Abstract: One embodiment of the present invention sets forth a technique for associating arbitrary parallel processing unit (PPU) contexts with a given central processing unit (CPU) thread. The technique introduces two operators used to manage the PPU contexts. The first operator is a PPU context push, which causes a PPU driver to store the current PPU context of a calling thread on a PPU context stack and to associate a named PPU context with the calling thread. The second operator is a PPU context pop, which causes the PPU driver to restore the PPU context of a calling function to the PPU context at the top of the PPU context stack. By performing a PPU context push at the beginning of a function and a PPU context pop prior to returning from the function, the function may execute within a single CPU thread, but operate on a two distinct PPU contexts.

Abstract: Each time a currently scheduled virtual machine (VM) accesses a hardware resource over a bus for the hardware resource via the currently scheduled VM running on a processor, a hardware component adjusts a bandwidth counter associated with usage of the bus for the hardware resource, without involvement of the currently scheduled VM or a hypervisor managing the currently scheduled VM. Responsive to the bandwidth counter reaching a threshold value, the hardware component issues an interrupt for handling by the hypervisor to maintain bandwidth quality-of-service (QoS) of bus bandwidth related to the hardware resource.

The hardware resource can be memory.

Abstract: A preempt of a live migratable workload, or job, in a distributed computing environment is performed, allowing it to release its resources for use by a higher priority workload by moving to another place in the distributed computing environment without interruption. A job scheduler receives a request to schedule a higher priority job, wherein resources needed to run the higher priority job are already dedicated for use by a currently running lower priority job.

A live migration of the lower priority job to another host is initiated, and its resources are then released. Upon a successful completion of the live migration of the lower priority job, the higher priority job is then dispatched to run using the now released resources.
