Perspective of an SMEs for the use Grid Computing v v v Local SMEs have serious technological limitations due to lack of access to state of the computational systems Often the need to stay on the edge of nowadays competitive market imposes the use of design and simulation methods of very high computational cost, even for small production series Grid Computing equipment is too costly for SME budgets Scientific/technical training for the use of Computational Grids is still limited There is a limited connection between SMEs and users of computational grids (Universities, Research Centers)

Perspective of an SMEs for the use Grid Computing v v A structured cooperation between primary actors in the development of the Computational Grid infrastructure could boost its use on the part of SMEs If SME can rely on a steady support in the use of Computational Grids, new business development in High-Tech markets will be possible Training facilities for the transfer to SME engineers of updated information on the potential of Grid Computing would be essential to help in defining possible uses of the grid facilities The use of shared computing facilities poses information security issues which need to be addressed
