This is how you re-compile the code.

MPI to single

• Go to libs and edit configure-libs (change MARCH from mpi to single).
• $ make clean, $ configure-libs, and $ make.
• Go to rsm or gsm and edit configure-model (change MARCH from mpi to single and NPES to 1).
• $ make clean, $configure-model, and $ make
• Go to gruns or rruns and $ configure-scr your_run_script_name

Change number of processors

• You do not need to changes libs directory. libs directory is independent of resolution and number of processors.
• Go to rsm or gsm and edit configure-model (change NPES).
• $ make clean, $configure-model, and $ make.
• Go to gruns or rruns and $ configure-scr your_run_script name
