CUDA error 35

Beatrice_M · April 2023

Hi everybody,

A few weeks ago I started using DualSPHysics, running quite simple simulations employing the macro DesignSHPhysics on freeCAD and using only the CPU, obtaining results in a reasonable time for 2D simulations with a few thousand of particles.

Since from now on I need to simulate 3D systems with more particles, I tried to run the same simulations as before on the GPU and I got this error message:

"*** Exception (../source/FunctionsCuda.cpp::GetCudaDevicesInfo:145)Text: Failed getting devices info. (CUDA error 35 (CUDA driver version is insufficient for CUDA runtime version))“ .

The workstation I am using is characterized by 64,0 GB RAM, Intel(R) Xeon(R) CPU E5-2690 0 @ 2.90GHz processor and Nvidia quadro A4000. Do I need to buy a new graphic card or this problem can be fixed keeping the one I have?

In case I need to buy a new graphic card do you have any suggestions for a powerful and suitable GPU with a budget of 1500 - 2000 € ? For example could NVIDIA RTX A4000 or one of the NVIDIA TESLA GPUs be good?

Thanks in advance

Beatrice

Hi

Please update your graphic driver.

That is what the error says; "CUDA driver version is insufficient for CUDA runtime version)"

The GPU you have is capable and you do not need to buy a new one. A little bit of help follows:

https://www.nvidia.com/download/find.aspx#

But otherwise find a youtube video explaining how to automatically download a geforce driver. Please note that while this should in theory never do anything bad to your system, I am not responsible if an unforeseen uncircumstance happens. This is quite a normal procedure though.

Kind regards

Thank you very much!

I'll try
