Abstract: A technique for operating an auxiliary processing device is provided. The technique includes based on a first request specifying a handle received from a client, requesting work be performed via a first auxiliary processing device mapped to the handle; responsive to restoration from hibernation, updating a mapping for the handle to refer to a second auxiliary processing device; and based on a second request specifying the handle received from the client, requesting work be performed via the second auxiliary processing device.

Abstract: Systems and methods are provided related to a scheduler to receive a job request from a virtual function associated with a tenant for execution by at least one processing unit. The scheduler validates the job request in accordance with one or more defined restrictions associated with the tenant and, responsive to successful validation, provides the job request for execution by the processing unit via one or more physical functions associated with the processing unit. In certain embodiments, multi-level enforcement of the defined restrictions are provided via user-mode and kernel-mode drivers associated with the virtual function that are also enabled to validate job requests based on the defined restrictions.
