Title:

NsimPower: Interconnect Simulator for Power and Performance Prediction

Abstract:

This talk introduces NsimPower which can be used for power-performance analysis of large scale interconnection networks. NsimPower was built based on a parallel discrete event simulation approach, and provides an MPI-compatible programming interface. It supports low-power idle behavior that attempts to turn active links off if no traffic appears. Therefore users can deeply analyze and understand the impact of such runtime power management on interconnect power-performnace characteristics. The power-performance profile generated by NsimPower can be fed to a visualization tool called Boxfish. This tool chain makes it possible for users to well understand the static (or steady-state) and dynamic (or transient) power behavior.
