There are already several well established grid and cloud infrastructures in Europe. The next issue is how to exploit these infrastructures, how to port and develop application for these infrastructures and how to extend their user communities. The main goal of this summer school is to give answers for these questions and to promote best practice examples for potential application developers and users of e-science infrastructures.

Three current FP7 projects organize this summer school to show various aspects of user support for the European grid and cloud infrastructures. The SCI-BUS project will train application developers how to develop workflows and parameter sweep applications for distributed computing infrastructures (DCIs) based on the WS-PGRADE workflow concept and the gUSE high-level user support environment that enables transparent access to various DCIs like grids (ARC, gLite, Globus, UNICORE), clouds (OpenNebula, Openstack, Amazon, Google Application Engine), desktop grids (BOINC), clusters (PBS, LSF) and supercomputers. SCI-BUS will also show how to customize the generic WS-PGRADE/gUSE gateway according to the needs of various user communities and create application-specific science gateways for these communities.

The SHIWA project will explain how those user communities who are engaged with one of the major workflow systems (ASKALON, Galaxy, GWES, Kepler, MOTEUR, Pegasus, Taverna, Triana, WS-PGRADE) can explore the various DCIs mentioned above via the services of gUSE. SHIWA enables sharing workflows between different user communities and combining different type of workflows to build meta-workflows via the SHIWA Workflow repository, SHIWA Portal and SHIWA desktop technologies. The SHIWA portal is also based on the WS-PGRADE/gUSE gateway so it is a good case study how to customize the WS-PGRADE/gUSE gateway for specific community needs.

The EDGI project enables the extension of grids (ARC, gLite, UNICORE) with institutional and volunteers desktop grids giving the possibility to significantly increase the available resources for these grids in a cost-effective way. The EDGI project will explain the possible ways how this extension can be made and also explains how to port applications to this extended and integrated DCI. It will be also shown how the WS-PGRADE/gUSE gateway can be used to run workflows with parametric jobs in a transparent way on such an integrated grid/desktop grid DCI. The SpeQuloS system developed in EDGI enables the transparent extension of the integrated grid/desktop DCIs with clouds where QoS requirements are needed for the users. SpeQuloS will be also explained during the summer school and potential users will be trained how to use it.

Although the summer school is organized by the three above mentioned projects its subject is not restricted for showing the technologies developed by these projects. Related projects will be invited to explain how their technologies are related with the technologies mentioned above and how the potential users can exploit all these technologies together. We plan to invite wf4ever and MAPPER to talk on their workflow related results, StratusLab and Venus-C to present their cloud solutions, DEGISCO to explain how the integrated grid/desktop grid DCIs are used outside the EU, IGE to explain their Globus technology, SEE-HP to show how they adapted the WS-PGRADE/gUSE gateway for supercomputers and for their user communities, agINFRA to present their plans to provide science gateway for agriculture, EGI-Inspire and the Hungarian NGI to explain their support for DCI user communities.

To whom do we recommend the summer school?
  • PhD students and technical staff members who are interested in learning the grid middleware, desktop grid and cloud technologies.
  • Application developers and workflow developers who develop distributed applications based on these DCI technologies and infrastructures.
  • Science gateway developers who want to provide gateway access to these DCIs for their user communities.
  • System administrators who would like to run DCI services and science gateway services.
  • Staff members of companies who would like to establish company level DCI (clouds, grids, desktop grids) and utilize this DCI or other commercial clouds via a high-level gateway service.


Budapest, one of the most beautiful historical capitals in Europe, situated on the banks of the Danube, will host the summer school. The architectural beauty with its monuments from neo-classic through baroque to eclectic art nouveau is prevalent in the city. Budapest is also world famous for its artistic abundance of concerts, operas, recitals, galas and exhibitions. The warm hospitality of people, excellent food and wine reliable and frequent public transportation, vivid cultural life, rich museums attract millions of visitors every year. Visitor friendly visa policy, value-for-the-price services and goods, and pleasant climate make Hungary one of the most popular meeting venues worldwide.
