ABSTRACT
<p><b>Abstract</b>—The use of backward error assertions combined with iterative refinement has been suggested for the correction of small fault induced errors in the floating point solution of linear systems. We extend this to the correction of large errors, typically caused by the failure of a single processor (or column of processors) in an array.</p>
INDEX TERMS
Fault tolerance, algorithm-based fault tolerance, backward error assertions, floating point computation.
