SHaring Interoperable Workflows for large-scale scientific simulations on Available DCIs
1 Jul 2010– 30 Sep 2012

The SHIWA project's main goal is to leverage existing workflow based solutions and enable cross-workflow and inter-workflow exploitation of DCIs by applying both coarse- and fine-grained strategies.

The coarse-grained (CG) approach enables to combine workflows written in different workflow languages in order to reuse existing reuse and combine existing workflow applications written in various workflow languages. The CG approach treats existing workflows as black box systems that can be incorporated into other workflow applications as workflow nodes.

The fine-grained approach addresses language interoperability by defining an intermediate representation to be used for translation of workflows across various systems (ASKALON, Pegasus, P-Grade, MOTEUR, Triana).

SHIWA develops, deploys and operates the SHIWA Simulation Platform to offer users production-level services supporting workflow interoperability following both approaches. As part of the SHIWA Simulation Platform the SHIWA Repository facilitates publishing and sharing workflows, and the SHIWA Portal enables their actual enactment. Use cases targeting various scientific domains will serve to drive and evaluate this platform from a user's perspective.
