Figure 4 breaks down the expectation of page status for a newly arrived command: Open-Hit if the page is already open in the corresponding bank; Open-Miss if there’s an open page which is not the right one (which will impose a Precharge-Activate sequence to get the right page); and Closed if there’s no open page at that bank’“i.e., the scheduler has preemptively precharged a page, probably in an attempt to save time the next time a page needs to be activated. Evidently, FR-FCFS, which is an open-page algorithm, simply does not expect to find a closed page in steady state. On the other hand, the self-optimizing configurations Ipek and MORSE-P do precharge pages proactively if they predict a long-term benefit. The plot shows that MORSE-P is in fact superior to FR-FCFS and Ipek, in that the expectation of Open-Hit is highest almost universally. This increased hit rate correlates well with bottom-line performance in many applications.
