3rd International Workshop on the Lustre Ecosystem: Support for Deepening Memory and Storage Hierarchy

By jfranklin

Hanover, Maryland
July 25-26, 2017

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

Fuller details can be found in the 2.9 wiki page (including the change log and test matrix)

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.

Please log any issues found in the issue tracking system 

Thanks to all those who have contributed to the creation of this release.

OpenSFS Reinvents Itself with a Focus on User Needs

By jfranklin

November 11, 2016

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:

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.
