[Apologies if you receive multiple copies of this call.] **** CALL FOR EXTENDED ABSTRACTS **** International Workshop on The Lustre Ecosystem: Challenges and Opportunities http://lustre.ornl.gov/ecosystem March 3-4, 2015 Annapolis, Maryland, USA **** IMPORTANT DATES **** Note: all submission deadlines are midnight anywhere-on-earth Extended abstracts due: (FINAL DEADLINE EXTENSION) January 30, 2015 Acceptance notification: February 11, 2015 Technical presentations: March 4, 2015 Full papers due: March 13, 2015 **** SCOPE and TOPICS **** Large-scale storage systems are often difficult to manage with complicated interactions between expensive storage hardware, high performance interconnection networks, and client computer systems. The Lustre parallel file system has been widely adopted by high-performance computing (HPC) centers as an effective system for managing large-scale storage resources. Lustre achieves unprecedented aggregate performance by parallelizing I/O over file system clients and storage targets at extreme scales. Today, 7 out of 10 fastest supercomputers in the world use Lustre for high-performance storage. Lustre development has focused on improving the performance and scalability of large-scale scientific workloads. In particular, 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 advent of extreme scale computing and Big Data computing, many HPC centers are seeing increased user interest in running diverse workloads that place new demands on Lustre. In this workshop, we seek contributions that explore improvements in the performance and flexibility of the Lustre file system for supporting diverse workloads. This will be a great opportunity for the Lustre community to discuss the challenges associated with enhancing Lustre for diverse applications, the technological advances necessary, and the associated ecosystem. Specific topics of interest include, but are not limited to: • Workload Characterization • Adaptability and Scalability of Lustre for Diverse Workloads • Resilience and Serviceability of Lustre • Knowledge Provenance in Lustre • Application-driven Lustre Benchmarking • Integrating Big Data Technologies with Lustre • Performance Monitoring Tools for Lustre **** SUBMISSION GUIDELINES **** Authors should electronically submit extended abstracts of previously unpublished work in PDF format. Abstracts may consist of up to 5 US letter-size (8.5 by 11in.) pages, including figures, tables, and references. Submissions should be formatted in IEEE Computer Society conference proceedings style. Accepted abstracts are expected to be expanded into technical papers of at most 10 pages in length, all-inclusive. Full papers will be due the week following the workshop, and will undergo shepherding in preparation for publication in the workshop proceedings. **** ORGANIZING COMMITTEE **** ==PROGRAM CO-CHAIRS == Neena Imam, Oak Ridge National Laboratory, USA Michael Brim, Oak Ridge National Laboratory, USA Sarp Oral, Oak Ridge National Laboratory, USA == TUTORIALS CHAIR == Jason Hill, Oak Ridge National Laboratory, USA **** TECHNICAL PROGRAM COMMITTEE **** Jeremy Archuleta, Oak Ridge National Laboratory, USA Michael Brim, Oak Ridge National Laboratory, USA Jason Hill, Oak Ridge National Laboratory, USA Josh Lothian, Oak Ridge National Laboratory, USA Sarp Oral, Oak Ridge National Laboratory, USA Joel Reed, Oak Ridge National Laboratory, USA Rob Ross, Argonne National Laboratory, USA Nathan Rutman, Seagate, USA Stephen Simms, Indiana University, USA Sudharshan Vazhkudai, Oak Ridge National Laboratory, USA Weikuan Yu, Auburn University, USA
