What is the MARS environment

3 Directories

• MARS environment is composed by 3 directories :

  • MARS_CONFIG : for compilation and code modification by the user
  • COMPILE_MARS : where the compile code is (The user doesn’t need to go in this directory and he must not modify files otherwise user’s changes might be lost)
  • RUN_MARS : for run simulations by the user, and where there are input and output files

3 scripts

• mkconfdir : create the directories of a configuration (MARS environnement : List of useful commands)
• makefile : manage the configuration (choice of rank, test case, previous configurations), and compile the code by calling Makefile.linux or Makefile.datarmor
• Makefile.linux or Makefile.datarmor : MARS compilation with CPP keys

Reference code

• The originial code (reference code) is placed in the Reference directory $HOMEMARS/..

• which contains :

  • MARS sources,
  • Scripts of MARS environment,
  • Makefile for the compilation,
  • Input files as namelists and ‘*’.dat (river.dat, outflow.dat…)
  • Documentation : manuals, faq
  • Module example (fortran)
  • Libraries (netcdf, io_netcdf)
  • Code rules

• The directory $HOMEMARS is defined in the user file : .cshrc
