Abstract

A methodology for distribution of a global climate model among computers connected by a wide area network is presented. The application consists of a model of the global atmosphere coupled to a model of the world ocean. It is demonstrated that a `metacomputer´ consisting of a CRAY Y-MP at the Jet Propulsion Laboratory and an Intel Delta at the California Institute of Technology connected by a highspeed (Gigabit per second) network can result in a superlinear speedup of execution of the atmospheric component of the global climate model code, despite the added overheads due to latency and communication delays
