摘要： A graphics processing system includes a plurality of processing units, wherein the graphics processing system is configured to process a task first and second times at the plurality of processing units. Data identifying which processing unit of the plurality of processing units the task has been allocated to is consulted on allocating the task to a processing unit for processing for a second time, and, in response, the task is allocated for processing for the second time to any processing unit of the plurality of processing units other than the processing unit to which the task was allocated for processing for a first time.

摘要： A redundant computer system utilizing comparison diagnostics and voting techniques includes a plurality of redundant channels. Each pair of the processors receives/obtains process information from I/O modules via dual redundant sensors (DRS). The processors execute an application program, whereby output module is utilized for comparing output data of the two processors. Output module receives output data from neighboring modules, if there is a deviation or other disparity in the output data. Each pair of processors, a voter and an improper sequence detector component disables the output module, if a majority of signals vote that output module fails. In addition, the system uses 2-of-3 voting, the system remains operational in the presence of up two transient or hard failures.

摘要： Computer-implemented methods and systems are provided for detecting a failed server. The computer-implemented method includes creating a proxy file for each server of a plurality of servers in an active state and assigning a timestamp to each proxy file of each server of the plurality of servers. The computer-implemented method further includes permitting each server to inspect each timestamp of each proxy file of each server of the plurality of servers and determining whether the timestamp assigned to each proxy file of each server of the plurality of servers exceeds a predetermined threshold. The computer-implemented method further includes, in response to a timestamp of a proxy file of a failed server exceeding the predetermined threshold, allowing another server of the plurality of servers to complete remaining work of the failed server.

摘要： A coupling device for connection of one of two servers at a time to a data transmission network as well as to a data transmission network having a coupling device. The device has a first and second terminal for connecting a first and second server and a third terminal for connection to the data transmission network. A switch device is provided having a first switching state where the third terminal is connected to the first terminal and disconnected from the second terminal, and a second switching state, where the third terminal is connected to the second terminal and disconnected from the first terminal. The switch device is adapted to assume a switching state, when it is provided with the energy signal by the power supply, and to assume another switching state, when it is not provided with the energy signal by the power supply.

摘要： A system, method and computer program product to execute a first and a second work-group, and compare the signature variables of the first work-group to the signature variables of the second work-group via a synchronization mechanism. The first and the second work-group are mapped to an identifier via software. This mapping ensures that the first and second work-groups execute exactly the same data for exactly the same code without changes to the underlying hardware. By executing the first and second work-groups independently, the underlying computation of the first and second work-groups can be verified. Moreover, system performance is not substantially affected because the execution results of the first and second work-groups are compared only at specified comparison points.

摘要： A high integrity touch screen system includes, but is not limited to, a display screen, a first sensor array to detect a touch on the display screen and to generate a first set of touch position coordinates, a first processor connected to the first sensor array and configured to receive the first set of touch position coordinates, a second sensor array to detect the touch on the display screen and to generate a second set of touch position coordinates and a second processor connected to the second sensor array and configured to receive the second set of touch position coordinates. The first processor and the second processor cooperate to compare the first set of touch position coordinates with the second set of touch position coordinates and to invalidate the touch when the first set of touch position coordinates and the second set of touch position coordinates do not substantially coincide.
