Challenges in Multicore Performance Predictions

Software performance predictions are an established part of an engineering like software development process and therefore relevant to enable high quality and to ensure requirement fulfillment. Software Performance Engineers use for that model-based performance predictions approaches. However, current predictions approaches are based on the assumption of single core CPU systems. To enable Software Performance Engineers to further give accurate predictions also for multicore systems, which are by now state of the art, we need to adapt our current prediction models. On the poster, we discuss the upcoming challenges to be tackled to increase the accuracy of the performance predictions models.
