PROCESSING UNIT VIRTUALIZATION WITH SCALABLE OVER-PROVISIONING IN AN INFORMATION PROCESSING SYSTEM

Techniques are disclosed for processing unit virtualization with scalable over-provisioning in an information processing system. For example, the method accesses a data structure that maps a correspondence between a plurality of virtualized processing units and a plurality of abstracted processing units, wherein the plurality of abstracted processing units are configured to decouple an allocation decision from the plurality of virtualized processing units, and further wherein at least one of the virtualized processing units is mapped to multiple ones of the abstracted processing units. The method allocates one or more virtualized processing units to execute a given application by allocating one or more abstracted processing units identified from the data structure. The method also enables migration of one or more virtualized processing units across the system. Examples of processing units with which scalable over-provisioning functionality can be applied include, but are not limited to, accelerators such as GPUs.
