A method of computational storage device intercommunication includes receiving a notification from a first storage controller of a first computational storage device indicating a presence of a message, in response to receiving the notification, transmitting a send message request to the first storage controller of the first computational storage device, and receiving the message from the first storage controller, storing the message to a host memory and notifying a host pseudo network device driver of availability of the message, determining whether a destination address of the message corresponds to a host user process that is local to the host or to a second user process that is local to a second embedded computer of a second computational storage device, and providing the message to the host user process or to the second embedded computer associated with the destination address.
