The context

EDF R&D runs a substantial number of numerical simulations and maintains a variety of on-premises High-Performance Computing (HPC) infrastructures, including Slurm clusters such as CRONOS and SELENA. In the meantime, EDF R&D had a deficit of a few million computing hours.

Aneo built an elastic HPC solution on AWS for EDF R&D, integrated with a ParallelCluster overlay provided by UCit. The setup enables project-based overflow capacity by adding on-demand compute resources, while also improving resilience in the event of internal infrastructure outages. In addition, EDF R&D also aimed to equip its researchers with advanced, on-demand state-of-the-art computing resources like the latest CPUs and GPUs.

Challenge

Maintain a consistent user experience while allowing EDF to go beyond the traditional static HPC cluster setups.
Provide flexible HPC deployments while keeping with EDF’s strict security requirements in terms of user access and data management.
Accompany researchers in their discovery of what the new platform could do for them.

Impact

Possibility to deploy specialized, targeted and possibly ephemeral HPC Clusters on a project-by-project basis or other relevant criteria.
Ability to expand EDF R&D HPC capacity to absorb the charge of traditional busy periods at the middle and end of the year.
A platform that can be RUN by less than one FTE year-round without any impact in up-time or support quality.
