A 3D Parallel Algorithm for QR Decomposition
Grey Ballard, James Demmel, Laura Grigori +2
Interprocessor communication often dominates the runtime of large matrix computations. We present a parallel algorithm for computing QR decompositions whose bandwidth cost (communi…
Enhancing the scalability and load balancing of the parallel selected inversion algorithm via tree-based asynchronous communication
Mathias Jacquelin, Lin Lin, Nathan Wichmann +1
We develop a method for improving the parallel scalability of the recently developed parallel selected inversion algorithm [Jacquelin, Lin and Yang 2014], named PSelInv, on massive…
Multilevel communication optimal LU and QR factorizations for hierarchical platforms
Laura Grigori, Mathias Jacquelin, Amal Khabou
This study focuses on the performance of two classical dense linear algebra algorithms, the LU and the QR factorizations, on multilevel hierarchical platforms. We first introduce a…
