摘要： One embodiment of the present invention sets forth a technique for compositing a rendered path object into an image buffer. A shader program executing within a graphics processing unit (GPU) performs a stenciling operation for the path object and subsequently performs a texture barrier operation, which invalidates caches configured to store texture and frame buffer data within the GPU. The shader program then performs covering operation for the path object in which the shader renders color samples for the path object and composites the color samples into an image buffer. The shader program binds to the image buffer for access as both a texture map and a writeable image. Stencil values are reset when corresponding pixels are written once per path object, and texture caches are invalidated via the texture barrier operation, which is performed after each covering operation per path object.
摘要翻译：本发明的一个实施例提出了一种用于将渲染的路径对象合成到图像缓冲器中的技术。在图形处理单元（GPU）内执行的着色器程序执行路径对象的模板操作，并且随后执行纹理屏障操作，这使得被配置为在GPU内存储纹理和帧缓冲器数据的高速缓存无效。着色程序然后对路径对象执行覆盖操作，其中着色器为路径对象呈现颜色样本，并将颜色样本复合到图像缓冲区中。着色器程序绑定到图像缓冲区以作为纹理贴图和可写图像。当每个路径对象写入一次对应的像素时，模板值被复位，纹理高速缓存通过每个路径对象的每个覆盖操作之后执行的纹理屏障操作无效。

摘要： One embodiment of the present invention sets forth a technique for performing low latency computation on a parallel processing subsystem. A low latency functional node is exposed to an operating system. The low latency functional node and a generic functional node are configured to target the same underlying processor resource within the parallel processing subsystem. The operating system stores low latency tasks generated by a user application within a low latency command buffer associated with the low latency functional node. The parallel processing subsystem advantageously executes tasks from the low latency command buffer prior to completing execution of tasks in the generic command buffer, thereby reducing completion latency for the low latency tasks.

摘要： One embodiment of the present invention sets forth a set of application programming interface (API) extensions that enable a software application to control the processing work assigned to each GPU in a multi-GPU system. The software application enumerates a list of available GPUs, sets an affinity mask from the enumerated list of GPUs and generates an affinity device context associated with the affinity mask. The software application can then generate and utilize an affinity rendering context that directs rendering commands to a set of explicitly selected GPUs, thus allocating work among specifically selected GPUs. The software application is empowered to use domain specific knowledge to better optimize the work assigned to each GPU, thus achieving greater overall processing efficiency relative to the prior art techniques.

The method includes the steps of generating a state object that specifies a set of properties that is needed to execute a first graphics command within the graphics processor, storing in the state object a value associated with a first property included in the set of properties, marking a second property included in the set of properties as a dynamic property, where a value associated with the second property is not stored in the state object and can be updated without having to modify the state object, and transmitting the state object to the graphics processor in order to execute the first graphics command.

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.
