4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/seaice: simplify the use of CPP flags in JFNK-related files
8        (compile when SEAICE_ALLOW_JFNK is defined)
9    o pkg/thsice:
10      - fix oceanic flux diagnostics & timeave (left from new sequence of calls
11        implementation): move THSICE_AVE call after the advection (called directly
12        from thsice_do_advect.F).
13    o verification/global_ocean.90x40x15 and OpenAD:
14      New experiment for OpenAD is identical to the one in input_ad except that
15        multiDimAdvection=.FALSE.,
16      There is still an issue with this.
17    o pkg/thsice:
18      - account for ice velocity (ocean relative velocity) in turbulent heat flux
19        at the base of the ice; update output of global_ocean.cs32x15 (icedyn)
20        and offline_exf_seaice (main test).
21    
22    checkpoint64f (2013/03/31)
23    o verification/OpenAD:
24      - new (smaller, without OAD_DEBUG) output_oadm.txt generated using gfortran.
25    o verification/isomip, pkg/shelfice and OpenAD:
26      - add OpenAD setup to this exp and make shelfice package work with OpenAD
27    o verification/tutorial_global_oce_biogeo:
28      - update AD and TLM output after turning off ALLOW_FE (in DIC_OPTIONS.h)
29    o verification/offline_exf_seaice:
30      - replace adjoint experiment (now similar to fwd input.thermo/ setup).
31    o verification/tutorial_tracer_adjsens, pkg/ptracers and OpenAD:
32      - add OpenAD setup to this exp and make ptracers package work with OpenAD
33    o pkg/seaice/seaice_evp.F:
34       mask the asymmetric contribution of the ice-ocean stress (when
35       the turningAngle is non-zero) over open water to avoid stripes
36       in the EVP-solutions after many EVP-substeps. This does not change
37       the verification experiment (because turningAngle=0 in that experiment),
38       but will affect other EVP solutions with turningAngle.ne.0
39    o verification, AD & TLM output:
40      - new TAF version 2.3.10 (previously 2.3.8) add more parenthesis in multiple
41        additions and multiplications which affect results at machine truncation
42        level. Update few AD output (1D_ocean_ice_column, bottom_ctrl_5x5,
43        lab_sea.noseaicedyn & offline_exf_seaice) and TLM output
44        (1D_ocean_ice_column & tutorial_tracer_adjsens.som81) which had only 12
45        digits of matching.
46    o pkg/seaice:
47       modify lsr-algorithm so that it vectorizes AND converges by using a
48       "zebra" method: split vector loop into two with step size 2; this
49       solves a general convergence problem for the JFNK solver on a vector
50       computer. It has the potential to even improve convergence for
51       non-vector machines, but it does change the results so it is turned
52       off by default. To turn on define CPP-flags SEAICE_VECTORIZE_LSR and
53       SEAICE_VECTORIZE_LSR_ZEBRA in SEAICE_OPTIONS.h
54    
55    checkpoint64e (2013/03/05)
56    o pkg/ecco and several verification experiments:
57       Remove special versions of the_model_main.F, the_main_loop.F, forward_step.F
58       from ecco package, and revert to unified routine in model/src/
59       Adjust verification experiments accordingly, especially gloal_oce_llc90
60       Should conclude long-standing work by Gael to reconsile the_main_loop with
61       ECCO and will enable OpenAD's revolve loop in ECCO setup.
