- W2894449746 abstract "Over the last years, high performance computers (called clusters) have been used to manage with really complex tasks as to make weather predictions, to run physics simulations and to perform medical researches. Following the Moore’s law, the number of cores in the clusters increased significantly until now, where the biggest cluster platforms contain enormous number of cores and have the capability of solving complex problems in a few minutes. The main usage of such massively parallel processing machines is to achieve a performance as high as possible, which depends not only on the hardware architecture model but the used software has also an impact on the performance. In this paper, the performance and scalability of the unified MPI-2 model are compared with the hybrid model of MPI-2 with OpenMP implementation using the high-performance computing system Avitohol [1]. Intel benchmark tests are used: ping-pong operations and one-sided communication [2]. The range of the patterns is from light to heavy communication traffic: point-to-point message passing and shared memory programming. This research discovers the potentials in developing high performance parallel codes on the high-performance computing system “Avitohol”." @default.
