A distributed-memory parallel implementation of the sparsified QR factorization algorithm using the TaskTorrent runtime system. This repository provides efficient QR factorization for large sparse ...

Abstract: 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 ...

We present optimal parallel QR factorization algorithms with reduced communication overhead. QR factorization is widely applied to solve various problems in numerical linear algebra. Our focus is on ...

We present an algorithm to generate complete evolutionary profiles that represent the topology of the molecular phylogenetic tree of the homologous group. The method, based on the multidimensional QR ...
