        Description

        Currently the make file setup on AIX determines the NUM_CORES based on the AIX physical processors. However, better performance can be leveraged on SMT enabled AIX machines. From my testing build times up to 30% quicker.
        Querying the LCPUs via 'pmcycles -m' can be used on both SMT and non-SMT enabled AIX machines.
