NOAA GFDL's Flexible Modeling System (FMS)
Entry ID: GFDL_FMS
Abstract: FMS is a software framework for supporting the efficient development,
construction, execution, and scientific interpretation of atmospheric, oceanic,
and climate system models. FMS comprises the following:
1. A software infrastructure for constructing and running atmospheric, oceanic,
and climate system models. This infrastructure includes software to handle
parallelization, input and output, ... data exchange between various model grids,
orchestration of the time stepping, makefiles, and simple sample run scripts.
This infrastructure should largely insulate FMS users from machine-specific
2. A standardization of the interfaces between various component models.
3. Software for standardizing, coordinating, and improving diagnostic
calculations of FMS-based models, and input data preparation for such models.
Common preprocessing and post-processing software are included to the extent
that the needed functionality cannot be adequately provided by available
4. Contributed component models that are subjected to a rigorous software
quality review and improvement process. The development and initial testing of
these component models is largely a scientific question, and would not fall
under FMS. The quality review and improvement process includes consideration of
(A) compliance with FMS interface and documentation standards to ensure
portability and inter-operability, (B) understandability (clarity and
consistency of documentation, comments, interfaces, and code), and (C) general
computational efficiency without algorithmic changes.
5. A standardized technique for version control and dissemination of the
software and documentation.
FMS does not include the determination of model configurations, parameter
settings, or the choice amongst various options. These decisions require
scientific research. Similarly, the development of new component models is a
scientific concern that is outside of the direct purview of FMS. Nonetheless,
infrastructural changes to nable such developments are within the scope of FMS.
The collaborative software review process of contributed models is therefore an
essential facet of FMS.
