...
- Generates a Fortran/CPP wrapper, which intermediates between Kepler actor and user code in terms of:
- reading/writing of in/out physical data (IDS)
- passing arguments of standard types to/from the actor
- Creates a Kepler actor that:
- calls a user code
- provides error handling
- calls debugger (if run in "debug" mode)
- calls batch submission commands for MPI based actors

Below you can find explanation of FC2K arguments tab.
|
| Fig. 4. "Arguments" tab |
|---|
- Type - Defines a type of an argument. It is possible to choose either IDS based type (e.g. equilibrium, topinfo, etc.) or primitive type (e.g. int, long, double, char)
- Single slice - Determines if IDS is passed as single slice or an array. (This setting is valid for IDS types only
)- if turned ON - Only one slice is passed. An actor will get an additional port to define a time.
- if turned OFF - All IDSes for given shot run is passed.
- Is array - Determines if a primitive type is passed as a scalar or an array
- if turned ON - An argument is passed as an array. It requires definition of array size (dynamic array are not supported)
- if turned OFF - An argument is passed as a scalar.
- if turned ON - An argument is passed as an array. It requires definition of array size (dynamic array are not supported)
- Array size - Defines the size of an array of primitive types (-1 in case of arrays of dynamic size)
- Input - Defines argument as an input
- Output - Defines argument as an output
- Label - User defined name of an argument (and actor port)
| Warning |
|---|
Restrictions concerning type and order of arguments Arguments specified in this tab must match a type and order of arguments of the routine/function. |
|
| Fig. 5. An example of subroutine arguments |
|---|
...
- equilibrium - an input parameter - one IDS (slice)
- amns_data - an input parameter - all amns_data IDS slices stored in given shot/run
- integer - an input parameter - a scalar
- double - an input parameter - an array of size 10
- edge_source - an in/out parameter - single slice of "edge_source" IDS
- waves - an output parameter - all slices of "waves" IDS
...
Code specific parameters are all parameters which are specific to the code (like switches, scaling parameters, and parameters for built-in analytical models) as well as parameters to explicitly overrule fields in the ITM data IMAS data structures.

A "Main library" field allows to define a path to library containing user subroutine/function.

"Custom libraries" are non-standard static libraries required for building the user code.

"System libraries" are system libraries handled by pkg-config mechanism and required for building the user code.

- add library from the list,
- remove library

A user, using this tab, selects programming language of codes provided, compiler used to built library and type of code execution (sequential or parallel)
|
| Fig. 12. "Settings" tab - code description |
|---|
- Programming languange:
- Type - Defines programming language of user codes. It could be set to:
- Fortran
- _C/C++
- Compiler - Defines compiler being used. Possible values:
- ifort, gfortran
- gcc, g++
- Type - Defines programming language of user codes. It could be set to:
- Computation:
- Parallel MPI - If turned ON uses MPI compilers (mpiifort for ifort, mpif90 for gfortran, mpigxx for C)
- OPENMP - Defined if usage of OpenMP directives is turned ON/OFF
- Batch - If turned ON, submits a user code to jobs queue (combined with Parallel MPI or OPENMP switch runs user code as parallel job)
- Additional features:
- Calls init method - If user function needs any pre-initialization, an additional function will be called.
- Returns diagnostic info - adds output diagnostic information

9 Sandbox
"Sandbox" - a directory, in which actor will be run. Before execution of user codes wrapped by FC2K generated actor, directory will be changed to "sandbox", and after actor finishes, current directory will be switched back to previous value. The name (path) of "sandbox" directory will be created automatically or specified by user in actor configuration dialog.
...
- actor uses sandbox
- a sandbox parameters shown in actor configuration dialog (see next paragraph)
