Abstract

The multiscale three dimensional Chemistry and Transport Model (CTM) package Chimere has been ported onto the segment of the European Grid Initiative platform available to the Virtual Organization COMPCHEM as part of the MPI parallelization activities of the European project EGI-Inspire. The model adopted by the package, its structure, the parallel restructuring made to execute it on EGI and an analysis of some of the main factors affecting its parallel performances are illustrated and discussed.
