Methods and apparatus perform fault isolation in multiple node computing systems using commutative error detection values for—example, checksums—to identify and to isolate faulty nodes. When information associated with a reproducible portion of a computer program is injected into a network by a node, a commutative error detection value is calculated. At intervals, node fault detection apparatus associated with the multiple node computer system retrieve commutative error detection values associated with the node and stores them in memory. When the computer program is executed again by the multiple node computer system, new commutative error detection values are created and stored in memory. The node fault detection apparatus identifies faulty nodes by comparing commutative error detection values associated with reproducible portions of the application program generated by a particular node from different runs of the application program. Differences in values indicate a possible faulty node.

An apparatus and method for capturing data packets for analysis on a network computing system includes a sending node and a receiving node connected by a bi-directional communication link. The sending node sends a data transmission to the receiving node on the bi-directional communication link, and the receiving node receives the data transmission and verifies the data transmission to determine valid data and invalid data and verify retransmissions of invalid data as corresponding valid data. A memory device communicates with the receiving node for storing the invalid data and the corresponding valid data. A computing node communicates with the memory device and receives and performs an analysis of the invalid data and the corresponding valid data received from the memory device.
摘要:
A method and apparatus for re-utilizing partially failed compute resources in a massively parallel super computer system. In the preferred embodiments the compute node comprises a number of clock domains that can be enabled separately. When an error in a compute node is detected, and the failure is not in network communication blocks, a clock enable circuit enables the clocks to the network communication blocks only to allow the partially failed compute node to be re-utilized as a network resource. The computer system can then continue to operate with only slightly diminished performance and thereby improve performance and perceived overall reliability.
