Clusters Home

Context

Nef is Inria Sophia Antipolis Méditerranée research center multidomain scientific experimentation infrastructure for computation, storage and visualisation.

The platform relies on a cluster computing approach (several generations of high performance servers are combined to provide heterogeneous parallel architecture), fast network interconnect, high capacity storage and interconnection to Inria Sophia interactive visualisation platform.

Nef is a member infrastructure the UCA OPAL distributed computation mesocentre.

Nef is operated and originaly funded by Inria. Nef now also gratefully benefits from UCA and UCA^jedi IDEX funding.

Nef gratefully benefits from CPER 2015-2020 funding from Région Sud Provence Alpes Côte d'Azur, French MESRI (Ministère de l'Education Nationale, de l'Enseignement Supérieur et de la Recherche) and CASA (Communauté d'Agglomération de Sophia Antipolis).

Usage

The platform is open for members of all Inria teams. Accounts can also be opened for academic and corporate partners of Inria Sophia research center teams.

It can be used for both parallel computations, GPU computation and sequential jobs, etc.
