The Eclipse (Extreme Coherent Light Interaction: Plasma Simulations of the Extreme) Cluster provides computational resources for scientists and engineers who work at the ELI facility as well as for ELI's users who may benefit from computer simulations. From calculations related with radiation activation for design of experimental areas to more detailed aspects of laser-target interactions like laser-plasma phenomena, particle acceleration and such, computer resources such as Eclipse's can help ELI's scientists gain further insights into complex phenomena.

The presence of an in-house cluster also serves as a meeting point for the disciplines of physics (theory and applications), mathematics and computer science, fostering collaborative efforts. From code development to optimization, scientists can gain further experience as they locally improve their tools before deploying them in larger computer centers within the Czech Republic or other places in Europe.
