Abstract
Systems and methods are provided that utilize non-shared page tables to allow an accelerator device to share physical memory of a computer system that is managed by and operates under control of an operating system. The computer system can include a multi-core central processor unit. The accelerator device can be, for example, an isolated core processor device of the multi-core central processor unit that is sequestered for use independently of the operating system, or an external device that is communicatively coupled to the computer system.
