Parallel Community Climate Model for Scalable Message
Passing Systems

abstract

PCCM2.1 is a parallel version of the NCAR Community Climate
Model, CCM2, implemented for MIMD massively parallel computers using
a message-passing programming paradigm.

environment

The parallel implementation was developed for the
Intel Paragon with 1024 processors and IBM SP2 with 128 processors.
The code can be easily prted to other multiprocessors supporting
a message-passing programming paradigm, or run on machines distributed
across a network with PVM.
