1. FUJIN: a parallel framework for meteorological models
FUJIN is a framework for meteorological simulation models. Using this framework, existing models are easily parallelized, nested and coupled with minimal effort and minimal time.
Features of the FUJIN
modular and layered structure
information hiding technique provides simple interface to the users
paralleled by MPI
parallel package
data definition
coupler
model
Any process of existing models are easily add to FUJIN’s model
Existing model is easily plugged in the FUJIN and easily parallelized, nested and coupled.
Functions of the FUJIN
parallel computing
2 dimensional domain decomposition
variable halo width
domain nesting
no limitation on nesting depth
one way nesting
coupling
multi-model coupling
atmosphere
data exchange
ocean
sea ice
task control
land
Structure of the FUJIN
FUJIN is constructed with 3 layers and a atmospheric model.
　Parallel package is basic parallel library package using MPI.
　Data definition layer defines the data structure supports　 　　parallelism and domain nesting.
　Coupler controls each task and manages data exchange.
　Model is based on CReSS and fully rewritten with Fortran 90.
