Users of the supercomputing file system software connect with colleagues, elect officers to OpenSFS board, including IU’s own Ken Rawlings as secretary
Proponents of the Lustre file system, which powers many of the world’s fastest supercomputers, recently gathered last month on the Indiana University Bloomington campus for the annual Open Scalable File Systems Lustre User Group, or LUG, meeting.
LUG is the premier event for the Lustre community and brings together developers, system architects and administrators, and users from all around the world to discuss the current status and future roadmap of Lustre. 2017 has been a transitional year for OpenSFS, the organization dedicated to the success of the Lustre file system, as it moves to a user-led, nonprofit model. In fact, this year marks the first time the LUG meeting was hosted by a user institution.
I’m quite dedicated to Lustre, and am looking forward to helping it become an even more vibrant ecosystem for the global high performance computing community. Ken Rawlings, IU senior systems analyst, on his election to the OpenSFS Board
“We were honored to host LUG17 and its nearly 200 attendees, who traveled to Bloomington from 13 countries and more than 70 institutions,” said Stephen Simms, former OpenSFS president and manager of the High Performance File Systems group at Indiana University. “Everyone at IU did their best to create a successful conference with ample time to connect with colleagues, professionally and socially.”
In addition to workshops and presentations, LUG17 featured an opening reception at IU’s Cyberinfrastructure Building sponsored by DDN, an Intel-sponsored dinner and a movie showing of the 1979 film “Breaking Away” (which was filmed in Bloomington), and a pub crawl sponsored by HGST/WARP.

About PTI The Pervasive Technology Institute at Indiana University is a world-class organization dedicated to the development and delivery of innovative information technology to advance research, education, industry and society. Since 2000, PTI has received more than $50 million from the National Science Foundation to advance the nation’s research cyberinfrastructure. Established by a major grant from the Lilly Endowment, the Pervasive Technology Institute brings together researchers and technologists from a range of disciplines and organizations, including the IU School of Informatics and Computing, the IU Maurer School of Law and the College of Arts and Sciences at Bloomington and University Information Technology Services at Indiana University.
The Lustre parallel file system has been widely adopted by the high-performance computing (HPC) systems as an effective mechanism for managing large-scale storage and I/O resources. Lustre is an open-source parallel file system technology and heavily used by the world’s fastest HPC systems. Lustre achieves unprecedented aggregate performance by parallelizing I/O over file system clients and storage targets at extreme scales. Large-scale checkpoint storage and retrieval, which is characterized by bursty I/O from coordinated parallel clients, has been the primary driver of Lustre development over the last decade.
With the introduction of non-volatile storage technologies, many HPC centers are seeing a proliferation of I/O layers in the end-to-end storage hierarchy that place new demands on Lustre. Effectively managing the node-local memory and these new layers is a new challenge for Lustre and requires new technologies and data management policies to be developed to effectively handle data storage and movement across the I/O stack.
In July of 2017, the 3rd International Workshop on the Lustre Ecosystem will be held in Hanover, Maryland. This workshop series is intended to help explore improvements in the performance, flexibility, and usability of Lustre for supporting diverse application workloads and diverse HPC architectures. The past workshops have helped culminate a discussion on the open challenges associated with enhancing Lustre for diverse applications and architectures, the technological advances necessary, and the associated impacts to the Lustre ecosystem. The 3rd International Lustre Ecosystems Workshop will present a series of invited talks from industry, academia, and US National Laboratories focusing on:
Lustre Node-Local Memory Management
Multilayered Lustre Storage Architectures
Data Flow in Lustre across Multiple I/O Stacks
Data Management and Handling in Lustre across Multiple I/O Stacks
Data Resiliency and Replication Mechanisms in Lustre across Multiple I/O Stacks
Data Provenance in Lustre across Multiple I/O Stacks

This year’s conference is being held in Bloomington, Indiana from May 30-June 2nd, 2017. For more information, visit the LUG 2017 web page.
The LUG Planning Committee is particularly seeking presentations on:
experiences running the newer community releases – 2.8 and 2.9 – in production
experiences using the new features in those releases (DNE2, SSK, UID/GID mapping, etc.)
best practices and practical experiences in deploying, monitoring and operating Lustre
pushing the boundaries with non-traditional deployments
We are pleased to announce that the Lustre 2.9.0 Release has been declared GA and is available for download . You can also grab the source from git
This major release includes new features:
UID/GID Mapping Provides the capability to remap user and group IDs based on node address so as to simplify administration when sharing access between security domains (LU-3291)
Shared Key Crypto Identifies clients/servers and authenticates/encrypts RPCs (LU-3289)
Subdirectory Mounts Offers the option for clients to be able to mount only a defined subset of the filesystem (LU-29)
Server Side Advise and Hinting A Lustre equivalent of fadvise that provides hints to the server about the nature of the data access (willread, dontreed) so that appropriate steps can be taken. (LU-4931)
Large Bulk IO Allows the configuration of larger options to be able to get more efficient network/disk IO . (LU-7990)
Weak Updates Lustre support for weak updates (KMP) has been added. Please note the associated name changes for the RPMs . (LU-5614)
The following are known issues in the Lustre 2.9 Release:
LU-8313 – Deployments using kerberos that have upgraded from an earlier release will need to manually add a–k flag to svcgssd in order to maintain compatibility
LU-8880 – Kerberos does not behave in a consistent manner when deploying in a DNE configuration
These issues are being actively worked and have proposed fixes under testing and review.
BLOOMINGTON, Ind.—Lustre is the file system of choice for the majority of the world’s most powerful supercomputers, helping researchers extract knowledge from data to drive discovery around the world.
Today, the nonprofit organization dedicated to the success of the Lustre file system, Open Scalable File Systems Inc., or OpenSFS, announces organizational changes to give its users—the researchers and scientists who use Lustre every day—more of a say in how OpenSFS moves forward.
One of the first changes affects the OpenSFS board. In late October 2016, a new interim board consisting of users representing academia, business and the US DOE national laboratories was installed and officers were elected.
Members are:
Stephen Simms, Indiana University, President
Sarp Oral, Oak Ridge National Laboratory, Vice President
Rick Wagner, Globus, Secretary
Steve Monk, Sandia National Laboratory, Treasurer
Shawn Hall, BP, Director-at-Large
This board will remain in place until an election at next year’s Lustre User Group meeting, May 30 to June 2, 2017, in Bloomington, Indiana. More information about that meeting can be found here: https://opensfs.org/lug-2017/.
Now the time has come for those who rely most on Lustre—its users—to guide OpenSFS into the future. Stephen Simms, OpenSFS president and manager, high performance file systems, Indiana University
“OpenSFS has reinvented itself as an organization primarily focused on the needs of Lustre users,” said Stephen Simms, OpenSFS president and manager of high performance file systems at Indiana University. “The ramifications of this change is that the organization will be guided by the needs of its users with support from vendors. We encourage both users and vendors to join and participate.”
Other changes include:
A revamped dues structure to encourage wider participation. Members can join for $1,000, and Lustre vendors can join for $5,000
Elected leadership
A user-run Lustre User Group meeting
Opportunities to participate in a requirements gathering exercise connecting our members with vendors
“OpenSFS has accomplished many great things since its inception, providing leadership, labor and capital that have improved Lustre and ensured its place in the HPC ecosystem. Now the time has come for those who rely most on Lustre—its users—to guide OpenSFS into the future,” said Simms.
If you are interested in joining OpenSFS or have questions, please visit: https://opensfs.org/join/ or send an email to [email protected]. OpenSFS will also be attending SC16. Please visit https://opensfs.org/events/ for more information on our event schedule and opportunities to meet with us.
