摘要： One embodiment of the present invention sets forth a technique for managing the allocation and release of resources during multi-threaded program execution. Programmable reference counters are initialized to values that limit the amount of resources for allocation to tasks that share the same reference counter. Resource parameters are specified for each task to define the amount of resources allocated for consumption by each array of execution threads that is launched to execute the task. The resource parameters also specify the behavior of the array for acquiring and releasing resources. Finally, during execution of each thread in the array, an exit instruction may be configured to override the release of the resources that were allocated to the array. The resources may then be retained for use by a child task that is generated during execution of a thread.

摘要： One embodiment of the present invention sets forth a technique for automatic launching of a dependent task when execution of a first task completes. Automatically launching the dependent task reduces the latency incurred during the transition from the first task to the dependent task. Information associated with the dependent task is encoded as part of the metadata for the first task. When execution of the first task completes a task scheduling unit is notified and the dependent task is launched without requiring any release or acquisition of a semaphore. The information associated with the dependent task includes an enable flag and a pointer to the dependent task. Once the dependent task is launched, the first task is marked as complete so that memory storing the metadata for the first task may be reused to store metadata for a new task.
