摘要： One embodiment of the present invention sets forth a method for accessing texture objects stored within a texture memory. The method comprises the steps of receiving a texture bind request from an application program, wherein the texture bind request includes an object identifier that identifies a first texture object stored in the texture memory and an image identifier that identifies a first image unit, binding the first texture object to the first image unit based on the texture bind request, receiving, within a shader engine, a first shading program command from the application program for performing a first memory access operation on the first texture object, wherein the memory access operation is a store operation or atomic operation to an arbitrary location in the image, and performing, within the shader engine, the first memory access operation on the first texture object via the first image unit.

摘要： A system and method for using command buffers as timeslices or periods of execution for a long running compute task on a graphics processor. Embodiments of the present invention allow execution of long running compute applications with operating systems that manage and schedule graphics processing unit (GPU) resources and that may have a predetermined execution time limit for each command buffer. The method includes receiving a request from an application and determining a plurality of command buffers required to execute the request. Each of the plurality of command buffers may correspond to some portion of execution time or timeslice. The method further includes sending the plurality of command buffers to an operating system operable for scheduling the plurality of command buffers for execution on a graphics processor. The command buffers from a different request are time multiplexed within the execution of the plurality of command buffers on the graphics processor.
