In this paper, we present an Open Grid Services Architecture (OGSA)-based decentralized allocation enforcement system, developed with an emphasis on a consistent data model and ea...
A class of trust-region methods is presented for solving unconstrained nonlinear and possibly nonconvex discretized optimization problems, like those arising in systems governed by...

: A large variety of emerging Computational Grid applications require versioning services to support effective management of constantly changing datasets and implementations of dat...
The open and anonymous nature of a P2P network makes it an ideal medium for attackers to spread malicious content. In this paper, we propose a reputation-based trust management sy...
Manual management of public key credentials can be a significant and often off-putting obstacle to Grid use, particularly for casual users. We describe the Portal-based User Regis...
