Fine tune gtx 2080 on Ubuntu?


I just install a GTX2080/8GB on Ubuntu. When a ran a program on Pytorch, I saw that in the nvidia-smi, the usage of the GPU is about 3-4% most of the time? The program took about 25 mins to finish.

Just wonder if if it possible to boost the GPU usage/memory to say 60 or even higher in order to shorten the run time? If yes, any guideline available?

I have a AMD amd ryzen 7 3700x, SSD and 32G RAM.
