We are happy to announce that NET4EXA was represented at the Lustre Administrators and Developers (LAD) 2025 conference in Toulouse, France, on 30 September – 1 October.

Quentin Boyer (Eviden), on behalf of NET4EXA, presented the initial design of the new Lustre Newtwork Driver (LND) developed for BXIv3. This work is part of Task 4.3: Storage I/O in the NET4EXA project and focuses on providing necessary support for popular storage abstractions and services over BXIv3 networks.

During his talk, Quentin highlighted several key aspects that will enable the LND to take advantage of the performance of BXIv3:

               *   Implementation of immediate and bulk message handling for efficient Get/Put operations.

               *   Flow control mechanisms to avoid resource exhaustion and ensure reliable high-throughput transfers.

               *   Optimized handling of multiple transmission and reception contexts for scalable performance.

Work will continue over the coming months with improvements and optimizations to the LND that will allow the hardware performance to be fully exploited.

This work demonstrates NET4EXA’s continued contribution to high-performance storage and I/O for exascale computing, and its active role in the Lustre and Network community.

From 10 to 12 June 2025, the NET4EXA team attended ISC High Performance in Hamburg, Germany. The project was featured at the EuroHPC Joint Undertaking booth, alongside other European initiatives. We thank the JU for offering us this opportunity to be present at the event.

Anton Daumen gave a presentation introducing NET4EXA and highlighting the key challenges the project addresses within the HPC ecosystem.

From 18 to 20 March 2025, the NET4EXA team was in Krakow, Poland, for the EuroHPC Summit 2025. This edition was a great success, breaking records in terms of participation! We took part in the poster session and had the opportunity to connect with many actors of the European HPC community. A valuable occasion to showcase our project, strengthen our visibility, and build new collaborations across the EuroHPC ecosystem.

The NET4EXA consortium partners gathered in Rome for a face-to-face meeting hosted at the University of Rome Sapienza, thanks to the kind invitation of INFN Sezione di Roma. A big thank you to our hosts for making this meeting a success! It was a great opportunity to work together in person, strengthen our collaboration, and push the project forward. We’re already looking forward to the next face-to-face meeting, which will be hosted by FORTH in Greece!

The EuroHPC JU issued a Press Release announcing NET4EXA on 13 December 2024.

Supported by EuroHPC JU funding, the NET4EXA research and innovation project aims to develop innovative interconnect technologies, which are high-speed systems that enable seamless communication between supercomputers components.

The NET4EXA consortium partners spent two days together to launch the project. These two days enabled the team to get to know each other better, exchange ideas and clarify many aspects of the project in order to get their work off to the best possible start. Looking forward to the next steps – and the next face to face meeting!

Project NET4EXA is starting on 1st September 2024. The project funded by the EuroHPC JU will develop and demonstrate the next generation of European Interconnect, ready for uptake in exascale and post exascale HPC and AI systems, leveraging proven European interconnect technology (BXI), in full coordination with other EU-funded initiatives.

Stay tuned!
