Find number of cores per processors (Oracle consider threads to be cores, when estimating for example cpu_count)
smtctl This system is SMT capable. This system supports up to 4 SMT threads per processor. SMT is currently enabled. SMT boot mode is not set. SMT threads are bound to the same virtual processor. proc0 has 4 SMT threads. Bind processor 0 is bound with proc0 Bind processor 1 is bound with proc0 Bind processor 2 is bound with proc0 Bind processor 3 is bound with proc0 proc4 has 4 SMT threads. Bind processor 4 is bound with proc4 Bind processor 5 is bound with proc4 Bind processor 6 is bound with proc4 Bind processor 7 is bound with proc4 proc8 has 4 SMT threads. Bind processor 8 is bound with proc8 Bind processor 9 is bound with proc8 Bind processor 10 is bound with proc8 Bind processor 11 is bound with proc8 proc12 has 4 SMT threads. Bind processor 12 is bound with proc12 Bind processor 13 is bound with proc12 Bind processor 14 is bound with proc12 Bind processor 15 is bound with proc12 proc16 has 4 SMT threads. Bind processor 16 is bound with proc16 Bind processor 17 is bound with proc16 Bind processor 18 is bound with proc16 Bind processor 19 is bound with proc16
