HOCs: Higher-Order Components for Grids
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
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.
