i2g Offer

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 CamposIFCA-CSIC*, Santander, Spain

email: iscampos AT ifca.unican.es

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 RiveroIFCA-CSIC, Santander, Spain

email:mrivero AT ifca.unican.es

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

email: i2g.support AT lip.pt

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

email: inteugrid-office AT ifca.unican.es

specifying the subject, product or problem.
