Mainstream SWFs

Keplerhttps://kepler-project.org/

1. is a java-based application that is maintained for the Windows, and Linux operating systems.

3. is built upon the Ptolemy II system.

4. focus on actor-oriented design.Actors are re-usable independent blocks. such as web services.

Mainstream SWFs

Trianahttp://www.trianacode.org/

1. Triana is Data flow based.

2. simplify define, analyse, manage, execute and monitor workflows.

3. Components basedsimplify the applicationdesign process and to speed up application development

Mainstream SWFs

Tavernahttp://www.mygrid.org.uk/tools/taverna/

1. is an open-source, Grid workflow management system

2. aimed at facilitating standard scientific procedures inthe eScience domain.

Mainstream SWFs

Pegasushttp://pegasus.isi.edu

1. Pegasus map the high-level workflow descriptions onto distributed infrastructures

2. Pegasus is used map complex, large-scale scientific workflows with thousands of tasks (data-intensive, compute-intensive)onto the Grid.

OSGi:http://www.osgi.org/Main/HomePage

OSGi(open service gateway initiative) technology is Universal Middleware. OSGi technology provides a service-oriented, component-based environment for developers These capabilities greatly increase the value of a wide range of computers and devices that use the Java platform.
