<p>The design of fault-tolerant hypercube multiprocessor architecture is discussed. The authors propose the detection and location of faulty processors concurrently with the actual execution of parallel applications on the hypercube using a novel scheme of algorithm-based error detection. System-level error detection mechanisms have been implemented for three parallel applications on a 16-processor Intel iPSC hypercube multiprocessor: matrix multiplication, Gaussian elimination, and fast Fourier transform. Schemes for other applications are under development. Extensive studies have been done of error coverage of the system-level error detection schemes in the presence of finite-precision arithmetic, which affects the system-level encodings. Two reconfiguration schemes are proposed that allow the authors to isolate and replace faulty processors with spare processors.</p>
