Scheduling Data Placement Activities in Grid
(University of Wisconsin-Madison Department of Computer Sciences, 2003)
Todays scientific applications have huge data requirements, and these requirements continue to increase drastically every year. Furthermore, these data are generally accessed by many users from all across the country, or ...
The Interaction of Failure and Performance in a Migratory File Service
(University of Wisconsin-Madison Department of Computer Sciences, 2003)
We present the design, implementation, and evaluation of a Migratory File Service (MFS), a system designed to exploit semantic knowledge of workloads and user expectations to improve performance and handle failures effectively ...
Security Policy Reconciliation in Distributed Computing Environments
(University of Wisconsin-Madison Department of Computer Sciences, 2004)
A major hurdle in sharing resources between organizations is heterogeneity. Therefore, in order for two organizations to collaborate their policies have to be resolved. The process of resolving different policies is known ...
DiskRouter: A Flexible Infrastructure for High Performance Large Scale Data Transfers
(University of Wisconsin-Madison Department of Computer Sciences, 2004)
The steady increase in data sets of scientific applications, the trend towards collaborative research and the emergence of grid computing has created a need to move large quantities of data over wide-area networks. The ...
Parrot: Transparent User-Level Middleware for Data-Intensive Computing (Revised February 2004)
(University of Wisconsin-Madison Department of Computer Sciences, 2004)
Originally submitted in 2003.
Distributed computing continues to be an alphabet-soup of services and protocols for managing computation and storage. To live in this environment, applications require middleware that can ...
Migratory File Services for Scientific Applications
(University of Wisconsin-Madison Department of Computer Sciences, 2002)
Building Data-Pipelines for High Performance Bulk Data Transfers in a Heterogeneous Grid Environment
(University of Wisconsin-Madison Department of Computer Sciences, 2003)
The drastic increase in the data requirements of scientific applications combined with an increasing trend towards collaborative research has resulted in the need to transfer large amounts of data among the participating ...
Distributed Policy Management and Comprehension with Classified Advertisements
(University of Wisconsin-Madison Department of Computer Sciences, 2003)
Distributed systems present new challenges to resource management, which cannot be met by conventional systems that employ relatively static resource models and
centralized allocators. Matchmaking paradigms based on ...
The Case for Sparse Files
(University of Wisconsin-Madison Department of Computer Sciences, 2003)
