Ph.D. Dissertation:

“Network Transparency in Wide Area Collaborations”. To meet the demands of large-scale data sharing in Grid computing, I developed a replicated file system that allows users and applications to access widely distributed data as simple and efficiently as they access them locally. The file system includes a naming scheme that supports a global name space and location independent naming, which facilitates data sharing, distribution, and management. It uses a replication protocol that supports mutable (read/write) replication with strong consistency guarantees, enabling the re-use of existing software in Grid computing. I have implemented the design in NFSv4 (based on the latest version in Linux 2.6.16 kernel), the new standard Internet distributed file system protocol, and evaluate the performance of the system with scientific applications and Grid benchmarks. These studies demonstrate that a replicated file system framework addressing the data access and storage requirements of emerging global collaborations is vital and feasible.
