Abstract

A distributed switchless system characterized by full mesh connectivity is disclosed. The full mesh distributed switchless system allows direct and indirect communication between a source node and a destination node. In direct communication, data propagates via links connecting the source and destination nodes. In indirect communication, data is first sent to an intermediate node via links connecting the source and intermediate nodes. The intermediate node sends the data to the destination node via links connecting the intermediate node and the destination node. The traffic can be divided into all available links across the nodes, rather than only the links connecting the source and destination nodes. Because indirect communication uses more links compared to direct communication, the traffic in each link is smaller. Consequently, the switchless distributed interconnect system can operate with fewer links between any two nodes and links with smaller bandwidth.

Dependent claims

A method of processing data in a full mesh distributed switchless interconnect system comprising:

receiving by a first processing engine in a full mesh distributed switchless interconnect system including a plurality of processing engines wherein each of the processing engines in the interconnect system includes a direct switchless connection to each other processing engine, first data indicating a first destination processing engine;
determining by the first processing engine that the first processing engine is the first destination processing engine in the full mesh distributed switchless interconnect system and processing the first data by the first processing engine based on determining that the first processing engine is the first destination processing engine;
receiving, by the first processing engine, second data indicating a second destination processing engine;
determining by the first processing engine that the first processing engine is not the second destination processing engine;
evaluating an availability of the direct switchless connection between the first processing engine and the second destination processing engine in the full mesh distributed switchless interconnect system;
and
transmitting the second data to an intermediate processing engine based on a result of the evaluation of the availability of the direct switchless connection indicating the direct switchless connection is not available.
