Operating a computer network uses a routing and control protocol, the computer network having an interconnect fabric including routing and control distribution devices and fabric interface devices, each of the routing and control distribution devices and each of the fabric interface devices having a state machine having an input processing unit having parallel input buffers, an output processing unit having parallel output buffers and an arbiter; operating the state machine based on a set of instructions and a table located at the state machine; transferring data from the input processing unit to the output processing unit; choosing a highest priority currently flit occupied parallel input buffer located in the input processing unit for data transmission on a highest priority currently flit occupied channel; and; interrupting the highest currently flit occupied priority channel when one of the parallel input buffers is detected to contain a superseding even higher priority flit.

A data distribution system includes a data distribution module and at least two host-bus adapters coupled to the data distribution module. The data distribution system includes a memory-management system including a plurality of memory regions. The memory-management system is coherent across the plurality of memory regions and an absolute address of each of the plurality of memory regions accessed by a same offset.

Switchless interconnect fabric message distribution includes end-to-end partitioning of message pathways or multiple priority levels with interrupt capability. A switchless interconnect fabric message distribution system includes a data distribution module and at least two host-bus adapters connected to the data distribution module. The data distribution module includes partition first in first out buffers. Each of the host-bus adapters includes an input manager connected to input priority first in first out buffers and an output manager connected to priority first in first out buffers.

Operating a data distribution including a data distribution module and a plurality of host-bus adapters coupled to the data distribution module can include defining a coherent group that includes a set of members that includes the plurality of host-bus adapters; providing a group-coherent memory area in each of the set of members; and initiating a one-to-all broadcast message from a one of the plurality of host-bus adapters to all of the set of members when the one of the plurality of host-bus adapters requests a write to its local group-coherent memory area. The group-coherent memory area in each of the set of members is physically mirrored with a temporal coherence and no semaphores or access enables are required to achieve the temporal coherence of the coherent group.

A parallel multicast star topology data network includes a plurality of input buffers, a first arbitration mechanism coupled to the plurality of input buffers, a plurality of output buffers coupled to the first arbitration mechanism and a plurality of interconnect exits coupled to the plurality of output buffers. When packet contents of a multicast message are ready for release from the first arbitration mechanism then all of the packet contents are substantially simultaneously released to the plurality of output buffers and then substantially simultaneously to the plurality of interconnect exits.

A multidimensional symbol encoder is coupled to a transmitter. Multidimensional symbols are encoded by concatenating two or more partial symbols, wherein individual intervals of up and down sections of the two or more partial symbols are independently controlled as to duration. A multidimensional symbol decoder is coupled to a receiver. Multidimensional symbols are decoded by measuring duration of individual intervals i) that are independently controlled as to duration and ii) that are up and down sections of two or more concatenated partial symbols.
