Low GPU usage when using TESLA K40 on HP Z620

[fracara]

Hi to all, I recently installed a tesla K40 together a quadro k600 on my Z620, but when I use particle simulation EDEM i see a low GPU usage, around 3%. Do I have to set something in the bios to enable GPU computing?

Thanks for your help.

I would contact the company that makes the software. The K40 and the K600 are old (2013) and many software companies has only full support for new hardware. For example, Adobe simply just dropped the support for old graphic cards since they don´t want to spend resources on old hardware.

Do you have an EDEM GPU license? This is additional to the EDEM license and is required for CUDA calculations using the GPU/compute cards.

According to the EDEM website;

9. How can I get access to EDEM GPU?

The EDEM GPU solver engine is directly integrated into the EDEM environment and activated by an add-on license token. Users can contact their Account manager to get started.

10. How do I go about using the GPU solver in my simulation?

Setting and running simulations with the EDEM GPU engine is as simple as enabling the GPU engine and then running EDEM the same way you would any other simulation. To get a step-by-step guide check our eLearning course: Introduction to EDEM 2019 – lessons 14.5 and 14.6 which explain how to use the GPU and multi-GPU solver engines.
