This paper introduces the multiplicative variant of the recently proposed asynchronous additive coarse-space correction method. The definition of an asynchronous extension of …
This paper introduces the application of asynchronous iterations theory within the framework of the primal Schur domain decomposition method. A suitable relaxation scheme is …
In this paper, we tackled the convergence detection problem arisen from the absence of synchronization during asynchronous iterative computation. We showed that, when one …
Recently, asynchronous coarse-grid correction has been achieved within additive Schwarz- type and primal Schur domain decomposition frameworks. Both additive and multiplicative …

We propose and analyze a mixed precision parareal algorithm that uses for the fine propagator and the coarse propagator a high precision and a low, respectively. This …

For the well known parareal algorithm, we formulate and analyse a novel class of parareal exponential schemes with improved uniform accuracy for highly oscillatory system q¨+ 1 ε 2 …
This paper presents a parallel implementation for the Optimal Transportation Meshfree (OTM) method on large CPU clusters. Communications are handled with the Message …
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 …

Compared with arithmetic operation, communication cost is often the bottleneck on modern computers, and thus should be paid increasing attention when choosing algorithms. Lagged …
