CoDIMS-G: a data and program integration service for the grid

Grid services provide an important abstract layer on top of heterogeneous components (hardware and software) that take part into a Grid environment. In this scenario, applications, like scientific visualization, require access to data of non-conventional data types, like fluid path geometry, and the evaluation of special user programs on these data. In order to support such applications we are developing CoDIMS-G, which is a data and program integration service for the Grid. CoDIMS-G provides users transparent access to data and programs distributed on the Grid, as well as dynamic resource allocation and management. We conceived a new node scheduling algorithm and designed an adaptive distributed query engine for the grid environment.
