摘要： Dynamic control of memory affinity is provided for a shared memory logical partition within a shared memory partition data processing system having a plurality of nodes. The memory affinity control approach includes: determining one or more home node assignments for the shared memory logical partition, with each assigned home node being one node of the plurality of nodes of the system; determining a desired physical page level per node for the shared memory logical partition; and allowing the shared memory partition to run and using the home node assignment(s) and its desired physical page level(s) in the dispatching of tasks to physical processors in the nodes and in hypervisor page memory management to dynamically control memory affinity of the shared memory logical partition in the data processing system.

摘要： In an embodiment, a target number of discretionary pages for a first partition is calculated as a function of a number of physical page table faults, a number of sampled page faults, a number of shared physical page pool faults, a number of re-page-ins, and a ratio of pages. If the target number of discretionary pages for the first partition is less than a number of the discretionary pages that are allocated to the first partition, a result page is found that is allocated to the first partition and the result page is deallocated from the first partition. If the target number of discretionary pages for the first partition is greater than the number of the discretionary pages that are allocated to the first partition, a free page is allocated to the first partition.

摘要： Hypervisor page fault processing logic is provided for a shared memory partition data processing system. The logic, responsive to an executing virtual processor of the shared memory partition data processing system encountering a hypervisor page fault, allocates an input/output (I/O) paging request to the virtual processor from an I/O paging request pool and increments an outstanding I/O paging request count for the virtual processor. A determination is then made whether the outstanding I/O paging request count for the virtual processor is at a predefined threshold, and if not, the logic places the virtual processor in a wait state with interrupt wake-up reasons enabled based on the virtual processor's state, otherwise, it places the virtual processor in a wait state with interrupt wake-up reasons disabled.

摘要： Relocating data in a virtualized environment maintained by a hypervisor administering access to memory with a Cache Page Table (‘CPT’) and a Physical Page Table (‘PPT’), the CPT and PPT including virtual to physical mappings. Relocating data includes converting the virtual to physical mappings of the CPT to virtual to logical mappings; establishing a Logical Memory Block (‘LMB’) relocation tracker that includes logical addresses of an LMB, source physical addresses of the LMB, target physical addresses of the LMB, a translation block indicator for each relocation granule, and a pin count associated with each relocation granule; establishing a PPT entry tracker including PPT entries corresponding to the LMB to be relocated; relocating the LMB in a number of relocation granules including blocking translations to the relocation granules during relocation; and removing the logical addresses from the LMB relocation tracker.

摘要： A method of providing a substrate with a decorative coating simulating the appearance of grained wood. A continuous layer comprising an aqueous medium which contains a polymeric binder and a particulate, non film-forming material is applied to an opaque surface of the substrate (the particulate material and the resulting layer both being lighter in color than the opaque surface. While the layer remains in the liquid state, a tool having a longitudinal extending face which has a convex section transverse to the longitudinal direction thereof, is drawn along the layer, the face of the tool having a series of spaced ridges along the longitudinal direction. The tool is rocked about the face as the tool is drawn along the layer, so as to discontinuously remove parts of the layer and selectively expose part of the underlying surface and to produce a decorative appearance resembling heart grains of cut timber.
