Abstract
We discuss the question, whether the parallel IFS weather prediction m odel of the ECMWF can efficiently run on a cluster of supercomputers. In a joint project with Gray Research, we studied C90 systems which we re connected by Hippi channels. The analysis shows that indeed a very high efficiency can be achieved provided the right parallelisation, cl uster partitioning, and mapping approach is applied.
