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.
