B component set

The shorthand name for the combination of all active components of CCSM: ocean, atmosphere, land, and ice exchanging information via a coupler.

CCSM

The Community Climate System Model is a fully-coupled, global climate model that provides state-of-the-art computer simulations of the Earth's past, present, and future climate states.

CICE

The Los Alamos sea ice model

CSIM

The CCSM Community Sea Ice Model

CSIM4

Version 4 of the CCSM Community Sea Ice Model that was released in May 2002 with CCSM2.0.

CSIM5

Version 5 of the CCSM Community Sea Ice Model that was released in June 2004 with CCSM3.0.

CVS

The Concurrent Versions System used to record the history of source code.

CVS branch

A line of development separate from the main trunk.

CVS main trunk

The main line of development on the CVS source tree.

Los Alamos National Laboratory

load balancing

The distribution of processing and communications activity between components to minimize the resources used and the time spent waiting by any single component.

PCWG

The Polar Climate Working Group is a team of scientists who develop and improve the sea ice component of CCSM, and who use the ice model alone or fully coupled in CCSM for studies of polar climate.

ProTeX

A perl script that allows for automatic generation of Latex compatible documentation of source code, without a considerable effort beyond the documentation of the code itself.
