| Research Abstract |
A novel simulation method to provide right-weight and precise simulation for communication on distributed systems was proposed. We proposed a method which uses back-annotation technique which has been used for VLSI design. For back-annotation technique, the physical characteristics of the devices, such as delay and power consumption, will be measured and fed back to the simulation.
This technique enables to make the simulation result more precise. In this research, we first implemented a communication arbitrator modeling the physical communication arbitrator into a flow-based simulator, MFS (Message Flow Simulator). We also measured physical characteristics of an InfiniBand switches to obtain the data which will be annotated to the simulation. We compared all-to-all communication run on both simulator and actual super computer system.
