Abstract: Embodiments described herein provide a method for identifying failure patterns in electronic devices. The method begins when a limit is determined for a parameter of interest. A series of the electronic devices is then tested using the limit of the parameter of interest. Failing devices are then identified and x and y coordinate values are plotted. Pattern recognition may be used to determine if the failures shown on the coordinate plot fit a failure pattern. The limit of the parameter of interest is then regressed in steps to the mean value of the failing devices and the electronic devices are retested. The failure pattern of the retested devices is examined to determine if the failure pattern fits a failure pattern. If the failure pattern fits a failure pattern then the parameter of interest may be found to affect the yield rate of production for the electronic devices.

Abstract: A message system for delivering data in the form messages between message clients comprises a server cluster with a group of client manager nodes and a group of independent message manager nodes. The client manager nodes have the function of managing client connections, whereas the message manager are configured to store and distribute messages. The system further comprising communication channel means in the form of a multicast messagebus for providing a multicast communication channel between said at least one client manager node and said at least one message manager node. The system guarantees delivery of a message by storing it until a receiver is ready to consume it.

Abstract: A means for guaranteeing the proper behavior as specified by the JMS semantics of clustered message server when the individual computer that comprise the cluster are separated by a network partition. A clustered message server is responsible for the reliable transportation of messages between different distributed computer applications. It employs multiple computers to perform a function that otherwise appears to be performed by a monolithic server running on one computer, but with more capacity and reliability than can be provided by one computer. If a computer in the cluster fails, another computer should automatically assume the role of the failed computer. However, it is not possible for the other machines in the cluster to detect the difference between the failure of one or more computers in the cluster, and the failure of data network connecting those computers.
