Coming Events
February 27, 2008 - Petascale Data Storage BoF Session at FAST '08
The Petascale Data Storage Institute is a DOE-funded collaboration of three universities and five national labs with the objective of anticipating the challenges of data storage for computing systems operating in the peta-operations per second to exa-operations per second and working toward the resolution of these challenges in the community as a whole. An important part of our agenda is outreach to other researchers and practitioners to share our resources and gather better understanding of the petascale issues ahead from all.
February 23, 2008 - Parallel I/O for Extreme-scale Platforms
The ORNL Future Technologies group with personnel from the ORNL National Center for Computational Sciences are to give a tutorial on parallel I/O for extreme-scale platforms such as the Cray XT, IBM Blue Gene, and ultra-scale Linux clusters. We will share our experiences and lessons learned from characterizing and optimizing I/O on these platforms, and discuss directions and issues that need to be addressed for I/O at the unprecedented scale needed for petaflop and even exaflop systems. Join us on February 23, 2008 in Salt Lake City for this enlightening, in-depth discussion. One of the tutorial presenters, Dr. Phil Roth, of ORNL, is a PDSI Principal Investigator.

PDSI Overview
Petascale computing infrastructures for scientific discovery make petascale demands on information storage capacity, performance, concurrency, reliability, availability, and manageability. The last decade has shown that parallel file systems can barely keep pace with high performance computing along these dimensions; this poses a critical challenge when petascale requirements are considered. The Petascale Data Storage Institute will focus on the data storage problems found in petascale scientific computing environments, with special attention to community issues such as interoperability, community buy-in, and shared tools. Leveraging experience in applications and diverse file and storage systems expertise of its members, the institute allows a group of researchers to collaborate extensively on developing requirements, standards, algorithms, and development and performance tools. Mechanisms for petascale storage and results will be made available to the petascale computing community. The institute will hold periodic workshops and develop educational materials on petascale data storage for science.
The Petascale Data Storage Institute is a collaboration between researchers at Carnegie Mellon University, National Energy Research Scientific Computing Center, Pacific Northwest National Laboratory, Oak Ridge National Laboratory, Sandia National Laboratory, Los Alamos National Laboratory, University of Michigan, and the University of California at Santa Cruz.
