Abstract :
We discuss the parallelization and distribution of a workflow based application. We present experimental results and discuss lessons learned. The experimentation is based on a scientific application case study - sequential simulation applied to geostatistics. As a result we identify a list of issues not well supported in the most referenced scientific workflows tools and environments namely Kepler, and outline relevant research directions.
