BIRCH: an efficient data clustering method for very large databases
A data clustering method named BIRCH (Balanced Iterative Reducing and Clustering using Hierarchies) is presented, and it is demonstrated that it is especially suitable for very large databases.
Condor-a hunter of idle workstations
The design, implementation, and performance of the Condor scheduling system, which operates in a workstation environment, are presented and a performance profile of the system is presented that is based on data accumulated from 23 stations during one month.
Distributed computing in practice: the Condor experience
The history and philosophy of the Condor project is provided and how it has interacted with other projects and evolved along with the field of distributed computing is described.

- 21 January 1997
An efficient and scalable data clustering method is proposed, based on a new in-memory data structure called CF-tree, which serves as an in- memory summary of the data distribution, and implemented in a system called BIRCH (Balanced Iterative Reducing and Clustering using Hierarchies), and compared with other available methods.

The classified advertisement (classad) matchmaking framework is developed and implemented, a flexible and general approach to resource management in distributed environment with decentralized ownership of resources.
Condor and the Grid
Ready access to large amounts of computing power could be achieved inexpensively with collections of small devices rather than expensive single supercomputers in the 1970s.
Pegasus: Mapping Scientific Workflows onto the Grid
- E. Deelman, J. Blythe, M. Livny
- Computer Science, PhysicsEuropean Across Grids Conference
- 28 January 2004
The Pegasus system that can map complex workflows onto the Grid and takes an abstract description of a workflow and finds the appropriate data and Grid resources to execute the workflow is described.
Examining the Challenges of Scientific Workflows
A recent National Science Foundation workshop brought together domain, computer, and social scientists to discuss requirements of future scientific applications and the challenges they present to current workflow technologies.
