Parallelization and scalability analysis of inverse factorization using the Chunks and Tasks programming model

Anton G. Artemov, Elias Rudberg, Emanuel H. Rubensson

We present three methods for distributed memory parallel inverse factorization of block-sparse Hermitian positive definite matrices. The three methods are a recursive variant of th…

Localized inverse factorization

Emanuel H. Rubensson, Anton G. Artemov, Anastasia Kruchinina +1

We propose a localized divide and conquer algorithm for inverse factorization $S^{- 1} = Z Z^{*}$ of Hermitian positive definite matrices $S$ with localized structure, e.g. exponential…
