System config: Win 7 64bit, visual Studio 2010 Premium, dell t7500 with 2 xeon 5690 chips, 48 gig of ram. Each xeon has 6 cores, so there are 12 physical cores. With hyperthreading, there should be 24 logical cores.
In my C app:
Session.coresAvailable = omp_get_num_procs ( );
Session.threadsAvailable = omp_get_max_threads ( ) ;
The system comes back and tells me there are 12 cores and 12 threads. Shouldn’t it be 24 threads?
Converting comment to answer:
You need to enable HyperThreading in the BIOS to see all 24 threads.
