Abstract:
A thread on one processor may be used to enable another processor to lock or release a mutex. For example, a central processing unit thread may be used by a graphics processing unit to secure a mutex for a shared memory.
Abstract:
Page faults arising in a graphics processing unit may be handled by an operating system running on the central processing unit. In some embodiments, this means that unpinned memory can be used for the graphics processing unit. Using unpinned memory in the graphics processing unit may expand the capabilities of the graphics processing unit in some cases.

Abstract:
In one embodiment, the present invention includes a multicore processor with first and second groups of cores. The second group can be of a different instruction set architecture (ISA) than the first group or of the same ISA set but having different power and performance support level, and is transparent to an operating system (OS). The processor further includes a migration unit that handles migration requests for a number of different scenarios and causes a context switch to dynamically migrate a process from the second core to a first core of the first group. This dynamic hardware-based context switch can be transparent to the OS. Other embodiments are described and claimed.
Abstract:
A processor of an aspect includes an instruction pipeline to process a multiple memory address instruction that indicates multiple memory addresses. The processor also includes multiple page fault aggregation logic coupled with the instruction pipeline. The multiple page fault aggregation logic is to aggregate page fault information for multiple page faults that are each associated with one of the multiple memory addresses of the instruction. The multiple page fault aggregation logic is to provide the aggregated page fault information to a page fault communication interface. Other processors, apparatus, methods, and systems are also disclosed.
