Applications for ultrascale systems
Margenov, Svetozar; Rauber, Thomas; Atanassov, Emanouil; Almeida, Francisco; Blanco, Vicente; Čiegis, Raimondas; Cabrera, Alberto; Frasheri, Neki; Harizanov, Stanislav; Kriauzienė, Rima; Rünger, Gudula; San Segundo, Pablo; Starikovičius, Vadimas; Szabo, Sandor; Zavalnij, Bogdan (Ultrascale computing systems: Poskyris: 6.2. On parallel algorithms for the numerical solution of problems with fractional powers of elliptic operators, 2019)The needed reformulation of algorithms and applications from different areas of research toward their usage for ultrascale systems and platforms has to address different challenges that arise from the different application ... -
High-order two and three level schemes for solving fractional powers of elliptic operators
Čiegis, Raimondas; Vabishchevich, Piotr (Numerical mathematics and advanced applications ENUMATH 2019: European conference, Delft University of Technology, Egmond aan Zee, The Netherlands, September 30 - October 4, 2019, 2021)In this paper we develop and investigate numerical algorithms for solving the fractional powers of discrete elliptic operators with Vh a finite element or finite difference approximation space. Our goal is to construct ... -
Numerical simulation of heat transfer in underground electrical cables
Jankevičiūtė, Gerda; Čiegis, Raimondas; Tumanova, Natalija; Bugajev, Andrej (Progress in industrial mathematics at ECMI 2014 : Conference proceedings: European Consortium for Mathematics in Industry, 2016)The aim of this project is to develop a virtual modelling tool which can be used to construct optimal design of power transmission lines and cables. They should meet the latest power transmission network technical and ... -
Parallel algorithms for parabolic problems on graphs in neuroscience
Tumanova, Natalija; Čiegis, Raimondas (High-performance computing on complex environments, 2014)Three parallel numerical algorithms have been developed for solution of parabolic problems on graphs in neuroscience, suitable for structures containing closed loops. This chapter investigates parallel versions of implicit ...
