Simulation of MPI applications with time-independent traces
Analyzing and understanding the performance behavior of parallel applications on parallel computing platforms is a long-standing concern in the High Performance Computing community. When the targeted platforms are not available, simulation is a reasonable approach to obtain objective performance indicators and explore various hypothetical scenarios. In the context of applications implemented wi...
متن کاملNetwork Simulation on Cray-T3E using MPI
We propose a novel approach for parallel discrete-event network simulation on packet-switched, point-to-point networks. Our algorithm resolves packet connicts through priority sorting of appropriate integer connict functions. We implement our method on CM-5, Cray-T3D, and Cray-T3E systems using C and MPI, and perform critical optimizations aimed at reducing sorting overhead, minimizing inter-pr...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Toward Better Simulation of MPI Applications on Ethernet/TCP Networks
Simulation and modeling for performance prediction and profiling is essential for developing and maintaining HPC code that is expected to scale for next-generation exascale systems, and correctly modeling network behavior is essential for creating realistic simulations. In this article we describe an implementation of a flow-based hybrid network model that accounts for factors such as network t...
متن کاملCellular Automata as Acceleration Kernel of Interconnection Network Simulation
Drastic growth in the number of processor cores in state-of-the-art supercomputers is increasing difficulties in discussing and designing efficient architectures. One of the toughest problems is interconnection network (ICN) architecture that is severely responsible to both performance and costs. For the coming exa-scale supercomputers and beyond, a significant breakthrough is expected in discu...
