We are running an application with (currently) the non-cluster PARDISO under Windows Server 2012 SP1, the machine is a HP DL980 with 160 logical cores (80 cores with HT turned on) and 2TB RAMs. We are having problems in utilizing all cores, most likely originated from the Windows "Core Group" limit of 64 cores each. I am happy to see now Intel offers the clustered version of PERDISO in MKL. Can this new version now handle multiple core groups as clusters of computers? Any special configuration requirement to use the new PARDISO? Or we have to reconfigure the machines with the clustering SW? Do I need to update my Fortran Composer license to the Clustered edition, or an update of current professional edition will do?
