Abstract
A system that includes a memory, a tilelet data structure entry, a first tile freelist, and an allocation subsystem. The memory includes a first tilelet on a first tile. The tilelet data structure entry includes a first tilelet preferred pagesize assigned to a first value. The first tile freelist for the first tile includes a first tile in-bounds page freelist, and a first tile out-of-bounds page freelist. The allocation subsystem is configured to detect that a first physical page is freed, store, in the first tile in-bounds page freelist, a first page data structure, detect that a second physical page is freed, store, in the first tile out-of-bounds page freelist, a second page data structure, and coalesce the memory using the second page and at least one of the physical pages associated with the plurality of out-of-bounds page data structures into a third physical page.
