Abstract: Methods, articles, and systems for determining a probable cause of a component's abnormal behavior are described. To determine the probable cause, a computing device computes, for one or more pairs of components having dependency relationships, a likelihood that behavior of one component of a pair is impacting behavior of the other component of the pair. This computing is based on joint historical behavior of the pair of components. The computing device then determines that one of a plurality of components is a probable cause of the abnormal behavior based on the computed likelihoods.

Abstract: A technique determines which configuration change(s) caused an application invocation failure of a computer application without the need for a knowledge database. To determine which configuration change is the most likely cause, the cause analysis program (121) checks other computers (102) that have experienced the same configuration changes. The cause analysis program checks and counts the application invocation results before and after each configuration change is done. If the same configuration changes are found in the other computers, the program checks whether each configuration change caused or cured the same problem in that computer. The program counts the similar cases for all of the computers. Subsequently, the program calculates the ratio of those instances involving a change from success to failure and the ratio of those instances involving a change from failure to success out of all instances for each configuration change.

Abstract: A software optimization system isolates an effect of a change in a control variable from effects of ongoing, unknown changes in other variables. The system discards effects due to noise so that effects of interest to a programmer are more easily visible. The software optimization system treats variations in one or more control variables and in the output of the system as signals. The system varies the control variable at a specific frequency unlikely to correlate with uncontrolled variations in external variables. The system uses digital signal processing (DSP) techniques to filter the output, isolating the frequency of the control variable variation. The system then compares the resulting filtered output to the input to determine the approximate effect of the variation in the control variable.

When an error is detected, machine context and other relevant information is formatted for entry to a barcode generator unit. The a barcode generator unit received formatted text or codes, and outputs a 2-D barcode for visible capture. The barcode image is ultimately transformed into an electronic image which may be sent to an error reporting site, or individual. The error reporting site uses a decoding unit to decode the high contrast graphical image of the 2-D barcode. The resulting decoded information provides an analyst, or automated system with information relevant to debugging the error. Other embodiments are described and claimed.

Abstract: Failure analysis method and apparatus using failure rate data in coordination with the power on hours to more efficiently resolve computer system failures without occupying system memory or processor bandwidth. In response to a system failure, a baseboard management controller (BMC) notes the time of failure and the elapsed operating time of system components. In response to a failure of the computer system, the BMC accesses industry standard failure rate data correlating the elapsed operating time with the probability of failure for each component. By cross-referencing the time of failure with the failure rate data, the BMC automatically determines the probability of failure of each component at the time of failure of the computer system. The BMC generates a component replacement list identifying the component that currently has the highest probability of failure.

Abstract: A diagnostic server and a controlling method are provided. In the method, the diagnostic server receives a packet including at least one frame and performs error checking on each frame included in the packet. The diagnostic server receives a retransmitted packet upon determining from the result of error checking that a frame in the packet has an error. The diagnostic server performs error checking on each frame included in the retransmitted packet and restores the frame included in the packet based on the retransmitted packet when a frame, which is located in a location corresponding to the error frame, included in the retransmitted packet has no error. In the case where a packet including product information is transmitted, this method can reduce the number of retransmissions of the same packet required to acquire an error-free packet.

Abstract: The execution environment provides for scalability where components will execute in parallel and exploit various patterns of parallelism. Dataflow applications are represented by reusable dataflow graphs called map components, while the executable version is called a prepared map. Using runtime properties the prepared map is executed in parallel with a thread allocated to each map process.

Port implementation supports multi-state null value tokens to more accurately report exceptions. Data tokens are batched to minimize synchronization and transportation overhead and thread contention.

It has been found that various ways of decoupling are possible, using any suitable transport scheme including physical and electronic, both wired and wireless.
