Query: Dynamically Improving Branch Prediction Accuracy Between Contexts   Branch prediction is a standard feature in most processors, significantly
improving the run time of programs by allowing a processor to predict the
direction of a branch before it has been evaluated. Current branch prediction
methods can achieve excellent prediction accuracy through global tables,
various hashing methods, and even machine learning techniques such as SVMs or
neural networks. Such designs, however, may lose effectiveness when attempting
to predict across context switches in the operating system. Such a scenario may
lead to destructive interference between contexts, therefore reducing overall
predictor accuracy. To solve this problem, we propose a novel scheme for
deciding whether a context switch produces destructive or constructive
interference. First, we present evidence that shows that destructive
interference can have a significant negative impact on prediction accuracy.
Second, we present an extensible framework that keeps track of context switches
and prediction accuracy to improve overall accuracy. Experimental results show
that this framework effectively reduces the effect of destructive interference
on branch prediction.
