Resumo

The paper presents some test results of the heterogeneous computing cluster HybriLIT put into operation at the Laboratory information technologies of the Joint Institute for Nuclear Research. The structure of the cluster includes computational nodes with NVIDIA graphical accelerators and Intel Xeon Phi coprocessors. The necessity of integration of such a computational platform in the JINR Multifunctional Information and Computing Complex is determined by a global tendency to use hybrid computing architectures for carrying out massive-parallel computations in applied scientific problems solution. Test of the cluster aimed at: first of all, test of the efficiency of hardware and software settings that include operational system, resource manager, file system, compilers, and, secondly, test of the efficiency of using different architectures for the solution of particular applied problems in order to provide user guides on specialized libraries. For realization of the cluster test, an approach that includes test computations by means of standard program packages such as Linpack and program complexes established in LIT has been developed. The presented results show that the use of hybrid computing architectures allow accelerate the solution of applied scientific problems, and heterogeneous computing cluster HybriLIT is an effective means of accomplishing this aim.
