Hello all

I tested gpu acceleration, but it does not work. situtation is below.

*** FATAL ***

An error has occurred when trying to check for any GPU devices on machine .... Error code = 35 which translates to: CUDA driver version is insufficient for CUDA runtime version.

Please check your GPU device driver level and verify that a supported GPU device has been installed correctly.

GPU Acceleration: NVIDIA Library Requested but not Enabled

GPU Device with ID = 0 is:

GPU Driver Version: 9.10

************

Environment is below.

OS Platform: windows 10 64 bit

Video Adapter: 

1. Intel(R) UHD Graphics 630 (i disabled this device)

2. NVIDIA Tesla C2050

cuda runtime version and driver version are the same 9.1 by deviceQuery.

cuda: 9.1.85_win 10, nvidia driver: 390.85-tesla-desktop-win10-64bit-international

ANSYS product 2019R3 workbench

I set ANS_OVERRIDE=1, and cuda driver set to TCC mode.

but error has not gone, please let me overcome this error. thanks.

Open CMD Prompt, then issue the following command

"C:Program FilesNVIDIA CorporationNVSMInvidia-smi.exe"

then, post the screenshot of the output here.

Thanks,

Thanks for your reply.

output is below.

Thanks for the info.

Can you try this driver ?

I already tried that driver, but it couldn't install that driver.

As you know NVIDIA drivers are often fragile with like below error message.

so I tried other drivers which are able to install and cuda toolkits, but they also didn't work.

Please help me, thanks

That's very odd. Can you launch dxdiag and post screenshots of the first tab and the 'display' tab ?

[learner]

Yes.

[tsiriaks]

How did you disable the Intel graphics ? It's still using Intel by default. 

I'd recommend to try disabling Intel in the BIOS level, then try dxdiag again. It should show Nvidia this time. Then, try using ANSYS. (No need to try install the Nvidia driver at this time)

Thanks,

Win

I'm also trying to enable CUDA. Here's a screenshot.

Hi , 

I do have a similar problem.

I am using a NVIDIA GeForce RTX 2060 graphic cards.

I have read that even though it is not among the recommended graphic cards for the GPU acceleration it should anyway work.

Not as well as with a Quadro or Tesla card I presume but still.

I set up the environment variable ANSGPU_OVERRIDE to 1 .... still not enabling the library ...

Any idea ?
