Optimization of thread affinity and memory affinity for remote core locking synchronization in multithreaded programs for multicore computer systems

This paper proposes the algorithms for optimization of Remote Core Locking (RCL) synchronization method in multithreaded programs. The algorithm of initialization of RCL-locks and the algorithms for threads affinity optimization are developed. The algorithms consider the structures of hierarchical computer systems and non-uniform memory access (NUMA) to minimize execution time of RCL-programs. The experimental results on multi-core computer systems represented in the paper shows the reduction of RCL-programs execution time
