摘要： A time slice group (TSG) is a grouping of different streams of work (referred to herein as “channels”) that share the same context information. The set of channels belonging to a TSG are processed in a pre-determined order. However, when a channel stalls while processing, the next channel with independent work can be switched to fully load the parallel processing unit. Importantly, because each channel in the TSG shares the same context information, a context switch operation is not needed when the processing of a particular channel in the TSG stops and the processing of a next channel in the TSG begins. Therefore, multiple independent streams of work are allowed to run concurrently within a single context increasing utilization of parallel processing units.
摘要翻译：时间片组（TSG）是共享相同上下文信息的不同工作流（本文称为“信道”）的分组。属于TSG的信道集合以预定的顺序被处理。然而，当通道在处理过程中停顿时，可以切换具有独立工作的下一个通道来完全加载并行处理单元。重要的是，由于TSG中的每个信道共享相同的上下文信息，当TSG中的特定信道的处理停止并且TSG中的下一个信道的处理开始时，不需要上下文切换操作。因此，允许多个独立的工作流在单个上下文中同时运行，增加并行处理单元的利用率。

摘要： One embodiment of the present invention sets forth a technique for receiving versions of state objects at one or more stages in a processing pipeline. The method includes receiving a first version of a state object at a first stage in the processing pipeline, determining that the first version of the state object is relevant to the first stage, incrementing a first reference counter associated with the first version of the state object, assigning the first version of the state object to work requests that arrive at the first stage subsequent to the receipt of the first version of the state object, and transmitting the first version of the state object to a second stage in the processing pipeline.

摘要： A technique for controlling the distribution of compute task processing in a multi-threaded system encodes each processing task as task metadata (TMD) stored in memory. The TMD includes work distribution parameters specifying how the processing task should be distributed for processing. Scheduling circuitry selects a task for execution when entries of a work queue for the task have been written. The work distribution parameters may define a number of work queue entries needed before a cooperative thread array” (“CTA”) may be launched to process the work queue entries according to the compute task. The work distribution parameters may define a number of CTAs that are launched to process the same work queue entries. Finally, the work distribution parameters may define a step size that is used to update pointers to the work queue entries.

摘要： One embodiment of the present invention sets forth a technique for encapsulating compute task state that enables out-of-order scheduling and execution of the compute tasks. The scheduling circuitry organizes the compute tasks into groups based on priority levels. The compute tasks may then be selected for execution using different scheduling schemes. Each group is maintained as a linked list of pointers to compute tasks that are encoded as task metadata (TMD) stored in memory. A TMD encapsulates the state and parameters needed to initialize, schedule, and execute a compute task.

摘要： One embodiment of the present invention sets forth a technique for enabling the insertion of generated tasks into a scheduling pipeline of a multiple processor system allows a compute task that is being executed to dynamically generate a dynamic task and notify a scheduling unit of the multiple processor system without intervention by a CPU. A reflected notification signal is generated in response to a write request when data for the dynamic task is written to a queue. Additional reflected notification signals are generated for other events that occur during execution of a compute task, e.g., to invalidate cache entries storing data for the compute task and to enable scheduling of another compute task.
