Abstract :
Diagrammatic description of satellite imagery processing has been developed in the MedioGrid system through the gProcess toolset. The processing workflow supports a flexible exploration of different algorithms and computing configuration over the grid. This paper concerns with experimental evaluation of the optimal mapping of the logical workflow onto the physical level. The execution time is evaluated for horizontal and vertical grouping techniques of the operational nodes.
