Philosophy & Design
GENIE (Grid ENabled Integrated Earth system model) is comprised of a number of state-of-the-art components contributed by various authors. genie-main acts as the linchpin and couples together the other components. GENIE has a strict hierarchical design. Anything which is common or shared between components should reside in genie-main. Maintenance of this hierarchy promotes clarity for and significantly benefits the task of extending and improving the model over time.
<diagram>
Values are exchanged between coupled components by argument passing. They are declared in genie-main and passed to the relevant components through subroutine calls. This significantly aids traceability and debugging and avoids the pitfalls of 'spaghetti code', which may use common blocks as 'secret passages' between components--the source of many a debugging headache!
Default Settings
runtime_defaults.sh

Configuration Files
genie-main/configs
morph vanilla into flavours
Note compile-time and run-time settings
Compile
user.mak makefile.arc makefile (testing.mak)
calls sub-makefiles
Run the Model
user.sh

Source Code
- genie_control.f90
- flags to control the component coupling
- genie_global.f90
- any common variables (i.e. those used during coupling)
- constants, e.g. Pi
(** functions or subroutines which shold be common--put in a different module)
- genie.F
- the overall coupling logic and time loop: do this, then that, then the other, if, then, else.
argument passing.
