ABSTRACT:
Disclosed is a new torus switch with low latency performance improves torus network connection time by trying multipaths in one single high speed operation. This multipath approach can be directed at establishing a connection between two specific nodes over various alternate routes simultaneously. If only one route is available, the multipath approach will find that path instantaneously and establish the desired connection with minimal latency. If several links are available, the multipath method establishes the desired connection over only one of the available links and leaves the other options free to be used by other connections. In addition, routing at intermediate torus network stages improves over the wormhole approach.
