SHIWA Technology hackathon at EGI Community Forum 2014


The hackathon will be held at the EGI Community Forum 2014 on 21 May 2014 at 4 pm. Duration: 90 minutes


The ER-flow project is building a European Research Community that investigates interoperability of scientific data in the context of scientific workflows. The project disseminates the FP7 SHIWA project's achievements, particularly the Coarse-Grained workflow interoperability solution (CGI) using the SHIWA Simulation Platform. The project includes four major research communities, Astrophysics, Computational Chemistry, Heliophysics and Biomedicine, which already successfully run their experiments using SHIWA Simulation Platform and have their scientific workflows exported to the dedicated SHIWA Workflow Repository for sharing. The platform supports various Distributed Computing Infrastructures (DCIs) such as: clouds (Amazon and Openstack) as well as service grids  (gLite, Globus and UNICORE) . The interoperability solution includes various workflow systems such as: Askalon, Galaxy, Kepler, Moteur, Pegasus, PGRADE, ProActive, Taverna, Triana and WS-PGRADE. By using the SHIWA platform the research communities have freedom to choose from a large variety of workflow management systems, infrastructures or middleware to implement their Virtual Research Environments.

The workshop will be structured as follows

  1. Introduction (5')
  2. Tutorial on creating and executing workflows (30')
  3. Applying workflow technology to scientific problems (group exercise) (30')
  4. Solution examples (20')
  5. Closing remarks (5')

After a brief introduction to the SHIWA platform and the WS-PGRADE workflow management system, the participants will be invited to learn how to create, configure, execute, monitor and store simple workflows. The participants will then work in groups to discuss how to adopt workflow technology in their own scientific problem. The instructors, will lead the discussion and, as much as possible, illustrate the solutions using examples of workflows already in the SHIWA repository. Depending on time, they will also create simple illustrations using the SHIWA portal. Wider impact and conclusions Expected Goals: the participants will learn in practice how to design, create and execute scientific workflows to address their own research questions using WS-PGRADE workflow system provided within the SHIWA Simulation Platform. Also participants will get familiar with solution from the demonstration, which addresses interoperability between the different workflow systems, as well as supports sharing of scientific workflows through SHIWA Workflow Repository.
