Join us November 30th 2026 at "Couvents des Cordeliers", in the beautiful Latin Quarter of Paris

10th anniversary edition of the Workshop

Performance and Scalability of Storage Systems

Per3S is a french workshop centered on performances of storage system and all the issues related to storage at scale

The terminology used in Per3S for storage includes HPC systems as well as Cloud architectures, the common point between both being scalability. Presentations and talks focus in application, system or architecture. This 10th edition aims to gather during one day researchers from academia and industry, experimented or junior, storage users and customers with the sole purpose to exchange and foster the community.

Per3S 10th Anniversary Edition

Per3S is a workshop aiming to bring together the scientific and technological storage community to discuss and address issues and challenges associated to performance and data operations at scale. These topics cover HPC storage as well as Cloud-oriented architectures, both sharing the need for extreme scale.

Per3S fully encourages young researchers to present their work by submitting an abstract. The abstract can relate to an original work, on-going work, with fresh problems/solutions, or one already submitted and/or accepted in an international conference in order to be the subject of discussions.

Modality of submissions

Communications and submissions may be made either in French or in English.

Important dates

Submission of abstracts from October 15th until November 23rd
Two paragraph, a short bio and title of the poster to be sent to: per3s.contact@gmail.com
Notifications are made to authors within 3 days of submission
Workshop on November 30th

50 Participants

Previous editions of Per3S have successfully fostered a community of researchers both from academia and industry working on storage technologies. The audience is around 50 persons.

3 sessions

The program is organized around 3 sessions: one dedicated to Cloud, Storage technologies and data management, the second sessions is focused on poster for interactive discussion, and the last and third session is centered on HPC storage technologies and Lustre in particular.

12 talks, 8 Posters

Each posters is coming with an additional Flash-Presentation. Get within a single day a comprehensive overview of the storage activities in France.
