| 主权项 | 1. A method, comprising: receiving a notification that an attempt to retrieve data from a memory for a requesting process running on an accelerated processing device failed; determining a type of memory exception that occurred based on the received notification; accessing collected updatable statistics associated with the determined type of memory exception; responsive to the notification, determining whether to preempt the process based upon the statistics; and initiating preempting the process from running on the accelerated processing device based upon the determining whether to preempt the process. | ||
