7    o eesupp/src:
8      - add an other alternative for multi-proc GLOBAL_SUM (in global_sum_tile.F)
9        to always cumulate tile local-sum in the same order
10        (option #define GLOBAL_SUM_ORDER_TILES in CPP_EEOPTIONS.h).
11        Still uses MPI_Allreduce (like standard code) but on array of tiles
12        and should be faster than GLOBAL_SUM_SEND_RECV code.
13      - switch almost all verification experiments that use GLOBAL_SUM_SEND_RECV
14        (defined in CPP_EEOPTIONS.h_mpi) to GLOBAL_SUM_ORDER_TILES instead.
15      - add CPP_EEOPTIONS.h_mpi with GLOBAL_SUM_ORDER_TILES defined in 13 more exp.:
16         aim.5l_cs, cheapAML_box, deep_anelastic, dome, fizhi-cs-32x32x40,
17         fizhi-cs-aqualev20, global_ocean_ebm, matrix_example, natl_box,
18         solid-body.cs-32x32x1, tutorial_advection_in_gyre, tutorial_baroclinic_gyre
19         and tutorial_held_suarez_cs.
