In the 2.6 kernel, there is one run queue per CPU, in case of an SMP. After a thread is created, how does the scheduler determine which run queue it goes to? I know that once it goes to a particular run queue, the scheduler would try to run that thread on that CPU to take advantage of processor affinity; and then there would be the load balancing stuff. But at the very beginning, what algorithm does the scheduler use to assign a newly created thread to a particulat CPU? Would the load balancing algorithm be used? Or gang scheduling? By the way, in an SMT/hyperthreading processor, does the latest kernel version assign one run queue per physical CPU, or per virtual processor?
