Abstract :
Recently, Time Warp has shown that it achieves good strong scaling to hundreds of thousands of processors on modern supercomputer systems. These results were achieved on the Cray and IBM Blue Gene supercomputing platforms. In this paper, we investigate the ROSS Time Warp cache memory performance on (i) a commodity shared-memory desktop system based on the Intel E5504 processor and (ii) the IBM Blue Gene/L when configured to run over the standard Message Passing Interface (MPI) library.
