1. SHIWA Simulation Platform (SSP) Gabor Terstyanszky, University of Westminster EGI Community Forum Munnich 27- 30 March 2012 SHIWA is supported by the FP7 Capacities Programme under contract No. RI-261585

2. SSP Objectives and Services Objectives: To create an environment which enables seamless execution of workflows of different workflow systems through workflow interoperability Services: To support the whole workflow lifecycle: editing, uploading, browsing downloading and executing workflows To provide coarse- and fine-grained workflow interoperability solution To offer Distributed Computing Infrastructure interoperability solution To provide desktop computer and portal interfaces to manage workflows Key actors: researchersworkflow engine developers workflow developers 2

3. 3 Workflow description abstract workflow plain text which describes the inputs and outputs and explains what the workflow does Workflow implementations concrete workflow It contains all implementation files or references to these files (via eg. URLs) and also holds other data/metadata necessary to run the workflow on its associated workflow engine. Workflow configurations It contains pre-defined input files and parameters or references to these files and parameters and other data/metadata of a workflow. Workflow engines It contains files and other data/metadata necessary to execute a workflow engine on a grid site or references to them SHIWA Data Structure

21. 21 Conclusions the simulation platform supports the whole lifecycle of workflows, i.e. creating, testing, uploading, browsing, downloading and running workflows users can use workflows of their own and of other workflow systems through the same user interface, i.e. they can re-cycle or share workflows created by other research teams or even other research communities workflow developers (or e-scientists) can create, run, upload workflows through the simulation platform researchers (astro physicists, earth scientists, bio scientists, etc.) can browse the workflow repository, select and run workflows through the simulation platform the simulation platform provides access to major European e- infrastructure, the European Grid Initiative (EGI) infrastructure which offers large pool of compute and storage resources
