SHIWA and IGE projects are happy to announce the successful integration of Globus Toolkit 5 into the SHIWA Simulation Platform through its DCI Bridge component

The two projects, IGE and SHIWA, extended their collaborative efforts by signing a Memorandum of Understanding (MoU). The SHIWA project’s aim is to leverage existing workflow based solutions and enable cross-workflow and inter-workflow exploitation of Distributed Computing Infrastructures (DCIs) to help the collaboration of user communities that work on similar research field but use different workflow system.

The adaptation of the DCI Bridge Connector of SHIWA software to GT5 separated into two phases. In the first phase IGE analyzed the potential for migration of the GT2 and GT4 adaptors of the DCI Bridge to GT5, based on technical documentation and source code of the respective adaptors. In this phase IGE developed the GT5 adaptor (for file transfer and job submission) based on existing adaptors. In the second phase SHIWA developers integrated the GT5 plugin into the DCI Bridge, which will be followed by a testing phase using GT5 resources of the IGE Test bed.

The SSP (SHIWA Simulation Platform, http://ssp.shiwa-workflow.eu/) is a product of the SHIWA project and offers users production-level services supporting workflow interoperability. As part of the SHIWA Simulation Platform the SHIWA Repository facilitates publishing and sharing workflows, and the SHIWA Simulation Platform enables their actual enactment and execution in most of the DCIs (e.g. GT5) available in Europe. Workflows from different systems can be nested to compose new applications, using existing workflow components. The portal is based on WS-PGRADE/gUSE technologies.

Globus Toolkit/GT5: The open source Globus Toolkit is a fundamental enabling technology for the Grid, letting people to share computing power, databases, and other tools securely online across corporate, institutional, and geographic boundaries without sacrificing local autonomy. The toolkit includes software services and libraries for resource monitoring, discovery, and management, plus security and file management. GT5 is the last Globus grid type. Most components of GT5 are incremental updates (numerous bug fixes and new features) over their GT4 counter-parts (e.g. GridFTP, RLS, MyProxy, GSI-OpenSSH). Some components of GT4 are not included in GT5 (e.g. GT4 Java Core, WS-GRAM4, RFT), to be replaced by new software under development (e.g. Crux, Globus.org Service).

SHIWA - The SHIWA (SHaring Interoperable Workflows for large-scale scientific simulations on Available DCIs, http://www.shiwa-workflow.eu/) is a European project supported by the FP7 Capacities Programme under contract no. RI- 261585 and led by the LPDS (Laboratory of Parallel and Distributed Systems), MTA SZTAKI (Computer and Automation Research Institute, Hungarian Academy of Sciences). SHIWA is a collaboration of 8 consortium members and 5 subcontractors and focuses on the interoperability of many different European workflow systems and also provides access to a larger computational power with the interoperability solution between different Distributed Computing Infrastructures.

IGE - The Initiative for Globus in Europe (http://www.ige-project.eu) is a project providing European researchers with the tools to share computing power, databases, instruments, and other on-line tools. IGE is a member of the Globus Alliance, the collaboration that produces the Globus toolkit, an open source set of software components that address the most challenging problems in distributed resource sharing.
