20110161619 | SYSTEMS AND METHODS IMPLEMENTING NON-SHARED PAGE TABLES FOR SHARING MEMORY RESOURCES MANAGED BY A MAIN OPERATING SYSTEM WITH ACCELERATOR DEVICES - 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. | 06-30-2011 |
20110161620 | SYSTEMS AND METHODS IMPLEMENTING SHARED PAGE TABLES FOR SHARING MEMORY RESOURCES MANAGED BY A MAIN OPERATING SYSTEM WITH ACCELERATOR DEVICES - Systems and methods are provided that utilize 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. | 06-30-2011 |
20120188259 | Mechanisms for Enabling Task Scheduling - Embodiments described herein provide a method including receiving a command to schedule a first process and selecting a command queue associated with the first process. The method also includes scheduling the first process to run on an accelerated processing device and preempting a second process running on the accelerated processing device to allow the first process to run on the accelerated processing device. | 07-26-2012 |
20120198458 | Methods and Systems for Synchronous Operation of a Processing Device - Embodiments of the present invention provide a method of synchronous operation of a first processing device and a second processing device. The method includes executing a process on the first processing device, responsive to a determination that execution of the process on the first device has reached a serial-parallel boundary, passing an execution thread of the process from the first processing device to the second processing device, and executing the process on the second processing device. | 08-02-2012 |
20120200576 | Preemptive context switching of processes on ac accelerated processing device (APD) based on time quanta - Methods, systems, and computer readable media for preemptive context-switching of processes on an accelerated processing device are based upon a comparison of the running time of the process and a threshold time quanta. A method includes preempting a process running on an accelerated processing device based upon a running time of the process and a threshold time quanta. | 08-09-2012 |
20130135327 | Saving and Restoring Non-Shader State Using a Command Processor - Provided is a system including a command processor configured for interrupting processing of a first set of instructions executing within a shader core. | 05-30-2013 |
20130141447 | Method and Apparatus for Accommodating Multiple, Concurrent Work Inputs - A method of accommodating more than one compute input is provided. The method creates an APD arbitration policy that dynamically assigns compute instructions from a sequence of instructions awaiting processing to the APD compute units for execution of a run list. | 06-06-2013 |
20130147816 | Partitioning Resources of a Processor - Embodiments describe herein provide an apparatus, a computer readable medium and a method for simultaneously processing tasks within an APD. The method includes processing a first task within an APD. The method also includes reducing utilization of the APD by the first task to facilitate simultaneous processing of the second task, such that the utilization remains below a threshold. | 06-13-2013 |
20130155077 | Policies for Shader Resource Allocation in a Shader Core - A method of determining priority within an accelerated processing device is provided. The accelerated processing device includes compute pipeline queues that are processed in accordance with predetermined criteria. The queues are selected based on priority characteristics and the selected queue is processed until a time quantum lapses or a queue having a higher priority becomes available for processing. | 06-20-2013 |
