Abstract
The computational demands in the field of weather prediction and clima te studies are very large, but it is difficult to buy many supercomput ers in the country because of financial constraints. A global weather model has been modified for its implementation on 16 processors of par allel processing system (PPS) developed by C-DOT, Bangalore. It is fou nd that the performance of the model on PPS is about 8 times slower th an on CRAY-XMP 216 with one CPU in the case of 10-day integration.
