SCALABLE VIRTUAL MEMORY METADATA MANAGEMENT
20210109772 · 2021-04-15 ·

Scalable virtual memory metadata management comprising a plurality of pre-instantiated VM metadata containers representing the entire amount of real physical memory available to a computing system, with additional instantiated VM metadata containers created as needed. Individual and/or groups of VM metadata containers are assigned to metadata container groups, wherein each container group is controlled by an acquired lock assigned to the VM metadata container groups. Virtual memory metadata is managed using a “least used” technique. In response to allocation requests, the allocator scans the container groups/VM containers and fulfills memory object metadata allocation to the least used VM metadata container of the least used container group, filling the individual VM metadata containers and/or the container groups at a nearly equal rate.

Medical drape having an ultra-thin drape film and a thick adhesive coating

A system for treating a tissue site includes a pressure source to apply reduced pressure, and a manifold in fluid communication with the pressure source to provide reduced pressure to the tissue site. The system includes a drape for adhering to the tissue site to cover the tissue site and the manifold. The drape has a film layer having a thickness less than about 15 microns, and an adhesive coupled to the film layer. The adhesive seals the film layer to the tissue site to create a sealed space having the manifold therein. The adhesive is sufficiently thick to limit leaks between the film layer and the tissue site.
