Heterogeneous Adaptable Reconfigurable Networked Systems (HARNESS) is an experimental metacomputing system build around the services of a highly customizable and reconfigurable, distributed virtual machine (DVM) that can run on anything from a Supercomputer to a PDA. HARNESS is built on three key areas of research: Parallel Plug-in interface, Distributed Peer-to-Peer Control, and Multiple DVM Collaboration.

HARNESS is a collaborative effort between ORNL, University of Tennessee, and Emory University. This site's primary focus is on ICL's contributions to HARNESS.
