Abstract
Official abstract text for this publication.
A system, method and computer program product to execute a first and a second work-item, and compare the signature variable of the first work-item to the signature variable of the second work-item. The first and the second work-items are mapped to an identifier via software. This mapping ensures that the first and second work-items execute exactly the same data for exactly the same code without changes to the underlying hardware. By executing the first and second work-items independently, the underlying computation of the first and second work-item can be verified. Moreover, system performance is not substantially affected because the execution results of the first and second work-items are compared only at specified comparison points.
First claim
Opening claim text (preview).
What is claimed is: 1. A system comprising: a processor including a plurality of compute units, each compute unit including a plurality of processing elements that is associated with that respective compute unit, each of the plurality of processing elements including a respective private memory that is associated exclusively with that processing element, configured to perform operations comprising: executing a first work-item on a first processing element and a second work-item…
