Abstract
Systems, methods and media for selectively closing pages in a memory in anticipation of a context switch are disclosed. In one embodiment, a table is provided to keep track of open pages for different processes. The table comprises rows corresponding to banks of memory and columns corresponding to cores of a multi-core processing system. When a context switch signal is received, the system unsets a bit in a column corresponding to the core from which the process is to be context-switched out. If no other process is using a page opened by the process the page is closed.
