Viridian Climate Modelling

Postby John Sterman » Thu Nov 11, 1999 2:06 pm

Folks, The following message, forwarded by Alan AtKisson to the Balaton Group (founded by Dana and Dennis Meadows, a group of folks committed to creating a sustainable world), describes a terrific idea for distributed modeling. The same concept is being used to factor large numbers for codebreaking, for processing SETI data, and for other tasks. Why not use it to speed the analysis of large simulations of all types, not only climate models.
