Hemera

Overview

Héméra is a INRIA large scale initiative , started in 2010, that aims at demonstrating ambitious up-scaling techniques for large scale distributed computing by carrying out several dimensioning experiments on the Grid’5000 infrastructure, at animating the scientific community around Grid’5000 and at enlarging the Grid’5000 community by helping newcomers to make use of Grid’5000. It is not restricted to INRIA teams.

Publications around Grid'5000 are available as a HAL collection.
