Best paper de DCABES 2016 attribué à Camille Coti

Camille Coti a reçu le best paper à DCABES 2016 pour son article Scalable, Robust, Fault-Tolerant Parallel QR Factorization.

Résumé : In this paper, we are presenting QR factorization algorithms that can tolerate process crashes and soft errors (bit flips). Our algorithms take advantage of structural properties of a QR factorization algorithm referred to as communication-avoiding. We show that, exploiting these properties, our resilient, robust algorithms modify the communication pattern of the computation but do not add any significant computation in the critical path.
