Configuration in PRISM : Constraints

1
Configuration in PRISM Constraints

• The system must to accommodate any ESCM model
• No changes of the model code required
• Exception
• implementation of PRISM software (PSMILe)
• Source code reorganisation to standard (e.g.
  flat tree to enable use of (simple) tools)
• New namelist parameters (e.g. of processors)
• Not allowed
• Editing of source code before each compilation
• Duplicate file names
• gt1 F90 module per file
• File name ! F90 module name
• All constellations realised without editing of
  source code or scripts

2
Configuration in PRISM GUI

• All configuring described can be done through the
  GUI
• Proposed for GUIs in PRISM
• Separate Configuration and SMS GUI

3
Configuration in PRISM Methods

• Changing aspects of an experiment without
  editing
• by user action
• Through a GUI
• Through command line parameters of shell scripts
  (clp)
• (if no default)
• Configuration files (cf)
• by automatic action
• GNU auto...
• Recognition of platform
• of
• Compile scripts / Makefiles gt Models
• Run etc. scripts / Namelists gt Experiments

4
Configuration in PRISM Scripts

• All configuration modifies scripts
• Compile scripts gt Component models
• gt Platforms
• gt Compiler options
• gt Launching method (MPI1,2)
• gt OASIS3 or OASIS4 (to come)
• gt Coupled constellations
• gt Model internal configuration
  (param. etc)
• Run scripts gt Platforms
• gt Coupled constellation
• gt Experiment characteristics
• gt Namelists

5
Configuration in PRISM Experiments

• Run scripts
• Coupled constellation (clp)
• Name of coupled model/constellation
• Platforms (clp or automatic)
• Host name
• Experiment characteristics
• Experiment ID (clp)(path names, executable
  versions)
• file system (cf)
• Resolution of models (cf)
• w/o vis/arch/data proc (cf)
• Length of exp. / runs (cf)
• Exchange frq. (cf)
• etc. (cf)

6
Configuration in PRISM Experiments

• Namelist values are set by export of environment
  parameters from cf
• (ASCII input / Namelists / namcouple / XML)
• Reformatted start and stop date
• Model time step
• Exchange frequency
• processors
• etc.
• Other model namelist values have to be set by
  editing

Configuration in PRISM Models

• Compile scripts
• gt Coupled constellations (clp)
• gt Launching method (clp)
• gt Platforms (clp automatic)
• gt Version ID (clp)
• gt Compiler options (to come)
• gt OASIS3 or OASIS4 (to come)
• gt Model internal configuration
  (parameterisation of physics etc.
  by editing)
