A method for providing notification of completion of a computing task includes providing access to an information handling resource for a first information handling system, registering the first information handling system with a first completion queue, submitting commands from the first information handling system to a first submission queue, providing access to the information handling resource for second first information handling system, registering the second information handling system with the first completion queue, and submitting commands from the second information handling system to a second submission queue. Upon execution of commands in the first submission queue and the second submission queue, an entry in is created a first completion queue. Upon the creation of an entry in the first completion queue, an interrupt is selectively sent to the first information handling resource and to the second information handling resource.
