Instructions for computing Green functions with constant surface
forcing for Nir Krakauer's paper on Columbia.
Assume that surface forcing files are available in MITgcm/../iter69
===================================================================

1 ===> get MITgcm code from cvs repository

 cvs co -r checkpoint51n_branch MITgcm_code
 cvs co -r checkpoint51n_branch MITgcm/verification/testreport
 cvs co -r checkpoint51n_branch MITgcm/verification/global_with_exf

2 ===> put MITgcm_contrib/ocean_inversion_project in MITgcm directory

 cd MITgcm
 cvs co -d ocean_inversion_project MITgcm_contrib/ocean_inversion_project

3 ===> compile and link

 mkdir bin exe93 exe99
 cd bin
 \rm *
 \cp ../ocean_inversion_project/code_ecco1x1/* .
 \mv ptracers_forcing_surf.F_gasflux ptracers_forcing_surf.F
 \mv ptracers_init.F_gasflux ptracers_init.F
 \mv PTRACERS.h_gasflux PTRACERS.h
 \cp SIZE.h.36 SIZE.h
 \rm PTRACERS_OPTIONS.h* ptracers_read_takahashi.F
 ../tools/genmake2 -of linux_ia64_ifort+mpi_altix_nas
 make depend
 make -j

4 ===> run integrations starting in 1993 (exe93) and 1999 (exe99)

 cd ../exe93
 \cp ../bin/mitgcmuv .
 \cp ../ocean_inversion_project/input_ecco1x1/* .
 \ln -sf ../../iter69/* .
 \ln -sf ../ocean_inversion_project/region_mask/30reg_regionmask.bin .
 qsub job_gasflux93

 cd ../exe99
 \cp ../bin/mitgcmuv .
 \cp ../ocean_inversion_project/input_ecco1x1/* .
 \ln -sf ../../iter69/* .
 \ln -sf ../ocean_inversion_project/region_mask/30reg_regionmask.bin .
 qsub job_gasflux99
