Advances in computational, storage and network technologies as well as middle ware such as the Globus Toolkit allow scientists to expand the sophistication and scope of data-intensive applications. These applications produce and analyze terabytes and petabytes of data that are distributed in millions of files or objects. To manage these large data sets… (More)
The OGSA Data Replication Services (OREP) Working Group of the Global Grid Forum has been working to develop standards for OGSI-compliant replica location services. This paper describes an implementation of the ReplicaSet service based on the OREP specification and evaluates the performance of different semantic enforcement policies.
We present the implementation and performance of a ReplicaSet service based on the specification developed in the OGSA Data Replication Services (OREP) Working Group of the Global Grid Forum. This standard is based on the open grid services infrastructure. The ReplicaSet service aggregates information about replicated data items and enforces policies for… (More)
