EFFICIENT PAGE OWNERSHIP CONTROL

摘要

Methods, systems and devices are described for efficient page ownership control. A method includes: providing a centrally-available record showing that a first process owns a memory page; recording in the centrally-available record a second process as owning the memory page; requesting ownership of the memory page by signaling the first process with the second process; then relinquishing control of the memory page by the first process by marking the memory page as not-owned in at least one control block that is private to the first process; then signaling the second process with the first process that ownership of the memory page is transferred; and then modifying the memory page with the second process. The methods, systems and devices provide advantages because the speed and scalability of parallel processor systems is enhanced.
