Simulation of the algorithms for optimization of remote core locking method for multicore computer systems

摘要

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.
