Abstract: A parallel processor is configured to enforce job limits for virtual functions to facilitate an expected quality of service for each of the virtual functions assigned to a virtual machine executing at the processing unit. A scheduler schedules well-behaving virtual functions prior to badly-behaving virtual functions to prevent badly-behaving virtual functions from consuming a disproportionate share of hardware resources, thereby mitigating an impact of the badly-behaving virtual functions on the quality of service of the well-behaving virtual functions.

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.
