I'm running helloworld_epoll, I want to test its performance on a large number of cores. Maybe I'm doing something wrong, could someone please tell me? As you can see I set the mask in the config and dpdk sees 24 lcores but I don't see where it initializes them, it's like there is only one core with the mask number.
