Appl. No.:

13/292721

Inventors:

Benjamin Thomas SANDER - Austin TX, US
Michael Houston - Cupertino CA, US
Newton Cheung - San Jose CA, US
Keith Lowery - Bothell WA, US

Assignee:

Advanced Micro Devices, Inc. - Sunnyvale CA

International Classification:

G06F 13/24

US Classification:

710263, 710269

Abstract:

A system, method and article of manufacture for an accelerated processing device (APD) to request a central processing unit (CPU) to process a task, comprising enqueuing a plurality of tasks on a queue using the APD, generating a user-level interrupt and transmitting to the CPU the plurality of tasks in the queue using an interrupt handler associated with a CPU thread.

Benjamin Thomas SANDER - Austin TX, US
Michael Houston - Cupertino CA, US
Newton Cheung - San Jose CA, US
Keith Lowery - Bothell WA, US

International Classification:

G06F 9/46

US Classification:

718102

Abstract:

Methods, systems and computer-readable mediums for task scheduling on an accelerated processing device (APD) are provided. In an embodiment, a method comprises: enqueuing one or more tasks in a memory storage module based on the APD; using a software-based enqueuing module; and dequeuing the one or more tasks from the memory storage module using a hardware-based command processor, wherein the command processor forwards the one or more tasks to the shader cote.

Newton Cheung - San Jose CA, US
Keith Lowery - Bothell WA, US

International Classification:

G06F 9/54

US Classification:

719313

Abstract:

Provided herein is a method for optimizing communication for system calls.

International Classification:

G06F 9/52

US Classification:

718105

Abstract:

A method, system and article of manufacture for balancing a workload on heterogeneous processing devices. The method comprising accessing a memory storage of a processor of one type by a dequeuing entity associated with a processor of a different type, identifying a task from a plurality of tasks within the memory that can be processed by the processor of the different type, synchronizing a plurality of dequeuing entities capable of accessing the memory storage, and dequeuing the task form the memory storage

Abstract:

Systems, methods, and articles of manufacture for optimizing task scheduling on an accelerated processing device (APD) device are provided. In an embodiment, a method comprises: enqueuing, using the APD, one or more tasks in a memory storage; and dequeuing, using the APD, the one or more tasks from the memory storage using a hardware-based command processor, wherein the command processor forwards the one or more tasks to a shader core.

International Classification:

G06F 9/46

US Classification:

719318

Abstract:

A system, method, and computer program product are provided for improving resource utilization of multithreaded applications. Rather than requiring threads to block while waiting for data from a channel or requiring context switching to minimize blocking, the techniques disclosed herein provide an event-driven approach to launch kernels only when needed to perform operations on channel data, and then terminate in order to free resources. These operations are handled efficiently in hardware, but are flexible enough to be implemented in all manner of programming models.
