Computer Benchmarking

We port different numerical weather/climate model codes into vector and parallel computers such as the Cray J90, the Cray T3E, the SGI Origin 2000, and a network of PCs.

In the process of porting, we also report the parallel performance of each code on the above computers.

We have ported and benchmarked the Community Climate Model CCM3 on the Cray J90 and the Cray T3E, the Mesoscale Model MM5 on the Cray J90, the Cray T3E and a network of PCs, and the regional atmospheric model Eta on the Cray T3E and a network of PCs.

It is better to stay quiet than talking too much and making false promises.
