Scientific Workflows Survey

Recent changes:

What is it?

Intention of this page is to be community resource where anybody interested in Scientific Workflows can find pointers to current projects and to background information about workflows.

For more background information see Workflow Management Research Group and in particular materials from GGF10 Workflows in Grids workshop (2004/3/9) that provide an interesting snapshot of current activities, see: http://www.extreme.indiana.edu/groc/ggf10-ww/index.html

We have gathered here pointers and short descriptions of Scientific Workflow projects. We appreciate if you send to us pointers to new projects (and any corrections).

We try to to keep this list as complete and current as possible.

Thanks!

P.S. European projects K-Wf Grid and CoreGRID I established a "Grid Workflow Forum" at http://www.gridworkflow.org/ as an open forum for information exchange and discussions about scientific and commercial approaches in the domain of Grid Workflows.

P.S.2 Use ATOM feed to track updates.

This page is always under development and updated frequently!
