Abstract:
1. A method of transmitting a message from a sending node to a receiving node of a parallel computing system, comprising: encapsulating the message within a set of one or more data packets; transmitting a request to send (RTS) message from the sending node to the receiving node; prior to receiving a clear to send (CTS) message at the sending node, transmitting one or more of the data packets to the receiving node, wherein the one or more data packets transmitted prior to receiving the CTS message at the sending node are one of deterministically routed packets and fully described, dynamically routed packets; and upon receiving the CTS message at the sending node, transmitting any remaining packets of the set of one or more packets to the receiving node, wherein the one or more data packets transmitted after receiving the CTS message at the sending node are routed dynamically, such that the one or more packets arrive in a different sequence order at the receiving node from a sequence order in which the one or more packets are transmitted, whereby the message is transmitted from the sending node to the receiving node.
