This paper proposes an adaptive invalidate/update protocol for software distributed shared memory(DSM), which use the working-set notion of a conventional operating system as the criteria for determining whether to update or invalidate. The proposed protocol can adjust the amount of update messages as changing the value of working-set size. The proposed protocol was implemented in CVM[4], a sof...

Two-level predictors improve branch prediction accuracy by allowing predictor tables to hold multiple predictions per branch. Unfortunately, the accuracy of such predictors is impaired by two detrimental effects. Capacity misses increase since each branch may occupies entries proportional to the number of different path histories leading up to the branch. The working set of a given program ther...
