Augstas veiktspējas skaitļošanas izmantošana skaitliskā modelēšanā/Use of High Performance Computing in Numerical Simulations

Thursday 22 Feb 2024, 09:30 → 16:00 Europe/Riga

House of Science / Zoom (Hybrid)

Jānis Virbulis (Institute of Numerical Modelling, University of Latvia)

LV: Konferences sekcija rada iespēju izcelt atklājumus, kas veidojušies pielietojot skaitliskās modelēšanas un augstas veiktspējas skaitļošanas iespējas Latvijas Universitātē un tās partnerinstitūcijās. Vienlaikus tā atvērta arī pētniecībai, kurā skaitliskās modelēšanas pielietojums vēl nav izveidots, ja ieraugāmi ieguvumi, ko skaitliskās modelēšanas metodes varētu atklāt tēmas izpētē nākotnē. Šī sekcija tiek organizēta sadarbībā ar Latvijas HPC kompetences centru.

ENG: The space for sharing the inspiring research stories achieved using the numerical modelling and high performance computing in University of Latvia and in its partner institutions. The conference section is open also to the research presentations where the benefits regarding the implementation of the numerical modelling for the scientific  discoveries can be seen in the future. This section is co-organized in collaboration with the HPC Competence Centre of Latvia.

Language: English

Chair: lead reasercher Jānis Virbulis
