Apparatuses, methods and storage media associated with multiple multi-drop buses in a switch are provided herein. In some embodiments, the switch may include a multi-drop row bus to transmit a plurality of frames in a row dimension of the matrix switch and a multi-drop column bus to transmit the plurality of frames in a column dimension of the matrix switch. The switch may further include an input port to receive the plurality of frames and an output port to output the plurality of frames from the matrix switch. Other embodiments may be described and/or claimed.

Apparatus and method for using multiple multi-drop buses

A system and method for routing in a high-radix network. A packet is received and examined to determine if the packet can be routed adaptively. If the packet can be routed adaptively, the packet is routed adaptively, wherein routing adaptively includes selecting a column, computing a column mask, routing the packet to the column; and selecting an output port as a function of the column mask. If the packet can be routed deterministically, routing deterministically, wherein routing deterministically includes accessing a routing table to obtain an output port and routing the packet to the output port from the routing table.

Flexible routing tables for a high-radix router

A system and method for routing packets from one node to another node in a system having a plurality of nodes connected by a network. A node router is provided in each node, wherein the node router includes a plurality of network ports, including a first and a second network port, wherein each network port includes a communications channel for communicating with one of the other network nodes, a plurality of virtual channel input buffers and a plurality of virtual channel staging buffers, wherein each of the virtual channel staging buffers receives data from one of the plurality of input buffers.

Reduced arbitration routing system and method

A system and method for speculative forwarding of packets received by a router, wherein each packet includes phits and wherein one or more phits include a cyclic redundancy code (CRC). A packet is received and phits of the packet are forwarded to router logic. A cyclic redundancy code for the packet is calculated and compared to the packet's cyclic redundancy code. An error is generated if the cyclic redundancy codes don't match. If the cyclic redundancy codes don't match, a phit of the packet is modified to reflect the error, the CRC is corrected and the corrected CRC is forwarded to the router logic along with the phit reflecting the CRC error. At the router logic, a check is made to see if the packet is still within the router logic. If the packet is still within the router logic and there was a CRC error, the packet is discarded. If, however, the packet is no longer within the router logic and there was a CRC error, the packet is modified so that the next router discards the packet.
