1. An asynchronous system of multiprocessor computers ("nodes") connected in a hypercube network configured as a cube, which cube includes nodes at each corner of the cube, bidirectional communication lines for passing data messages along the edge of the cube, and any node in said network being designable as a local node which has its nearest nodes in said network designated as immediate neighboring nodes, said system comprising:

  • a dedicated I/O processor at every node assigned only for communication tasks throughout said cube-configured network, with each I/O processor operating independently of every other I/O processor in the network to control its own node'"'"'s data message passing to its own immediate neighboring nodes;

    a local FIFO at each node connected to a bidirectional communication link which is connected between a local node and each immediate neighboring node;

    A FIFO-loading control line leading from a local node to each immediate neighboring node in said cube-configured network; and

    means associated with a local node'"'"'s I/O processor and under control of said local I/O processor for loading the neighboring node'"'"'s FIFO via signaling over said bidirectional communication lines and said control line.
