know if you want the log file for them.

I'm glad it works, and also saddened to get the results I feared...
I have a GTX 460 768mb, which is not bad I believe, and get 3-4 FPS on the FurMark test, 1024x640 windowed mode. Same with PixMark Volplosion: 3 FPS.

Now I know I'm completely off-topic, and I'll understand if I don't get an answer, but these results probably mean that my graphic card is broken, right? I bought it used.
I also tested with glxgears and I read that people get like 20 000 fps with my video card, but I only have 800-900...

Could there be any reason for such terrible results, other than my video card being physically damaged?

Hi Pasqual,

yes you've posted in the right forum.

Could you copy / paste the content of the log file (_geeks3d_gputest_log.txt) here? Maybe we'll see something interesting. The second thing you can do is to test the previous version of GpuTest:

http://www.geeks3d.com/20131028/gputest-0-6-0-opengl-benchmark-for-windows-mac-os-x-and-linux-downloads/

because I feel a possible bug with the new GPU monitoring plugin I added in GpuTest 0.7.0. By the way, can you delete plugin_gxl3d_gpu_monitor_gml_x64.so and plugin_gxl3d_opencl_x64.so and test GpuTest 0.7.0 again?

If I check ''Submit score to GPU database'', a webpage loads and I can read this in red : INVALID validation ID
Also, when I check this box, and only when I do, I get this message in the console:
(process:26770): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed

The GLib-CRITICAL message comes from firefox. Try the following command in a terminal:

$ firefox -v

and I'm sure you will have the same message.

I spent way too much time trying to install the latest NVIDIA drivers (I'm starting to miss Windows...) and I thought I had succeeded... maybe it didn't work, maybe that's why the test fails?

Totally agree with you. The installation of NVIDIA driver is easy and works fine in LM13 but is real pain in LM16. Try to use the Driver Manager to change / update the graphics driver. Most of GpuTest demos work fine with the Nouveau driver.

CUDA 6, Available as Free Download, Makes Parallel Programming Easier, Faster

We’re always striving to make parallel programming better, faster and easier for developers creating next-gen scientific, engineering, enterprise and other applications.

With the latest release of the CUDA parallel programming model, we’ve made improvements in all these areas.

Available now to all developers on the CUDA website, the CUDA 6 Release Candidate is packed with several new features that are sure to please developers.

A few highlights:

    Unified Memory – This major new feature lets CUDA applications access CPU and GPU memory without the need to manually copy data from one to the other. This is a major time saver that simplifies the programming process, and makes it easier for programmers to add GPU acceleration in a wider range of applications.
    Drop-in Libraries – Want to instantly accelerate your application by up to 8X? The new drop-in libraries can automatically accelerate your BLAS and FFTW calculations by simply replacing the existing CPU-only BLAS or FFTW library with the new, GPU-accelerated equivalent.
    Multi-GPU Scaling – Re-designed BLAS and FFT GPU libraries automatically scale performance across up to eight GPUs in a single node. This provides over nine teraflops of double-precision performance per node, supporting larger workloads than ever before (up to 512GB).

And there’s more.

The following are known issues with the CUDA 6.0 Release Candidate that will be resolved in the production release:
‣ The minBlocksPerMultiprocessor parameter for the launch_bounds() qualifier only accepts values up to 16 when used in compiling for sm_50, even
though values up to 32 are possible on that architecture.
‣ There is a performance issue with the new SIMD video intrinsics __v*2() and __v*4() when used in compiling for the sm_50 architecture.
‣ The sm_50 architecture supports 48 KB of shared memory per block; however, the check for this limit is not functioning properly in the compiler. This can allow
programs that use more than 48 KB of shared memory per block to compile successfully, although they will fail to run because the driver component does check
the limit properly.
‣ The MT19937 random number generator in the cuRAND library generates non-deterministic results for curandGenerateUniformDouble().
‣ The NPP library function nppiAlphaComp_8u_AC4R() generates incorrect results when used with the NPPI_OP_ALPHA_ATOP_PREMUL option.
‣ The NPP library functions FilterSobelHorizSecondBorder() and FilterSobelVertSecondBorder() may generate incorrect results.
