问题
In Linux there is a sched_setaffinity() function defined in sched.h, but I can't seem to find anything like that in Mac OS X 10.6 pthreads implementation... If it is not possible to set affinity, what is the default policy in OS X?
回答1:
Mac OS X has Thread Affinity API and you can use it with pthread ID as thread_policy_set(pthread_mach_thread_np(pthreadId), but, as far as I know, there are no APIs like sched_setaffinity.
