Mathematics and Computer Science Division
"Developments in Parallel File System Techniques and Scientific I/O Libraries"

DATE: July 18, 2007
TIME: 1:30pm
SPEAKER: Avery Ching, Northwestern University
LOCATION: Building 221, Conference Room A-216, Argonne National Laboratory
HOST: Rob Ross

Description:
Large-scale computational simulations are an important tool for science. Scientific simulation usually requires parallel storage systems for efficiently handling hundreds of Gigabytes to Petabytes of data. The rich I/O interfaces available in high-level I/O libraries, such as NetCDF or HDF5, and middleware I/O libraries, such as MPI-IO, provide significant opportunities to optimize noncontiguous data access patterns. In this talk, we detail several techniques in both the middleware and file system for improving noncontiguous I/O access.
