Patent attributes
Embodiments disclosed herein generally include a computer-implemented method, computer program product, and system to facilitate offloaded and parallelized direct memory access (DMA) translation table operations. The method includes a hypervisor requesting a lease on an auxiliary parallel processing element assigned to a first virtual machine hosted by the hypervisor. The method further includes receiving a grant of the lease, whereby ownership of the auxiliary parallel processing element is transferred from the first virtual machine to the hypervisor. The method further includes, during the lease, providing a predefined program to execute on the auxiliary parallel processing element in order to perform a desired operation on the hypervisor DMA translation table and with parallelism. The method further includes, upon completion of the predefined program, terminating the lease by the hypervisor, whereby ownership of the auxiliary parallel processing element is returned to the first virtual machine.
