ROOM:399

ABSTRACT:
Workflows are now commonly used to create scientific simulations and investigate scientific problems, and visualise scientific data. There are a range of workflow engines and workflow languages and engines, such as Kepler (which is based on the Ptolemy II system), Pegasus, and the Taverna Workbench. There are a number of groups working on extending workflow technologies into the high performance computing domain (i.e. Grid, Cloud, and Parallel computing), including the EUFORIA project which has worked on extensions to Kepler to enable the launching of parallel and Grid computing jobs as well as visualising large and 4D datasets. Furthermore, the Pegasus workflow engine (Pegasus-WMS) includes functionality to utilise Grid, Cluster, and Cloud resources. There is also a lot of work being undertaken to integrate existing simulation codes into workflows, rather than just developing new simulations or codes. There is a massive body of existing scientific codes, with many of them the results of tens of years of development work, which cannot feasibly be redeveloped as a workflow but could benefit from the visualisation, data tools, computational resources, etc... that workflows can offer. This BoF is focussed on providing a forum for groups who are working to create and use workflows on high performance computing and are integrating (or interested in integrating) existing simulation codes into workflows. There will be presentations from a number of groups who are developing workflow extension for existing codes or high performance environments, and those who are using such technologies for scientific simulations. It will also allow interested parties to provide feedback, ask questions, and gain an understanding of what workflow technologies can help with.
