Abstract |
In this paper, a novel approach is proposed, so this article deals with the issues of increasing the efficiency of computations in multicore computer systems due to the application of fine-grained parallelism.in general, This approach based on mixed parallelism and the proposed approach is based on medium-grained and fine-grained that using to increasing Kp the effectiveness and permissions of mixed parallelism to increase Kp using C and the OpenMP library tools. At the same time, the parallel program includes a set of traditional streams on the number of MCS cores. Each of these streams further implements internal (fine-grained) parallelism by creating sub-streams with appropriate Fork-Join tools. The initial number of traditional streams can be reduced to ensure fine-grained parallelism with free processor resources. The results shows the effectiveness by using this approach based on mixed parallelism to increase Kp when used in C and the OpenMP library. At the same time, there is an increase in Kp with an increase in the volume of processed data, which is one of the most important arguments of the expediency of this approach in the MCS. It can be assumed that the effectiveness of using mixed parallelism will be increase with increasing number of cores in MCS |
