This paper presents and validates performance models for a variety of high-performance collective communication algorithms for systems with Cell processors. The systems modeled in...
Although recent works try to improve collective communication in grid systems by separating intra and intercluster communication, the optimisation of communications focus only on ...
The venerable problem solving technique of simulation finds itself inthe midstof a revolution. Where once it was regarded as a "technique of last resort" for systems ana...
