Patent CA-2351040-A1 (CA)
Inventor: TANNHOF PASCAL
IPC: G06N3/063
Filed: 2001-06-19
Abstract: The method and circuits of the present invention aim to associate a norm to each component of an input pattern presented to an input space mapping algorithm based artificial neural network (ANN) during the distance evaluation process. The set of norms, referred to as the "component" norms is memorized in specific memorization means in the ANN.  In a first embodiment, the ANN is provided with a global memory, common for all the neurons of the ANN, that memorizes all the component norms. For each component of the input pattern, all the neurons perform the elementary (or partial) distance calculation with the corresponding prototype components stored therein during the distance evaluation process using the associated component norm. The distance elementary calculations are then combined using a "distance" norm to determine the final distance between the input pattern and the prototypes stored in the neurons. In another embodiment, the set of component norms is memorized in the neurons themselves in the prototype memorization means, so that the global memory is no longer physically necessary. This implementation allows to significantly optimize the consumed silicon area when the ANN is integrated in a silicon chip.

Abstract: A clustered computer system, apparatus, program product and method utilize a group member-initiated shutdown process to terminate clustering on a node in an automated and orderly fashion, typically in the event of a failure detected by a group member residing on that node. As a component of such a process, node leave operations are initiated on the other nodes in a clustered computer system, thereby permitting any dependency failovers to occur in an automated fashion. Moreover, other group members on a node to be shutdown are preemptively terminated prior to local detection of the failure within those other group members, so that termination of clustering on the node may be initiated to complete a shutdown operation.
