Modeling of Single Computing Nodes of Parallel Computers
Peter Hanuliak · American Journal of Networks and Communications · 2014
The paper describes analytical modeling for single computing nodes of parallel computers. At first the paper describes very shortly the developing steps of parallel computer architectures and then he summarized the basic concepts for performance evaluation. To illustrate theoretical evaluation concepts the paper considers in its experimental part the achieved results on concrete analyzed examples and their comparison. The suggested analytical models consider for single computing node based on processor or core and SMP modeling of own computer node´s activities and node´s communication channels of performed data communications within computing node queuing theory systems M/D/m or M/D/. In case of using SMP parallel system as node computer the suggested models consider for own node’s activities M/M/m or M/D/m queuing theory systems. Although we are able to use other more complicated queuing theory systems we prefer modeling with mentioned models because achieved results for these models we can use in decomposed modeling of coupled computing nodes as network of workstations (NOW) or network of massive NOW modules (Grid). The achieved results of the developed analytical models we have compared with the results of tested computing nodes with other alternative evaluation method based on suitable benchmarks to verify developed analytical models. The developed analytical models could be used under various ranges of input analytical parameters, which influence the architecture of analyzed computing nodes which are interested for the praxis.
