Threadripper 3990x

Hi, i have a Threadripper 3990x with 64gb of ram and i notice that only 64 of the 128 threads are used when using pix4d mapper for steps 1 and 2. is there a way to use all the threads or just be happy with 64 threads. I also notice that the CPU hits 60-65% utilization and the GPU only gets up to 10%.

I’m trying to make a high speed system but not really seeing it. Any way to help?

Thanks
