✦ Synopsis

This paper describes recent developments made to the open source general purpose CFD code Code_ Saturne that attempt to address challenges associated with computing at the Petascale. These new features include parallel improved linear solver techniques, parallel I/O methodologies and partitioning tools. The impact of these new features on parallel performance has been analysed for a range of prototype Petascale computing systems as part of the PRACE pan-European initiative.

Three different optimization procedures, which are expected to improve the performance of large solar thermal systems, are described in this paper. The first procedure concerns the planning phase of the system. The second one considers its operation and should be carried out after about one year of

The distance transform (DT) is an image computation tool which can be used to extract the information about the shape and the position of the foreground pixels relative to each other. It converts a binary image into a grey-level image, where each pixel has a value corresponding to the distance to th
