Optimized Parallel Discrete Event Simulation (PDES) for High Performance Computing (HPC) Clusters
Nael Abu‐Ghazaleh · 2005
The aim of this project was to study the communication subsystem performance of state of the art optimistic simulator Synchronous Parallel Environment for Emulation and Discrete-Event Simulation (SPEEDES) and explore approaches for accelerating it. The primary focus has been on system level improvements; specifically, a primary goal was to explore the performance of the simulator on a cluster with a Myrinet network. Myrinet provides several features conducive to the success of parallel simulation: it provides a high bandwidth, low latency network, with user level network protocol (avoiding the Operating System overhead) and provides some processing on the network interface card to reduce the load on the host processor. In addition, algorithmic improvements to the communication susbsystem were considered.
