How to make the program use the GPU as much as possible?

I am using GPU to run this program, but the GPU usage is very low. How can I increase the GPU usage to make the program execute faster? What settings in the code need to be changed to make the best possible use of the GPU? 谢谢您

The issue names no files, tests, entry points, or GPU settings to inspect. Start by locating the program's training or simulation entry point and profiling a GPU run; completion would require identifying an actionable configuration or code change and demonstrating faster execution or higher utilization.
