Remote visualization of large scale fast dynamic simulations in a HPC context

Autor: Isabelle Bertron, Fabien Vivodtzev

Publikováno v: LDAV

This paper details the conception of a remote and powerful visualization tool intended to be directly used by physicists in order to better understand the physical phenomena in the field of fast dynamics simulations. The goal is to explore large data
