Thank you for your answer! I still don't understand since -np XX attributes job on logical processors (not on physical like you said). If I run 2 simulations at the same time using -np 10 for each, about 60% of cpu is used (20/40 = 50% plus 10% for my system). CPU usage always matches -np XX on total logical processors (40) and not physical processors (20).
Help me understand this please!
