Abstract
This technical report presents the MRSG simulator for MapReduce platforms. The simulator’s goal is to serve as a research tool, and assist in the development of new approaches and solutions to MapReduce platforms. It is described, as well, the decisions made in the simulator’s model, MRSG’s architecture, and the current development state. An initial validation shows the current precision of the already implemented features, in comparison to real executions of the Hadoop MapReduce platform.
