Hi 

maybe the GENGA code by Joachim Stadel at UZH is something for you.

Hi Alfio,
Yes, that's what I mean. So is there any use case where the kernels can run for longer? Thanks.

Hello Max,
I'm not sure I understand your point 1). Do you mean 30 minutes for a single kernel to run on the GPU? If so, no, we don't have such a case. We do matrix-matrix multiplications and there will be not enough data to run for 30 minutes...

Hi,
I'm doing research in the area of High-Performance computing, specifically
to do with the resilience of GPUs for long-running applications.

The GPU technology I focus on is CUDA.

I found the cp2k noticed that it has support for CUDA.

And have a few questions:
1. Can any simulations cause cp2k CUDA kernels to run for a long time continuously?  (anything around or over 30 minutes)
2. If not, do you know of any CUDA applications that have long-running kernels?

Thanks.
