Workflow execution on large-scale heterogeneous distributed computing systems, such as Grids, requires a complex coordination. Activities of complex workflow patterns must be matched with entities of the computing system that possesses highly dynamic properties. We pinpoint the key concept of such workflow coordination as actions according to actual and local conditions - analogously to chemical reactions. Modeling workflow enactment as molecules and reactions, formalized in the nature inspired gamma-calculus, yielded an autonomously evolving, distributed, decentralized coordination model that can adapt to a dynamically changing environment.
