ABSTRACT:
A multi-dimensional node or processor arrangement allows a similar number of nodes in a linear array to be arranged in a more compact form, thus overcoming a latency problem in communications between the most distant nodes/processors. The multi-dimensional arrangement also allows for multiple paths between nodes. This feature greatly improves survivability of the system, such that when one node dies there is always at least one other path that is available to get to the other nodes in the system. Thus, the system can continue to run and only the resources of the one node that died are lost. A first set of routing rules governs the migration of communications between a source node and a destination node around the node array when all of the nodes are functioning. A secondary set of rules displaces or modifies the first set when a node is not functioning.
