WP3 Collaborations Summary

The Triana workflow programming environment is used or has been used within a number of projects and research groups, this list is a selection of those projects.

GridOneD

GridOneD is based around the Triana software and is focused on creating open source middleware components for use within Triana and other applications wishing to become grid enabled. GridOneD also extends Triana to supply services for integrating Gravitational Wave search codes. It is using the GAP/GAT and various Gridlab services to implement a production scenario for Grid computing for searching for inspiral binaries and for data mining applications. The second phase of GridOneD is about to start and involves a collaboration between Cardiff University and Manchester University Jodrell Bank Observatory applying existing signal processing techniques in Triana to radio astronomy.

GEO 600

GEO 600 is the main customer for GridOneD. The GEO 600 project aims at the direct detection of gravitational waves by means of a laser interferometer of 600m arm length. Gravitational waves are extremely small ripples in the structure of space-time caused by astrophysical events like supernovae or coalescing binaries.

BiodiversityWorld

BiodiversityWorld is a joint collaboration between the Universities of Cardiff, Reading and Southampton, and the Natural History Museum. BiodiversityWorld is a three-year e-Science Pilot Project funded by the BBSRC to create a GRID-based problem solving environment. This PSE is planned for collaborative exploration and analysis of global biodiversity patterns. Example applications would be modeling species distributions against climate change, conservation prioritising and linking evolutionary changes to past climates. The PSE uses Triana to choreograph custom web services into applications.

DIPSO

Environment for Industrial Design Optimisation (DIPSO) is a proof-of-concept demonstrator to grid-enable and link, two stand-alone software packages (the Modeller and the Optimiser) for modelling and solving complex multi-variate problems in, for example, engineering design or financial services. Integration is achieved through the use of Web Service Definition Language (WSDL) and a Globus-enabled Problem Solving Environment (PSE), Triana. The PSE allows annotation and sharing of results.

FAEHIM

The aim of the FAEHIM (Federated Analysis Environment for Heterogeneous Intelligent Mining) project is to present a data mining toolkit that makes use of Web services composition, with the widely deployed Triana workflow environment.

GEMMS

Grid-Enabled Medical Simulation Services (GEMMS) demonstrates how Grid technologies can be used to transform healthcare and enable Europe to lead that transformation. The GEMSS test-bed renders accessible a multitude of medical computing and resource services in a clinical environment. It provides access to new tools for improved diagnosis, operative planning and surgical procedures in order to create a new way for improved health care. Triana has been used as a workflow tool within the test bed.

Data streaming between Web Services using Inferno

Environmental scientists work with very large datasets on the terabyte scale. It is necessary to handle these datasets in an efficient manner. We are creating a system in which workflows can be composed and run from any Web Service-based workflow engine (e.g. Triana). In these workflows, data are streamed directly from one remote service to another, avoiding the overhead of caching intermediate results on disk. We use the Inferno operating system as a lightweight middleware layer to handle the data streaming. The system also allows us to monitor changes in the state (e.g. the progress) of the remote services.

GENIUS Grid portal

Grid Enabled web eNvironment for site Independent User job Submission (GENIUS} provides Grid Portal functionalities for the EGEE project. GENIUS is examining the use of Triana to provide workflow generation and editing functionality.

The Louisiana Center for Arts and Technology, Louisiana State University (LCAT, LSU)

The DART project (Distributed Audio Rendering using Triana) explores the potential uses of Grid-computing technologies towards sound computation and music synthesis. Our team of researchers is using Triana to control a cluster of 24 Apple Xserve computers in order to demonstrate the potential of distributed audio rendering over a gigabit network. We are developing software objects that will function much like unit generators, software instruments or effects processors that can run simultaneously or in parallel on different machines across a common network. Ultimately, we envision a Web-services or peer-to-peer virtual sound design engine or synthesizer to which anyone on the Web can subscribe, utilize and provide component parts.

Scalable Robust Self-organizing Sensor Network Project (SRSS), NRL

The Scalable Robust Self-organizing Sensor (SRSS) network project is conducting research of communication protocols applicable to creating networks of distributed and self-organizing sensor devices. The have been researching in lightweight discovery mechanisms for sensor networks and have been using software created by Cardiff to simulate P2P systems within the NS2 framework. The system is built on top of Agentj, which provides the ability to simulate real-world Java applications within NS2. The P2P software incorporated on top of this is P2PS, which is a lightweight peer-to-peer infrastructure which can be used to develop peer-to-peer style applications, Triana's main GAP P2P binding (www.p2psimplified.org).

Data-Mining Grid

The Data Mining Tools and Services for Grid Computing Environments (DataMiningGrid) Consortium is developing tools and services for deploying data mining applications on the grid. They aim to provide mechanisms that allow users to identify (locate), access, integrate and interface distributed data sources and data-mining programs in a flexible way. Triana is being used within this project as a workflow editor/manager to facilitate the composition, execution and management of data-mining workflows in grid computing environments.
