Methods and systems for communications between hardware components
Various examples are directed to an arrangement comprising a first hardware compute element and a hardware balancer element. The first hardware compute element may send a first request message to a hardware balancer element. The first request message may describe a processing task. The hardware balancer element may send a second request message towards a second hardware compute element for executing the processing task and send to the first compute element a first reply message in reply to the first request message. After sending the first reply message, the hardware balancer element may receive a first completion request message indicating that the processing task is assigned and send, to the first hardware computing element, a second completion request message, the second completion request message indicating that the processing task is assigned.
