Run Code_Saturne on GPU

Post by Ruonan »

Dear developers,

Could you please help me with this question?

Currently my CPU resources are limited but I have some GPUs available. So I'd like to know if I can take advantage of GPU.

I can see some posts saying that it may not be a good idea to use GPU, but it's a few years ago. Do you have any experience with this recently? For running on GPU, is it easy to achieve much higher performance? Is it easy to do it or do I need to do much work on my side? I run LES with a mesh size of about 10~20 million nodes.

Thank you very much,
Ruonan

Hello,

As of today, only a part of some linear solvers may be run on GPU, which is not enough to provide you an increase in performance.

We are working on GPU support, but it is not ready yet...

Best regards,

Yvan
