COOPERATIVE MODEL FOR OPTIMIZATION OF EXECUTION OF THREADS ON MULTI-CORE SYSTEM
Abstract
The problem of the increase of efficiency of multi-thread applications on multi-core systems is investigated. The optimization cooperative model of threads execution has been proposed. It optimizes the execution order of the computational operations and the operations of data exchange, decreases the overall time of the multithread application execution by means of the reduction of the critical path in the concurrent algorithm graph, increases the application throughput at the growth of the number of threads, and excludes the competition among threads that is specific for preemptive multitasking...............................
