摘要： One embodiment of the present invention sets forth a technique for error-checking a compute task. The technique involves receiving a pointer to a compute task, storing the pointer in a scheduling queue, determining that the compute task should be executed, retrieving the pointer from the scheduling queue, determining via an error-check procedure that the compute task is eligible for execution, and executing the compute task.

摘要： Systems and methods for auto-throttling encapsulated compute tasks. A device driver may configure a parallel processor to execute compute tasks in a number of discrete throttled modes. The device driver may also allocate memory to a plurality of different processing units in a non-throttled mode. The device driver may also allocate memory to a subset of the plurality of processing units in each of the throttling modes. Data structures defined for each task include a flag that instructs the processing unit whether the task may be executed in the non-throttled mode or in the throttled mode. A work distribution unit monitors each of the tasks scheduled to run on the plurality of processing units and determines whether the processor should be configured to run in the throttled mode or in the non-throttled mode.

摘要： One embodiment of the present invention sets forth a technique for storing only the enabled components for each enabled vector and writing only enabled components to one or more specified render targets. A shader program header (SPH) file provides per-component mask bits for each render target. Each enabled mask bit indicates that the pixel shader generates the corresponding component as an output to the raster operations unit. In the hardware, the per-component mask bits are combined with the applications programming interface (API)-level per-component write masks to determine the components that are updated by the shader program. The combined mask is used as the write enable bits for components in one or more render targets. One advantage of the combined mask is that the components that are not updated are not forwarded from the pixel shader to the ROP, thereby saving bandwidth between those processing units.
摘要翻译： 本发明的一个实施例提出了一种用于仅存储每个启用向量的启用组件并仅将启用的组件写入一个或多个指定的渲染目标的技术。 着色器程序头（SPH）文件为每个渲染目标提供每个组件掩码位。 每个启用的屏蔽位指示像素着色器生成相应的组件作为光栅操作单元的输出。 在硬件中，每个组件掩码位与应用程序编程接口（API）级的每个组件写入掩码相结合，以确定由着色器程序更新的组件。 组合掩码用作一个或多个渲染目标中的组件的写使能位。 组合掩码的一个优点是未更新的组件不会从像素着色器转发到ROP，从而节省了这些处理单元之间的带宽。

摘要： One embodiment of the present invention sets forth a technique for configuring a graphics processing pipeline (GPP) to process data according to one or more shader programs. The method includes receiving a plurality of pointers, where each pointer references a different shader program header (SPH) included in a plurality of SPHs, and each SPH is associated with a different shader program that executes within the GPP. For each SPH included in the plurality of SPHs, one or more GPP configuration parameters included in the SPH are identified, and the GPP is adjusted based on the one or more GPP configuration parameters.

摘要： A method for providing state inheritance across command lists in a multi-threaded processing environment. The method includes receiving an application program that includes a plurality of parallel threads; generating a command list for each thread of the plurality of parallel threads; causing a first command list associated with a first thread of the plurality of parallel threads to be executed by a processing unit; and causing a second command list associated with a second thread of the plurality of parallel threads to be executed by the processing unit, where the second command list inherits from the first command list state associated with the processing unit.
