摘要:
Disclosed Methods, Apparatus, and articles of manufacture to profile page tables for memory management are disclosed. An example apparatus includes a processor to execute computer readable instructions to: profile a first page at a first level of a page table as not part of a target group; and in response to profiling the first page as not part of the target group, label a data page at a second level that corresponds to the first page as not part of the target group, the second level being lower than the first level.

Embodiments of the present invention provide a method, system and computer program product for dynamic main memory reconfiguration in virtual memory management. In an embodiment of the invention, a method for dynamic main memory reconfiguration in virtual memory management can include receiving a memory access directive in a host computer, determining a low free space condition in a memory allocation to satisfy the memory access directive, augmenting the memory allocation with a mapping to additional memory in the host computer in lieu of page swapping in response to the low free space condition, and satisfying the memory access directive. Additionally, the method can include determining an excess free space condition in the memory allocation and removing from the memory allocation a selection of allocated memory in the host computer.
摘要:
Provided are techniques for parsing source code file into a plurality of functions; generating a ranking corresponding to each of the plurality of functions based upon an order of occurrence in the source code file; generating a weight score corresponding to each of the plurality of functions based upon a weighing factor and the occurrence of a condition corresponding to each of the plurality of functions; and generating an object code file such that the plurality of functions are ordered in the object code file based upon the corresponding rankings and weight scores such during a startup of execution of the object code file a startup time is minimized with respect to an object code file not generated in accordance with the claimed method.
