Software fault tolerance

WebMar 23, 2005 · SWIFT: software implemented fault tolerance. Abstract: To improve performance and reduce power, processor designers employ advances that shrink feature sizes, lower voltage levels, reduce noise margins, and increase clock rates. However, these advances make processors more susceptible to transient faults that can affect correctness. WebFault Tolerance simply means a system’s ability to continue operating uninterrupted despite the failure of one or more of its components. This is true whether it is a computer system, a cloud cluster, a network, or …
