Evaluating the Impact of SDC on the GMRES Iterative Solver

Elliott, J., Hoemmen, M., & Mueller, F. (2014, May 1).

By: J. Elliott n, M. Hoemmen* & F. Mueller n

topics (OpenAlex): Low-power high-performance VLSI design; Radiation Effects in Electronics; Parallel Computing and Optimization Techniques
TL;DR: This work derives inexpensive checks to detect the effects of an SDC in GMRES that work for a more general SDC model than presuming a bit flip, and shows that when GMRES is used as the inner solver of an inner-outer iteration, it can "run through" SDC of almost any magnitude in the computationally intensive orthogonalization phase.

Combining Partial Redundancy and Checkpointing for HPC

Elliott, J., Kharbas, K., Fiala, D., Mueller, F., Ferreira, K., & Engelmann, C. (2012, June 1).

By: J. Elliott n, K. Kharbas n, D. Fiala n, F. Mueller n, K. Ferreira * & C. Engelmann *

topics (OpenAlex): Distributed systems and fault tolerance; Parallel Computing and Optimization Techniques; Advanced Data Storage Technologies
TL;DR: This work contributes a model and analyzes the benefit of C/R in coordination with redundancy at different degrees to minimize the total wallclock time and resources utilization of HPC applications and conducts experiments with an implementation of redundancy within the MPI layer on a cluster.
