Initialise some scalars
with OBCS: use maskInC to cancel cg2d-matrix coeff at OB and also outside OB interior region (<- was missing in previous code); This can change cg2d Norm value and, as a consequence, can affect the results.
fix deep-atmosphere with topography (+ re-arrange do-loops)
add Christopher Wolfe's implemetation of the single reduction cg2d (d'Azevedo, Eijkhout, and Romine, 1999) with CPP-flag ALLOW_SRCG and runtime flag useSRCGSolver
use simple EXCH (overlap 1 and no Corner Exch): this reduces number of EXCH calls by 2 if using exch2).
change macros (EXCH & GLOBAL_SUM/MAX) sufix _R4/_R8 to _RS/_RL when applied to _RS/_RL variable
start to implement deep-atmosphere and/or anelastic formulation
clean-up multi-threaded problems (reported by debugger tcheck on ACES).
use "globalArea" (no need to re-compute it)
o first check-in for the "branch-genmake2" merge
o verification suite as run on shelley (gcc 3.2.2):

o included PACKAGES_CONFIG.h in all files where the ALLOW_${PKG_NAME}
defines are used
o added comments where IF ( use${PKG_NAME} ) statements will probably
be needed -- or need to be edited
Merging from c51
release1_p14 o Added interpolation routine pkg/exf/new_interp.F for on-the-fly interpolation. Enable with USE_EXF_INTERPOLATION and specify input grids in data.exf o Added direct pressure solver pkg/solver. See pkg/solver/README.directSolver for instructions.
merging c49 and e27
with cg2dTargetResWunit, define solver tolerance using deltaTmom (instead of deltaTfreesurf)
print to standard output enclosed between begin/end MASTER (and use "standardMessageUnit" instead of 6)
Added new parameter: deltaTfreesurf Previously, the free-surface equation was intergrated forward synchronously with the momentum equations. It is more consistent to use the tracer time-step. This increases the number of iterations required but strengthens the damping. We *SHOULD* make the default time-step equal to the tracer time-step. However, we don't for backward compatibility. At some point in the future we need to change the default behaviour. It turns out that the reason for the "reduced stability" encountered in large-scale runs seems to be related to excess variability in the free surface which in turn happens when the waves aren't damped. Using a longer time-step fixes this.
Changes encapsulated by checkpoint43a-release1mods and chkpt44d_post
on the main trunk.
These are:
o added missing EXCLUDE_MONITOR flags
o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
(incompatible typ in MIN/MAX expressions caused problems
on IBM SP3)
o in genmake added variable MAKEDEPEND
plus resetting for case SunOS
o added timer_stats.c routine for IBM SP3
o removed variables in dynamics
o real fresh water flux implemented with non-linear free-surface.
o few fix (mask in shap_s2, EmPmR in external_field_load,
USE_NATURAL_BCS in solve_for_P);
o add arguments myIter & myTime to S/R obcs_calc & solve_for_P
o merge of relevant stuff from the ecco-branch:
- genmake: removed $S64 overwrite for case SunOS
- pkg/exf: update and corrections for field swapping and obcs
- pkg/ecco: parameter lists for the_model_main, the_main_loop
harmonized between ECCO and MITgcm
- pkg/autodiff: added flow directives for obcs, mdsio_gl_slice
updated checkpointing_lev... lists for obcs
- model/src: minor changes in forward_step, plot_field
added directive for divided adjoint in the_main_loop
- pkg/mdsio: added mdsio_gl_slice
o check parameters & config (chkpt44a_pre,post)
o OBC and NonLin_FrSurf.
o fix bug in mom_vi_del2uv
o select when filters are applied ; add options to zonal_filter (data.zonfilt)
o gmredi: fix Pb in the adiabatic form ; add options (.e.g. Bolus advection)
o update AIM experiments (NCEP input files)
o improve and extend diagnostics (Monitor, TimeAve with NonLin-FrSurf)
o added some stuff for AD
These were merged with
cvs co -r release1 -P MITgcm
cd MITgcm
cvs update -kk
cvs update -j checkpoint43a-release1mods -j chkpt44d_post -d -P -kk
initialize to zero arrays in common blocs
Bringing comments up to data and formatting for document extraction.
compute Bo_surf(Po_ground,Tref) inside routine INI_LINEAR_PHISURF
Changed a write(0,...) to a write(*,...)
Merge from branch pre38: o essential mods for cubed sphere o debugged atmosphere, dynamcis + physics (aim) o new packages (mom_vecinv, mom_fluxform, ...)
define the solver tolerance in the appropriate Unit (cse of no RHS normalisation)
Key changes for linear shallow water equations on a cubic-spherical grid.
Ooops. Including wrong OPTIONS file.
Added option to use non-optimized (olx!=1) overlaps for internal arrays.
use gBaro instead of gravity to allow External mode reduced gravity test
change (*g) units of cg2d_x to have same units as all other potential Phi
separate the state variable "eta" from the 2D solver solution cg2d_x
implement a Crank-Nickelson barotropic time-stepping
Made sure each .F and .h file had the CVS keywords Header and Name at its start. Most had header but very few currently have Name, so lots of changes!
Merged changes from branch "branch-atmos-merge" into MAIN (checkpoint34) - substantial modifications to algorithm sequence (dynamics.F) - packaged OBCS, Shapiro filter, Zonal filter, Atmospheric Physics
Packaged OBCS (open boundary conditions) o source code now in pkg/obcs o controlled by namelist in data.obcs o includes Orlanski radiation condition (in same directory) o affects exp4 and internal_wave
Various updates for OBCs and Non-hydrostatic routines. o OBCs now fits into time-stepping properly o div.G has been moved to solve_for_pressure()
Added CPP macro ALLOW_OBCS to include/exclude open boundary code.
Changed number of arguments to GLOBAL_SUM and GLOBAL_MAX to two. Instigated by Ralf.
Modifications for non-hydrostatic ability + updates for open-boundaries.
Added IMPLICIT NONE in a lot of subroutines. Also corrected the recip_Rhonil bug: we didn't set it in ini_parms.F
Implementation of Open Boundaries:
o new source code: ini_obcs.F set_obcs.F apply_obcs1.F apply_obcs2.F
OBCS.h
o modified code at a few points, key changes are in
dynamcis.F the_model_main.F and ini_cg2d.F
o documentation in OBCS.h and doc/OpenBound.*
Changes to allow for atmospheric integration builds of the code
Changes to support - g77 compilation under Linux - LR(1) form of 64-bit is D or E for constants - Modified adjoint of exch with adjoint variables acuumulated.
Consistent isomorphism changes
Consistent isomorphism changes
Isomorphism consistency changes
Earlier, myNorm changed declaration from _RL to _RS. A call to _GLOBAL_MAX_R8 then causes bus errors on some platforms. We now call _GLOBAL_MAX_R4 to fix this. _GLOBAL_MAX_R4 is a macro that depend on REAL4_IS_SLOW.
Changes to make compatible with DEC F77 compiler
Fairly coplete 4 degree global intercomparison setup. Includes changes to make convective adjustment and hydrostatic pressure correct as well as IO for climatological datasets
Various corrections: o do_gterm_blocking..() is fixed to work with new time-stepping o CPP_OPTIONS.h now contains #define ALLOW_CD
Merge of GM Redi and spherical polar and inplicit diffusion and CD. Everything for a global run is now included, however, still some discrepancies with GM Redi.
Further memory saving macros for particular grids
Further memory saving macros for particular grids
Additional memory saving macros for special "grids"
Additional memory saving option changes
Changes to support "low" memory mode of operation - Small change to allow _RS -> REAL*4 to work - Added some macros for case where grid variations are a a subset of the general case. e.g. dx constnat or flat bottom
Turned 2d conjugate gradient incomplete-factorisation preconditioner on.
Added changes to support implicit free-surface. - included gBaro a "barotropic" gravity that can be set differently to the g.rhoprime gravity. - discovered and fixed coding error in dynamics loop. Per tile temporaries that needed correct initial values were not being reset for each tile.
Added active preconditioner
Improvements to I/O and feedback info.
Further $Id to $Header conversions
Imported working release
