“…The convergence of the applied PCG method is then smoother and faster. The arising large-scale systems of linear equations are processed by parallel solvers based on the PCG method, with stabilization in the singular case [11]. Most of the computations were performed on the SGI cluster Salomon [9], only the results of the performance comparison study and scalability tests were obtained with the aid of other available High Performance Computing (HPC) computers:…”

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.
