Messages (20) are routed through an array (10) of data processing nodes (N1-N16) which are intercoupled with channels in rows and columns. Under certain conditions (not state 30 and not state 31a of Fig. 4), a message can exit a node in either one of two directions; and this enables the message to reach its destination by multiple routes. Under other conditions (state 30 or state 31a of Fig. 4), the message must exit the node in only predetermined direction, and that direction is selected to avoid message routing deadlocks.
