Design of algorithm-based fault-tolerant multiprocessor systems for concurrent error detection and fault diagnosis
Bapi Vinnakota, Niraj Kumar Jha · IEEE Transactions on Parallel and Distributed Systems · 1994
Algorithm-based fault tolerance (ABPT) is a low-overhead system-level concurrent error detection and fault location scheme for multiprocessor systems. We present new methods for the design of ABFT systems. Our design procedure is applicable to a wide range of systems in which processors share data elements. A feature of our design approach is that the type of checks to be used in the final system can be controlled by the system designer. We also present some new bounds on the number of checks needed in ABFT system design.>
