Abstract
In a massively parallel processing (MPP) system, bandwidth efficiency and message packet latency rates are improved by providing routing elements that detect, isolate and identify various routing errors. More specifically, system lock-up, caused by corrupted message packets, can be prevented by analyzing a given sequence of message packet codes and words as they are received by an input buffer associated with a routing element. By analyzing the sequence, it is possible to determine whether a tail code fails to arrive in the prescribed sequence. If a tail code has been received in a way that is inconsistent with an expected sequence, all of the message packet codes and words received at the buffer can be discarded until a valid message packet start code is received.
