    • One embodiment of the present invention sets forth a technique for executing an operation once work associated with a version of a state object has been completed. The method includes receiving the version of the state object at a first stage in a processing pipeline, where the version of the state object is associated with a reference count object, determining that the version of the state object is relevant to the first stage, incrementing a counter included in the reference count object, transmitting the version of the state object to a second stage in the processing pipeline, processing work associated with the version of the state object, decrementing the counter, determining that the counter is equal to zero, and in response, executing an operation specified by the reference count object.
    • 本发明的一个实施例提出了一旦与状态对象的版本相关联的一次工作已经完成的执行操作的技术。 该方法包括在处理流水线中的第一阶段接收状态对象的版本,其中状态对象的版本与引用计数对象相关联,确定状态对象的版本与第一阶段相关,递增 包括在引用计数对象中的计数器,将状态对象的版本发送到处理流水线中的第二阶段,处理与状态对象的版本相关联的工作,递减计数器,确定计数器等于零,以及 作为响应,执行由引用计数对象指定的操作。

    • 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.
    • 用于控制多线程系统中的计算任务处理的分布的技术将每个处理任务编码为存储在存储器中的任务元数据(TMD)。 TMD包括指定如何分配处理任务以进行处理的工作分配参数。 调度电路在写入任务的工作队列的条目时选择执行任务。 工作分配参数可以定义在协作线程数组“(”CTA“)可以根据计算任务发起处理工作队列条目之前所需的工作队列条目数,工作分配参数可以定义多个CTAS, 被启动以处理相同的工作队列条目。最后,工作分配参数可以定义用于更新指向工作队列条目的指针的步长。
