A computer system and computer program captures diagnostic trace information in a computer system having a plurality of software images. Information is received that is associated with a first failure in a first one of the plurality of software images. The received information is distributed to others of the plurality of software images. Further information is captured that is associated with a second failure in another one of the plurality of software images. The information associated with a first failure in a first one of said plurality of software images is combined with the information associated with a second failure in another of said plurality of software images, and the combined information is analyzed in order to determine a cause of the first failure.

A method is provided for detecting a race condition of a parallel task when accessing a shared resource in a multi-core processing system. The method requires that a core requires only a read access to the data set of another core, thereby ensuring better decoupling of the tasks. In an initialisation phase, initial values of global variables are assigned, in an activation phase, each core determines if the other core has written new values to the variables and if so, detects a race condition. Initial values are restored for each variable in a deactivation phase.

A user-mode crash reporting system for generating a crash report when an application crashes is provided. The user-mode crash reporting system installs a crash handler to execute in the same process as the application when the application crashes. When the application crashes, the crash handler identifies a victim thread of the process that was executing at the time of a crash. The crash handler then walks a call stack of the victim thread to identify return addresses for returning from called functions of the application. The crash handler identifies offsets within the module corresponding to the return addresses and creates a call chain of functions using the identified offsets. The crash handler then generates a crash report based on the identified call chain.

A massively parallel real-time computing system receives input data events across many compute nodes, each with a processing algorithm in its processing pipeline. An Event Manager is placed before the algorithm processing pipelines, receives metadata about each incoming event, and collects and organizes it in a database. A fast histogram compares the metadata about each event to that of all the other events, in a processing interval. For sufficiently matching metadata, the events are forwarded to the processing nodes as “regular” events for processing. If the metadata for a processing interval does not match sufficiently, the histogram decides which events are the “correct” events and which events are “incorrect.” The “correct” events are sent on for processing and the “incorrect” events are combined with the “correct” metadata and sent back to the processing nodes to supplement or modify their incoming data to match the other nodes' expectations.

An encoder includes: a reading device that reads respective electric signals from two incremental patterns respectively having graduation array pitches different from each other; a control device that calculates a measurement value, based on the electric signals; and an output device that outputs the measurement value. The control device includes: an absolute position synthesis unit that synthesizes two electric signals to generate a synthesized absolute position; a detection unit that detects two relative positions from the two electric signals; a position calculation unit that performs an arithmetic operation between the relative positions and the synthesized absolute position to calculate a calculated absolute position; an absolute position comparison unit that compares the calculated absolute position with the synthesized absolute position; and a relative position comparison unit that compares the two relative positions with each other. The output device outputs error information, based on a comparison result output from the control device.

In a method of molecular scaffold hopping an interface of a scheduler computer sends instructions, prepared by the scheduler computer, to a job runner computer to perform a plurality of separate computational tasks. Each of the separate computational tasks includes calculating one or more chemical properties for a query molecule or molecules in a library of molecules. One or more of the plurality of separate computational tasks performed on the job runner computer are preemptible computing instances. Status indicators sent from the job runner computer are received by the interface for each of the plurality of separate computational tasks. The indicators are one of: incomplete, completed, or failed computing instances. The interface resends the instructions to the job runner computer that correspond to the separate computational tasks having the failed computing instance indicator to increase fault-tolerance against the separate computational tasks not attaining the completed computing instance indicator.
