Abstract
An apparatus comprises an interconnect providing communication paths between agents coupled to the interconnect. A coordination agent is provided which performs an operation requiring sending a request to each of a plurality of target agents, and receiving a response from each of the target agents, the operation being unable to complete until the response has been received from each of the target agents. Storage circuitry is provided which is accessible to the coordination agent and configured to store, for each agent that the coordination agent may communicate with via the interconnect, a latency indication for communication between that agent and the coordination agent. The coordination agent is configured, prior to performing the operation, to determine a sending order in which to send the request to each of the target agents, the sending order being determined in dependence on the latency indication for each of the target agents.
