Rapita Systems directors Antoine Colin and Guillem Bernat are co-authors of "Attacking the Sources of Unpredictability in the Instruction Cache Behavior", which will be presented at the 16th International Conference on Real-Time and Network Systems in Rennes, France on Oct 16-17th 2008.
The paper identifies the sources of cache-related variability, gauging them with ad-hoc experiments. Best-practice recommendations are made to attack these sources of unpredictability.
