Parallel Simulation Systems: Adaptive Mechanisms

Adaptive mechanisms for parallel simulation

This work is examining adaptive synchronization protocols that monitor the execution of the parallel simulator, and automatically adapt the simulator's execution to optimize performance. Adaptive mechanisms allow the underlying simulation system to achieve maximum performance, particularly for dynamically changing workloads that often arise in practice. These mechanisms can also simplify the development of parallel simulation software to the extent that some degree of performance ``tuning'' is automatically performed by the simulation system, rather than by the application programmer, who may not be an expert in parallel simulator performance. A protocol that uses memory allocation to control execution has been developed and evaluated.
