Distributed convergence detection based on global residual error under asynchronous iterations

Frédéric Magoulès, Guillaume Gbikpi-Benissan

Convergence of classical parallel iterations is detected by performing a reduction operation at each iteration in order to compute a residual error relative to a potential solution…

Asynchronous iterations of HSS method for non-Hermitian linear systems

Guillaume Gbikpi-Benissan, Qinmeng Zou, Frédéric Magoulès

A general asynchronous alternating iterative model is designed, for which convergence is theoretically ensured both under classical spectral radius bound and, then, for a classical…

Resilient asynchronous primal Schur method

Guillaume Gbikpi-Benissan, Frédéric Magoulès

This paper introduces the application of the asynchronous iterations theory within the framework of the primal Schur domain decomposition method. A suitable relaxation scheme is de…

Asynchronous multiplicative coarse-space correction

Guillaume Gbikpi-Benissan, Frédéric Magoulès

This paper introduces the multiplicative variant of the recently proposed asynchronous additive coarse-space correction method. Definition of an asynchronous extension of multiplic…

Accurate Coarse Residual for Two-Level Asynchronous Domain Decomposition Methods

Guillaume Gbikpi-Benissan, Frédéric Magoulès

Recently, asynchronous coarse-space correction has been achieved within both the overlapping Schwarz and the primal Schur frameworks. Both additive and multiplicative corrections h…

JACK2: a new high-level communication library for parallel iterative methods

Guillaume Gbikpi-Benissan, Frederic Magoules

In this paper, we address the problem of designing a distributed application meant to run both classical and asynchronous iterations. MPI libraries are very popular and widely used…
