Abstract
In this paper we discuss environments for the fullsystem simulation of multicomputers. These are composed of a large collection of modules that simulate the compute nodes and the network, plus glue elements that perform communication and synchronization. We present our own environment based on Simics and INSEE. We reuse as many Simics modules as possible to reduce the effort of hardware modeling, and simulate standard machines running unmodified operating systems. We explain how experiments reveal unforeseen interactions among all modules and components, providing results that are difficult to interpret. Another important issue is the synchronization among simulators: a trade-off has to be found between simulation speed and accuracy of results. 1.
