Adaptive Memory Management and Optimism Control in Time Warp

  title={Adaptive Memory Management and Optimism Control in Time Warp},

  journal={ACM Trans. Model. Comput. Simul.},
It is widely believed that the Time Warp protocol for parallel discrete event simulation is prone to two potential problems: an excessive amount of wasted, rolled back computation resulting from “rollback thrashing” behaviors, and inefficient use of memory, leading to poor performance of virtual memory and/or multiprocessor cache systems. An adaptive mechanism is proposed based on the Cancelback memory management protocol for shared-memory multiprocessors that dynamically controls the amount of… CONTINUE READING
