Experiences in Developing a Node of an International Computational Physics Data Grid

The International Lattice Data Grid (ILDG) is an
international collaboration that creates standards to enable
sharing of data produced by Lattice Quantum
ChromoDynamics (QCD) simulations, which are very
computationally expensive. In this paper we summarize
our experiences in developing an Australian node of the
ILDG, including implementing a program to generate
metadata conforming to the QCDml XML schema
developed by the ILDG, storing the metadata in an XML
database, developing metadata catalog and file catalog
services using standard web service interfaces, providing
data download using an SRM interface, and implementing
a web portal to the ILDG. One of the problems we
encountered in this work was that existing metadata
catalog software was not able to meet the requirements of
this project. Although this work is specific to Lattice
QCD data and the ILDG specifications, most of the main
issues in developing the data grid node are quite general
and not specific to the type of data. |
