Title: Grid Information Retrieval System for Dynamically
Reconfigurable Virtual Organization

Authors/editors:  Yangwoo Kim

Abstract:

Under foundational precepts of Grid computing, two important
requirements that all Grid application systems should satisfy are to
accommodate the dynamic nature of Virtual Organizations (VOs), and
to enforce different levels of security among different VOs.  For
the research described in this document, we developed two different
use-case scenarios addressing the two requirements, and then showed
how the requirements can be met by implementing a Grid information
retrieval (GIR) system prototype. The dynamic nature of VO applies
not only to increasing and decreasing number of users, but also to
the dynamically changing requirement of computing power among the
different subcomponents that consist in overall system
configuration.  This implies that a request to increase computing
power by a certain subcomponent can be satisfied by other idling
subcomponents taking advantage of overall system flexibility.

This document describes how we implemented a Grid IR system using VO
and security mechanisms provided by Globus toolkit 3.0, and shows
how GIR system scalability and security can be improved for dynamic
VOs.  In order to manage different VOs, we implemented VO management
service (VOMS), and registered it to Globus as an additional
service.
