Location-Transparent Naming in Grid Computing Using Legion-G

∗ This work is supported in part by the National Science Foundation under the Next Generation Software Program grant EIA-9974968, the NPACI program of the National Science Foundation, the NASA Information Power Grid (IPG) program, and a grant from the Microsoft Corporation. Globus [1] is a powerful toolkit but lacks location transparency in its naming system, due to a reliance on URLs. In pract...

An Innovative Product for Space Mission Planning

This paper describes MEXAR2, a software tool that is currently used to synthesize the operational commands for data downlink from the on-board memory of an interplanetary space mission spacecraft to the ground stations. The tool has been in daily use by the Mission Planning Team of MARS EXPRESS at the European Space Agency since early 2005. Goal of this paper is to present a quick overview of h...

The Legion support for advanced parameter-space studies on a grid

Parameter-space studies involve running a single application several times with different parameter sets. Since the jobs are mutually independent, many computing resources can be recruited to conduct an entire study in a distributed manner. Parameter-space studies are attractive applications for grids, which are networked collections of computing and other resources. Legion is a grid infrastruc...

The Core Legion Object Model

This document describes the core Legion object model. The model specifies the composition and functionality of Legion’s core objects—those objects that cooperate to create, locate, manage, and remove objects from the Legion system. The model reflects the underlying philosophy and objectives of the Legion project. In particular, the object model facilitates a flexible extensible implementation, ...
