Triana Generations

This paper discusses the Triana workflow system within the context of the workflow community at large. It provides a brief background for Triana and discusses the ways in which it is has been used in the past for serial as well as distributed tasks. A description of the Triana distributed architecture is given followed by a discussion of its key features, including its user interface and its ability to work simultaneously in heterogeneous distributed environments. The high-level Grid and service-based interfaces that enable this support are outlined along with their corresponding bindings to the underlying middleware, such as WSPeer, Jxta, P2PS, Globus and Web and WS-RF services. New directions are outlined within the peer-to-peer context, followed by a description of two current P2P application domains and two collaborations that provide distributed P2P simulations for testing P2P overlays for use in massively distributed processing and searching, before deployment.
