Abstract: During a debug mode of operation of a data processor it is determined whether a data access request is to a stack of the data processor. If not, a data trace message based on the data access request is generated for transmission to a debugger so long as an address being accessed by data access request meets a predefined address range criteria. Otherwise, if the data access request is to the stack of the data processor, a data trace message based on the data access request is prevented from being generated for transmission to the debugger regardless the predefined address range criteria.

Abstract: A computer hardware-implemented method, system, and/or computer program product prevents a cascading failure in a complex stream computer system causing an untrustworthy output from the complex stream computer system. Multiple upstream subcomponents in a complex stream computer system generate multiple outputs, which are used as inputs to a downstream subcomponent, wherein the multiple upstream subcomponents execute upstream computational processes. Each upstream computational process is examined to determine an accuracy of each identified output. An accuracy value is assigned to each of the multiple outputs from the upstream subcomponents, and weighting values are assigned to each of the inputs to the downstream subcomponent. The accuracy values and weighting values are utilized to dynamically adjust inputs to the downstream subcomponent until an output from the downstream subcomponent meets a predefined trustworthiness level.

Abstract: A computational geometry technique is utilized to detect, diagnose, and/or mitigate fault detection during the execution of a software application. Runtime measurements are collected and processed to generate a geometric enclosure that represents the normal, non-failing, operating space of the application being monitored. When collected runtime measurements are classified as being inside or on the perimeter of the geometric enclosure, the application is considered to be in a normal, non-failing, state. When collected runtime measurements are classified as being outside of the geometric enclosure, the application is considered to be in an anomalous, failing, state. In an example embodiment, the geometric enclosure is a convex hull generated in N-dimensional Euclidean space. Appropriate action (e.g., restart the software, turn off access to a network port) can be taken depending on where the measurement values lie in the space.

The new problem ticket is determined to specify the problem which has the root cause.

Abstract: A method is for handling an anomaly in an industrial control system (ICS) connected to a network with a plurality of other ICSs and an anomaly analyzer. An ICS receives status data from its own industrial process, and stores this status data as normal pattern data. The ICS transmits its own status data to one or more other ICSs. The ICS receives an indication from the anomaly analyzer that the ICS is suspected of having an anomaly. The ICS transmits alternate status data based on the normal pattern data stored during non-suspect operation, and stores the status data received from its own industrial process as real status data. In response to receiving from the anomaly analyzer an indication that the ICS is not operating anomalously, the ICS transmits the stored real data, and switches back to transmitting its own status data to one or more other ICSs.

Replacement cells can be used to shift or assign data when a self-identifying memory fault is present. A memory controller and memory module, alone or in combination may manage replacement cell use and facilitate driving a newly discovered faulty cell to a fault state if the faulty cell is not already at the fault state.
