PDSI Events @ UCSC

Petascale Data Storage Institute @ UC Santa Cruz

With the emergence of petabyte-scale shared file systems, organizing the files in manner that allows users to easily locate their data in traditional hierarchies will become increasingly difficult. One approach to solve this problem is to simply avoid imposing hierarchies on the files on the files and instead allow users to simply search for the files they are interested in. SSRC researchers are developing approaches that leverage the rich metadata that already exists within the stored files to create views that are customized to each user of the shared system.

The Storage Systems Research Center (SSRC) is part of the Petascale Data Storage Institute, a Department of Energy-funded institute exploring techniques to make high-performance storage faster and more usable.

PDSI Research at UC Santa Cruz

PDSI topics the SSRC is investigating include security for petascale storage, new approaches to distributed metadata, the use of storage class memories in high-performance systems, and archival storage.

PDSI Organization

The Petascale Data Storage Institute is led by Carnegie Mellon University. The PDSI institutions are:

  • Carnegie Mellon University
  • Lawrence Berkeley National Laboratory and the National Energy Research Scientific Computing Center
  • Los Alamos National Laboratory
  • Oak Ridge National Laboratory
  • Pacific Northwest National Laboratory
  • Sandia National Laboratory
  • University of California, Santa Cruz
