Exploiting Data Representation for Fault Tolerance
James Elliott, Mark Hoemmen, Frank Mueller
We explore the link between data representation and soft errors in dot products. We present an analytic model for the absolute error introduced should a soft error corrupt a bit in…
Fault-tolerant linear solvers via selective reliability
Patrick G. Bridges, Kurt B. Ferreira, Michael A. Heroux +1
Energy increasingly constrains modern computer hardware, yet protecting computations and data against errors costs energy. This holds at all scales, but especially for the largest…
Implementing Communication-Optimal Parallel and Sequential QR Factorizations
James Demmel, Laura Grigori, Mark Hoemmen +1
We present parallel and sequential dense QR factorization algorithms for tall and skinny matrices and general rectangular matrices that both minimize communication, and are as stab…
Communication-optimal parallel and sequential QR and LU factorizations
James Demmel, Laura Grigori, Mark Hoemmen +1
We present parallel and sequential dense QR factorization algorithms that are both optimal (up to polylogarithmic factors) in the amount of communication they perform, and just as…
Communication-optimal parallel and sequential QR and LU factorizations: theory and practice
James Demmel, Laura Grigori, Mark Hoemmen +1
We present parallel and sequential dense QR factorization algorithms that are both optimal (up to polylogarithmic factors) in the amount of communication they perform, and just as…
