I decided to run GIMPS for a little while on my home PC with an i7 CPU just to get the project in my Free-DC stats to feed my silly need to have as many projects as possible listed there. I downloaded Prime95 and linked it to my GIMPS ID and told it to run and choose whatever work seems best. It is running, but even though I told it to use all 4 cores plus HT, it's only actually using the four physical cores and the HT cores are showing pretty much zero usage in Task Manager.
Is that normal, or am I missing something to get it to use all 8 "processors"? If I try to change the 4 cores to 8 in the Worker Windows option on the file menu, it just changes back to 4 again as soon as I click OK. It does this whether the process is actively running or if it is stopped (paused).
