Lock contention aware thread migrations
2014
Proceedings of the 19th ACM SIGPLAN symposium on Principles and practice of parallel programming - PPoPP '14
On a cache-coherent multicore multiprocessor system, the performance of a multithreaded application with high lock contention is very sensitive to the distribution of application threads across multiple processors. This is because the distribution of threads impacts the frequency of lock transfers between processors, which in turn impacts the frequency of last-level cache (LLC) misses that lie on the critical path of execution. Inappropriate distribution of threads across processors increases
