摘要： Embodiments described herein provide a method including receiving a command to schedule a first process and selecting a command queue associated with the first process. The method also includes scheduling the first process to run on an accelerated processing device and preempting a second process running on the accelerated processing device to allow the first process to run on the accelerated processing device.
摘要翻译： 本文描述的实施例提供了一种方法，包括接收调度第一进程的命令并选择与第一进程相关联的命令队列。 该方法还包括调度第一进程以在加速处理设备上运行并抢占在加速处理设备上运行的第二进程以允许第一进程在加速处理设备上运行。

摘要： A method resumes an accelerated processing device (APD) wavefront in which a subset of elements have faulted. A restore command for a job including a wavefront is received. A list of context states for the wavefront is read from a memory associated with a APD. An empty shell wavefront is created for restoring the list of context states. A portion of not acknowledged data is masked over a portion of acknowledged data within the restored wavefronts.

摘要： A method, apparatus and computer readable media for servicing page fault exceptions in a accelerated processing device (APD). A page fault related to a wavefront is detected. A fault handling request to a translation mechanism is sent when the page fault is detected. A fault handling response corresponding to the detected page fault from the translation mechanism is received. Confirmation that the detected page fault has been handled through performing page mapping based on the fault handling response is received.

摘要： Embodiments of the present invention provide a method of preempting a task. The method includes removing the task from the parallel processors via a scheduling mechanism. Responsive to the removing, the method also includes ceasing (i) retrieval of commands from a buffer associated with the task, (ii) dispatch of groups of work-items associated with the task, (iii) dispatch of wavefronts associated with the task, and (iiii) execution of the wavefronts. State information related to the task is saved.
