CoreGrid Summer School, Budapest, i2g Offer Support for external developers and users applications The Interactive European Grid project helps application developers in adapting their applications to work in a Grid environment as well as in parallelization of these applications. If you would like us to consider running your application in the int.eu.grid infrastructure or creating a new VO, please contact: Isabel Campos IFCA-CSIC*, Santander, Spain iscampos AT ifca.unican.es Grid infrastructure The Project helps to integrate new clusters to the int.eu.grid infrastructure as well as to establish agreements between research communities and infrastructure providers. If you would like to join the int.eu.grid infrastructure with your cluster, please contact: Project support team i2g.support AT lip.pt Education Tutorials: for Grid beginners, Grid site administrators, application developers; some tutorials on MPI and other Grid specific. If you would like to join the tutorial organized at our site or to organize our tutorial at your facilities, please contact: Celso Martínez Rivero IFCA-CSIC, Santander, Spain mrivero AT ifca.unican.es Seminars for groups of interested people or consultancy. If you need a consultancy or you are interested in taking part in a seminar on Grid technology, please contact: Project Office Santander, Spain inteugrid-office AT ifca.unican.es specifying the subject, product or problem. Disseminative materials General information about the Project – brochures, posters, etc. General int.eu.grid presentation. If you are interested in receiving them, please contact: Robert Pajak CYFRONET*, Kraków, Poland r.pajak AT cyfronet.krakow.pl
