3      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
4      ==============================      ==============================
5    
6    checkpoint34
7     o Modified exchange routines for correct reverse simulation.
8     o Added verification output to comply with bug fix in impldiff.F
9       as of c33 (exp2, natl_box).
10     o Corrected store directives in dynamics.F
11     o Corrected array boundaries in impldiff.F
12     o Corrected array dimensions in gmredi.
13       Added temporary scalars to avoid storage by TAMC (gmredi, kpp).
14     o Added mdsio_gl.F for ECCO purposes.
15    
16    checkpoint33
17     o Fixed bug in lower BC in impldiff.F
18     o Fixed confusion about units of forcing arrays in FFIELDS.h
19       namely Fu,Fv,Qnet,Qsw,EmPmR:
20       - Removed verification/natl_box/code/external_fields_scale.F
21         (did not differ from that in model/src)
22       - Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units
23         (see FFIELDS.h for description)
24       - Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F,
25         kpp_calc.F and kpp_transport_t.F
26       - Removed model/src/external_fields_scale.F and calls to it
27       - verification/natl_box uses flux data with "atmospheric" sign so
28         a special version of external_fields_load.F is used to
29         change the data as it's read in. This way, the arrays
30         have the right units and signs at all times tha a user could
31         possibly use them.
32     o Corrected genmake to delete a temporary file during configuration
33    
34    checkpoint32
35     o Scaling of forcing fields moved from external_forcing.F to
36       external_fields_scale.F, called directly after loading fields.
37     o Surface relaxation terms added to surface tendency fields in
38       extra subroutine.
39     o impldiff.F changed to avoid storing by TAMC of huge intermediate
40       fields.
41     o Changes in GMRedi to comply with packaging structure.
42     o Modifications and bug fixes in KPP package.
43     o Verification experiment for KPP added (verification/nat_box/)
44    
45    checkpoint31
46     o Packages interface brought in line with defined standard
47       -> new routines packages_...F
48       -> changes in initialise_fixed.F, initialise_varia.F
49       -> enables initialisation interface for ECCO package
50     o Rescaling of external forcing fields immediately after read
51       (removed from external_forcing.F)
52       -> new: surface_fields_scale.F
53       -> affects ini_foorcing.F, external_fields_load.F
54     o Computation of surface tendencies before tendency updates.
55       -> new: external_forcing_surf.F
56     o Change of variable names useGMRedi, useKPP, useECCO
57     o Further changes in dynamics.F, impldiff.F for TAMC
58     o Tested for experiments 0, 2, 4.
59       - not yet tested for GMRedi.
60       - not yet tested for KPP.
61    
62    checkpoint30
63     o Updates for OBCs
64     o New experiment for test OBCs (internal_wave)
65     o New output.txt in verification/exp4/results/
66     o Updates for KPP: calculation of viscosity corrected, new variables
67       kpp_dumpFreq and kpp_taveFreq
68     o CPP'd calls to system routines for TARGET_CRAY_VECTOR (P.H.)
69       and entry for T90 in genmake
70    
71    checkpoint29
72     o packaged KPP and GM/Redi
73    
74    checkpoint28
75     o Corrected initialization of hFacMin for difference vertical coordinates
76     o Modified calculation of partial cell thickness to more robust algorithm
77     o config_summary.F: replaced write_1D_... by write_0D_...
78       read_write.F: added subroutines write_0D_...
79     o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho:
80       included some initialisations required for TAMC.
81     o routine calc_isoslopes: modified sqrt computation to make it
82       differentiable for zero argument.
83     o routines dynamics, impldiff:
84       included store directives and tape key computations required for TAMC.
85     o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC
86    
87    checkpoint27
88     o fixed calc_isoslopes() to so that cancellation of terms in tensor
89       formulation works properly with variable resolution.
90     o restructured the calling tree between the_model_main() and dynamics()
91     o split initialise() into initialise_fixed() and initialise_varia()

93       in new routine ini_psurf()
94    
95    checkpoint26
96     o moved some #ifdef in optional routines to encompass everything
97       except the argument declarations. This was using up some memory.
98     o fixed macros like _ADT to work with both versions of Linux cpp
99     o cleaned up some unused and uninitialized variables
100       (helps when debugging with strict compile options)
101     o split up CPP_EEOPTIONS.h into options and macros
102       (macros are now in eesupp/inc/CPP_EEMACROS.h)
103     o patch for 2 processor JAM mode
104    
105    checkpoint25
106     o updates for OBCs and NH
107     o dramatically reduced memory usage
108     o added "JAM" routines for use on Artic network
109     o parameterization of convection by implicit vertical diffusion
110     o added a diagnostic of convective index
111     o moved call to calc_divg_hat() from dynamics() to solve_for_pressure()
112       (this is was partly for OBCs and NH but also in anticipation of
113        an explicit free-surface option)
114     o initial state input files for U and V
115    
116    checkpoint24
117     o Removed some spurious "REAL"s

147     o Split default parameters out of ini_parms.F into set_defaults.F.
148    
149    checkpoint18
150     o Further changes for optional code generation with
151       CPP - ugh!

165       syntax) and by g77 under Linux ( 72 character
166       limit ).
