I have a dual 12-core, 24-thread system. MATLAB, for some reason, is only fully utilizing one of the CPUs. It spawns 24 threads, but all of them seem to run on a single CPU.
Ideally, I would expect either:
  • 12 threads per CPU (24 threads total), or
  • 24 threads per CPU (48 threads total, if MATLAB scales that way),
but not 24 threads on one CPU.
I’ve attached a screenshot showing the CPU usage. Can anyone please help me understand why this is happening and how to fix it so MATLAB properly distributes threads across both CPUs?
