Hi Ptolemy developers, I am a member of the myGrid workflow project in the United Kingdom, trying to hook up with people with in depth knowledge of Ptolemy's Directors during or after the Ptolemy workshop on May 12th.
myGrid has developed a set of components to construct workflows in bioinformatics and is linked to Kepler through the LinkUp initiative (http://www.mygrid.org.uk/linkup/). Some of the capabilities of the Kepler and myGrid workflows are highly complementary, which has recently spawned activity to interoperate the two environments. As part of this, I'm coming over to the Ptolemy workshop to see how the Ptolemy concepts relate to a set of standard patterns for control flow[1], data[2] and resources[3] in workflow systems. These patterns were originally developed to compare commercial workflow software but seem relevant for scientific workflow systems, too. The patterns do not address how combinations of patterns result into distributed execution models, and how such models can be combined, a feature offered by Ptolemy. I am looking for people who would be interested to sit down with me and go over my mappings between the two. I will be in Berkeley 12-13 May, and in San Diego the beginning of the week after. If you're interested to work with us on this, please get in touch.
