How about muti-core? Does each core also have its own run queue? Does anyone know how multi-core would work with SMT? Is it possible that they work together? Is the following a possible scenario? : A node has two processors, each processor has two cores, and each core has two "virtual cores". And there are 8 run queues in total.
