How can I speed up my simulation

Shadi · May 2023

Dear DualSPHysics user,

I am running a case (NNDambreak 3D) with 2.5 million particles using GPU mode. However, I have noticed that in my task manager, only 16% of CPU and 0% of GPU capacity are being utilized during the simulation. I am seeking suggestions on how to increase the CPU and GPU capacity usage in order to speed up my simulation.

The GPU I am using is the NVIDIA P2200.

Any suggestions and help would be greatly appreciated.

Hi,

Task manager sometimes gives wrong info on GPU usage. Have you tried to use other tool such as: GPU-Z

Thank you so much Pouzol.

I am not quite sure I understood what you are referring to when you mention GPU-Z.

I ran a case with 2.5 million particles and it toke me 4 days. So do you think in this case also the task manager shows wrong info?

Best,

Shadi

Hi,

GPU Z is a software that monitor GPU usage (free)
