Hi Alex – As a rule of thumb, you shouldn’t expect to see full blown 100% use of the GPU. In the terrain computation the CPU and GPU take turns. In your plot, what is on the left, and what is on the right? What plots are you showing? What test is this for? How complex is it? It might not be able to saturate the GPU. What is the level of fidelity of the profiler that you use? Is this an NVIDIA profiler, like NVIDIA Nsight Compute? Dan --------------------------------------------- Bernard A. and Frances M.

From: [email protected] <[email protected]> On Behalf Of Alex Lan Sent: Saturday, July 8, 2023 11:50 PM To: ProjectChrono <[email protected]> Subject: [chrono] Can't fully use GPU Hi, I'm using FSI module to simulate terrain, but I found the GPU can't use fully. Is there any method to improve the usage of CUDA? The CUDA version is 12.0. I tried 11.7, but the usage of CUDA is also not full. Best regards.
