Now I am doing simulation with reiforcement tool box by using GPU.
But, gpu usage can not become high.
I checked some points.
1, setting of gpu: gpu is connected to matlab.
2, It also declares ‘device’ and ‘gpu’.
But the usage doesn't go up, is there any other problem?

To get GPU utilization high you need to give it a lot of high resolution work to do. Often RL problems, especially the ones in our examples, are low compute. Not all computation is suitable for GPU parallelization.

Thanks to you, I was able to understand the GPU.
By the way, is there any way to shorten the simulation time?
