GRID Architecture through a Public Cluster

TL;DR

This paper presents a novel architecture for public clusters that integrates web-services with the Globus Toolkit, enabling blocks within the cluster to authenticate users and join multiple global grid collaborations more easily.

Contribution

Introduces a web-service extension to the Globus Toolkit that facilitates authentication and dynamic block mapping, enhancing grid integration for public clusters.

Findings

Enables blocks in public clusters to join multiple grids.

Improves authentication and resource mapping processes.

Supports flexible and scalable grid collaborations.

Abstract

An architecture to enable some blocks consisting of several nodes in a public cluster connected to different grid collaborations is introduced. It is realized by inserting a web-service in addition to the standard Globus Toolkit. The new web-service performs two main tasks : authenticate the digital certificate contained in an incoming requests and forward it to the designated block. The appropriate block is mapped with the username of the block's owner contained in the digital certificate. It is argued that this algorithm opens an opportunity for any blocks in a public cluster to join various global grids.
