    Abstract: Methods and apparatuses pertaining to dynamic memory sharing may involve sharing a first portion of a memory associated with a first module for use by a second module. The first portion of the memory may be reclaimed for use by the first module in real time upon a determination that there is an increase in demand for the memory by the first module that requires reclamation, such that the first module begins to use the first portion of the memory before the second module finishes a process of aborting to use the first portion of the first memory.

    Abstract: An efficient, on-demand, content-based memory sharing method is performed by a system. The method begins when an event is detected. The system predicts a merge gain based on a current number of candidate pages in the memory, a current number of merged pages, and a merge ratio which represents a merged-to-candidate page ratio. In response to a determination that the merge gain is greater than a threshold, the system performs a scan and merge operation to merge a set of the candidate pages, which have a same content and have not been merged, into a single page having the same content.

    Abstract: Techniques and implementations pertaining to a heterogeneous swap space with dynamic thresholds are provided. A technique may provide a list of a plurality of swap areas in a heterogeneous swap space. The swap areas may include at least two swap areas that are different from each other in one or more characteristics. The technique may also compute a dynamic threshold associated with a page in need of swapping and determine a priority level of the page in need of swapping based on the dynamic threshold. The technique may further select one of the swap areas from the list of swap areas for the swapping of the page in response to a determination of the priority level of the page.
