Abstract

See full text

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, during the transmission of a message packet from a first routing element to a second routing element in the MPP system, link lock-up can be prevented effectively by determining whether the message packet contains a certain predefined quantity of data. Control codes, used for establishing the end to the message packet, can then be inserted into the message packet if it is determined that the message packet does, in fact, contain the predefined quantity of data.
