Legacy code support for service-oriented production grids

Abstract

Current production Grid systems are just before a transition period when they are moving form resource-oriented to service-oriented Grid middleware. However, only changing the underlying Grid middleware and the basic services will prevent end-users to fully utilise the Grid. Users also require higher level services that make access the Grid easier. This paper presents how a higher level service like the GEMLCA legacy code solution can be connected to service-oriented production Grids. It identifies dynamic account management and automated resource testing as two main challenges to be solved and offers solutions for these challenges.
