Information
Lustre, the leading open-source and open-development parallel file system for HPC and AI was in use at 8 of the world’s TOP10 supercomputers in November 2025 including the TOP3 systems El Capitan, Frontier and Aurora as well as four European TOP10 supercomputers HPC6, Alps, LUMI and Leonardo.
Beyond the TOP10 Lustre is one of the most widely adopted technologies in HPC around the world as it is in use at over 60% of the TOP100 systems.
Lustre was historically driven mainly by U.S. National Labs but has widened its scope beyond its traditional stronghold to include high-end AI/ML and extreme cloud infrastructures. It is a community-developed technology with contributors from around the world. Lustre clients are available for broadly deployed instruction set architectures (ISAs) such as x86, Power and ARM.
It is also widely used across mid- and small-scale HPC-systems with continued adoption attributable to its availability as open source and its stability. Major cloud vendors AWS, GCP, OCI and Azure all have Lustre offerings.
Lustre is suitable for a wide variety of workloads. It is capable of handling both small and large IO segments and files. It has an attainable starting point and offers a cost-effective option for scalable, high-performance HPC storage on a multitude of system designs, network topologies. It continues to be one of the most widely adopted technologies in HPC around the world.
Vital to the technology is the Lustre community that continues to drive Lustre forward. As Lustre has an established true open-source and open-development model, end users, developers and solution providers regularly come together through the worldwide EOFS and OpenSFS communities both being present at the BoF.
This community development model has resulted in significant new features, improved stability and broader adoption.
At this BoF, Lustre developers, administrators, and solution providers will also discuss technical details of recent developments, such as the recent Lustre 2.16 and 2.17 releases, continuing LTS support for Lustre 2.15, as well as issues, new challenges and corresponding opportunities.
On the other side we will also discuss emerging use cases like the scalability challenges associated with the growing number of exascale systems. We will explore these cases and discuss the Lustre roadmap for meeting the new requirements that they present.
A key part related to Lustre operations will be the discussion of best practices, optimizing file system access, metrics, and other Lustre-related items.
Looking beyond the current releases the community will discuss planned features for Lustre 2.18 like Client Data Compression, Metadata Writeback Cache, Erasure Coding and RHEL10 Server support.
