HOCs: Higher-Order Components for Grids




Abstract
This talk deals with the problem of application programming for emerging grids that combine heterogeneous data and computational resources via the Internet. We argue that grid programming is still too complex because of the big gap between the currently used grid middleware, e.g., the Globus Toolkit, and the application level.

We propose to bridge this gap by using Higher-Order Components (HOCs) -- recurring patterns of parallel behaviour that are provided to the user as program building blocks with pre-packaged implementation. The presentation is illustrated with a case study of computing fractal images. Our experiments demonstrate that HOCs simplify grid application programming significantly, without serious performance loss.
