Scientific workflow

Scientific Workflow

  • These are networks of analytical steps that may involve, e.g., Database access and querying steps, data analysis and mining steps, and many other steps including computationally intensive jobs on high performance cluster computers.

Scientific workflow1

Scientific Workflow

  • Workflow:“glue” heterogeneous data from multiple resources in efficient ways

  • Workflow management system (WMS)A Software that supports workflow modeling and execution

Advantages

Advantages

  • Automate scientific data analysis, simulation, and visualization

  • Conceptual-level design hide distributed computing details

  • Intuitive to use

  • Collaboration

Mainstream swfs

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 swfs1

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 swfs2

Mainstream SWFs

  • Tavernahttp://www.mygrid.org.uk/tools/taverna/1. is an open-source, Grid workflow management system2. aimed at facilitating standard scientific procedures inthe eScience domain.


Mainstream swfs3

Mainstream SWFs

  • Pegasushttp://pegasus.isi.edu1. Pegasus map the high-level workflow descriptions onto distributed infrastructures2. Pegasus is used map complex, large-scale scientific workflows with thousands of tasks (data-intensive, compute-intensive)onto the Grid.

OSGi

  • OSGi:http://www.osgi.org/Main/HomePageOSGi(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.
