In our demonstration we present Trident, a scientific workflow workbench built on top of a commercial workflow system to leverage existing functionality to the extent possible. Trident is being developed in collaboration with the scientific computing community for use in a number of ongoing e-Science projects that make use of scientific workflows, in particular the Pan-STARRS sky survey project and the Ocean Observatory Initiative. In our demonstration of Trident we will illustrate the ability to utilize both local and cloud resources for storage and execution, as well as services such as provenance, monitoring, logging, and scheduling workflows over clusters. Our goal is to release Trident in early 2009 as an open source accelerator for others to use for e-Science projects and to continue extending with support for new workflow features and services.
