This paper described recent improvements to the Graphite simulator designed to help explore current and emerging research topics. With these improvements, Graphite is ideally suited to explore both power and performance in future multicore and manycore processors, especially those incorporating dynamic runtime monitoring and adaptation. Separate validation of Graphite has shown performance results within about 6% on average (18% worst case) of a cycle-level simulator and normalized power trends are predicted to within 10%. This makes Graphite accurate enough for medium- to long-term studies while maintaining very high performance. Graphite is freely available for anyone to use: http://graphite.csail.mit.edu.
