This present forge is now archived and remained online for history.

The big one. Merging all 2019 developments from the option 1 branch back onto the trunk.

This changeset reproduces 2019/dev_r11943_MERGE_2019 on the trunk using a 2-URL merge
onto a working copy of the trunk. I.e.:

svn merge --ignore-ancestry \

svn+ssh://acc@forge.ipsl.jussieu.fr/ipsl/forge/projets/nemo/svn/NEMO/trunk \
svn+ssh://acc@forge.ipsl.jussieu.fr/ipsl/forge/projets/nemo/svn/NEMO/branches/2019/dev_r11943_MERGE_2019 ./

The --ignore-ancestry flag avoids problems that may otherwise arise from the fact that
the merge history been trunk and branch may have been applied in a different order but
care has been taken before this step to ensure that all applicable fixes and updates
are present in the merge branch.

The trunk state just before this step has been branched to releases/release-4.0-HEAD
and that branch has been immediately tagged as releases/release-4.0.2. Any fixes
or additions in response to tickets on 4.0, 4.0.1 or 4.0.2 should be done on
releases/release-4.0-HEAD. From now on future 'point' releases (e.g. 4.0.2) will
remain unchanged with periodic releases as needs demand. Note release-4.0-HEAD is a
transitional naming convention. Future full releases, say 4.2, will have a release-4.2
branch which fulfills this role and the first point release (e.g. 4.2.0) will be made
immediately following the release branch creation.

2020 developments can be started from any trunk revision later than this one.

7! This header file contains preprocessor definitions and macros used in the do-loop substitutions introduced
8! between version 4.0 and 4.2. The primary aim of these macros is to assist in future applications of tiling
9! to improve performance. This is expected to be achieved by alternative versions of these macros in selected
10! locations. The initial introduction of these macros simply replaces all identifiable nested 2D- and 3D-loops
11! with single line statements (and adjusts indenting accordingly). Do loops are identifiable if they comform
12! to either:
13!                                       DO jk = ....
14!   DO jj = ....                           DO jj = ...
15!      DO ji = ....                           DO ji = ...
16!         .                   OR                 . 
17!         .                                      .
18!     END DO                                  END DO
19!   END DO                                 END DO
20!                                       END DO
21! and white-space variants thereof.
22!
23! Additionally, only loops with recognised jj and ji loops limits are treated; these are:
24! Lower limits of 1, 2 or fs_2
25! Upper limits of jpi, jpim1 or fs_jpim1 (for ji) or jpj, jpjm1 or fs_jpjm1 (for jj)
26!
27! The macro naming convention takes the form: DO_2D_BT_LR where:
28!   B is the Bottom offset from the PE's inner domain;
29!   T is the Top    offset from the PE's inner domain;
30!   L is the Left   offset from the PE's inner domain;
31!   R is the Right  offset from the PE's inner domain
32!
33! So, given an inner domain of 2,jpim1 and 2,jpjm1, a typical example would replace:
34!
35!   DO jj = 2, jpj
36!      DO ji = 1, jpim1
37!         .
38!         .
39!      END DO
40!   END DO
41!
42! with:
43!
44!   DO_2D_01_10
45!      .
46!      .
47!   END_2D
48!
49! similar conventions apply to the 3D loops macros. jk loop limits are retained through macro arguments and are not restricted. This
50! includes the possibility of strides for which an extra set of DO_3DS macros are defined.
51!
52! In the following definitions the inner PE domain is defined by start indices of (___kIs_, __kJs_) and end indices of (__kIe_, __kJe_)
53! The following macros are defined just below: ___kIs_, __kJs_, ___kIsm1_, __kJsm1_, ___kIe_, __kJe_, ___kIep1_, __kJep1_.
54! These names are chosen to, hopefully, avoid any future, unintended matches elsewhere in the code.
