Abstract:The necessity of dealing with uncertainties is growing in many different fields of science and engineering. Due to the constant development of computational capabilities, current solvers must satisfy both statistical accuracy and computational efficiency. The aim of this work is to introduce an asynchronous framework for Monte Carlo and Multilevel Monte Carlo methods to achieve such a result. The proposed approach presents the same reliability of state of the art techniques, and aims at improving the computati… Show more
“…A critical paradigm to support was the relaxation of global synchronizations required between simulations belonging to different levels of the MLMC algorithm. 12 In addition, the support for MPI tasks was very naive at that time and required extensions to support more complex data layouts.…”

“…The computational efficiency of the joint use of XMC, Kratos and PyCOMPSs has already been demonstrated, and optimal strong scalability was ensured up to 128 nodes (6144 central processing units (CPUs)) (Tosi et al, 2021a).…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
