Burn in Test with Tesla GPUs

[H in OH]

Does BurnInTest also exercise Nvidia Tesla GPUs to full power?
You won't get a fair test of system heat if included calculation engine GPUs are not brought up to full power along with the CPUs.

Thanks.

In V7 of BurnInTest there is a 3D test that can be run.
While this will load the card, we can't say for sure if this will bring it up to it maximum running temperature.

We are looking at including a new series of OpenCL / DirectCompute tests into the next major release of BIT (this will be V8. These will definitely have the potential to put a lot of load on the GPU.

If you are interested in beta testing, please let me know.

Just tried BIT 8.0 with the new GPGPU tests. An NVIDIA Quadro card in the system was tested, but installed Nvidia Tesla cards do not appear under test. BIT seems to ignore Nvidia GPUs that are in TCC mode for pure computation and only tests those under WDDM mode for video output.

Could you please turn on level 2 activity trace logging (see Preferences->Logging), run the GPGPU test for 1 minute and send us the *.trace file showing the test run, to:

Just adding this as a note for future searches, when a Tesla card is in TCC mode (with no graphical output) it only supports CUDA applications and doesn't support DirectX, Vulcan or OpenGL applications. BurnInTest will not be able to see and test that cards if they are in TCC mode.

Is there any reason that a CUDA test cant be added to Burn In Test? We sell a lot of products that contain Tesla cards, and we cant test them currently because BIT does not support it..

[David (PassMark)]

The GPGPU test uses DirectX (DirectCompute to be exact).

Yes, from a technical point of view CUDA could be added. But BurnIntest for Windows is (unsurprisingly) Windows software. As such we expect video cards to support DirectX, as it is the Windows industry standard, with OpenCL being the 2nd choice and maybe Vulcan as the 3rd. If you really need CUDA we would be happy to look at doing it as custom development.

To clarify, we currently need to test the Nvidia Tesla V100 cards and the current GPGPU test fails to recognize these cards. We also have a specific need to run in 64-bit only mode as some of the systems we are testing are diskless and require us to use WinPE. An OpenCL based GPGPU test would be great as we would be able to test these cards and it would also work on ATI based cards.

DirectX is the standard for GPU acceleration on Windows. If a card doesn't support DirectX, then it is a really niche (and a small market). Not all cards support OpenCL. Mainly due to missing device drivers. So that isn't a great general solution either.

So for the moment only DirectCompute is supported. If you really need CUDA (or OpenCL) we would be happy to look at doing it as custom development. Or we might eventually look at it for a future release if cards are still being produced without DirectX support.
