"In the CX project, we are designing an open, extensible Computation eXchange that can be instantiated privately, within a single organization (e.g., a university, distributed set of researchers, or corporation), or publicly as part of a market in computation, including charitable computations (e.g., AIDS or cancer research, SETI). Application-specific computation services constitute one kind of extension, in which computational consumers directly contact specialized computational producers, which provide computational support for particular applications.
The system must enable application programmers to design, implement, and deploy large computations, using computers on the Internet. It must reduce human administrative costs." (http://www.cs.ucsb.edu/projects/cx/CX_overview.html)
