Abstract: HP Lab's COTSon is a full system simulation framework based on AMD's SimNow. COTSon allows for simulating complete computing systems, ranging from a single node to a large cluster of hundreds of multicore nodes. This paper is the result of the first six months of the collaboration project between HP Labs and the Universitat Aut*onoma de Barcelona, in which network simulation under COTSon is explored in order to then propose and implement network topologies. The ultimate goal is to be able to perform reliable and accurate networking simulations using COTSon. This report explains how to configure COTSon to perform network simulations, and describes the different steps to run a parallel application and obtain performance results. Results shown in this paper were carried out in 2007, with the versions of COTSon and SimNow available at that moment. Some of the configurations and steps described here may have changed since then.
