Anybody knows about how pthread behaves in high contention and low contention situations? As far as I know, there is a unix-base policy (SCHED_OTHER) for mutex handling which optimizes the execution time in terms of contention. I want to know when pthread changes its policy from SCHED_FIFO to SCHED_RR and conversely. How does pthread detect the contention (threshold of changing the policy)?
