摘要
Methods, apparatus, and products are disclosed for providing point to point data communications among compute nodes in a global combining network of a parallel computer that include: determining a class route identifier available for all of the nodes along a communications path from an origin node to a target node; configuring network hardware of each node along the communications path with routing instructions in dependence upon the available class route identifier and the network's topology; transmitting, by the origin node along the communications path, a network packet to the target node, including encoding the available class route identifier in the network packet; and routing, by the network hardware of each node along the communications path, the network packet to the target node in dependence upon the routing instructions for each node and the available class route identifier.
