Petascale Data Storage Workshops

WORKSHOP ABSTRACT

Petascale computing infrastructures make petascale demands on information storage capacity, performance, concurrency, reliability, availability, and manageability. This one-day workshop focuses on the data storage problems and emerging solutions found in petascale scientific computing environments, with special attention to issues in which community collaboration can be crucial, problem identification, workload capture, solution interoperability, standards with community buy-in, and shared tools. This workshop seeks contributions on relevant topics, including but not limited to: performance and benchmarking results and tools, failure tolerance problems and solutions, APIs for high performance features, parallel file systems, high bandwidth storage architectures, wide area file systems, metadata intensive workloads, autonomics for HPC storage, virtualization for storage systems, data-intensive and cloud storage,archival storage advances, resource management innovations, etc.

Submitted extended abstracts (up to 5 pages, due Sept. 18, 2009) will be peer reviewed for presentation and publication on www.pdsi-scidac.org and in the ACM digital library.

Other Workshops & Panels of Interest at SC09

pNFS: Parallel Storage Client and Server Development Panel Update

Primary Session Leader:
Joshua Konkle (NetApp)

Birds-of-a-Feather Session Tuesday, 05:30PM - 07:00PM
Room E143-144

This panel will appeal to Virtual Data Center Managers, Database Server administrators, and those that are seeking a fundamental understanding pNFS. This panel will cover the four key reasons to start working with NFSv4 today. Explain the storage layouts for parallel NFS; NFSv4.1 Files, Blocks and T10 OSD Objects. We’ll engage the panel with a series of questions related to client technology, storage layouts, data management, virtualization, databases, geoscience, video production, finite element analysis, MPI-IO client/file locking integration, data intensive searching, etc . You’ll have an opportunity to ask detailed questions about technology and panel participant plans from SNIA’s NFS Special Interest Group which is part of the Ethernet Storage Forum.
