I’m using Jetson AGX Orin 64GB which shows in the specifications it has 12 CPU cores. However, when i’m monitoring the cpu resources in power GUI i noticed only 8 cores reach to 100% when i’m running few codes while the other 4 are always 0%. Also, system monitor shows only CPU0-7.
Which jetpack version is in use?
Could you share me the dmesg and sudo tegrastats result?
This is a CPU section of the dmsg. Remapping and enabling EFI services.

it reads 12 CPUs but i’m not sure why system monitor and PowerGUI only consider 8 and the other 4 as offline
Could you run sudo nvpmodel -m 0 again and see if cpu cores are all enabled or not?
