Philippe 29/08/2023: OpenACC: work around for a problem with NVHPC 23.7 (not present in older versions)

(cherry picked from commit ce39d7dc)

Philippe 26/06/2023: ice4_sedimentation_split: remove a DO CONCURRENT because of a reduction in loop (wrong reults with NVHPC 23.5)

(cherry picked from commit ad799fd0)

(cherry picked from commit 18a466fd)

Juan 19/06/2023:rain_ice_sedimentation_split.f90, Again SegFault at execition with CRAY ftn -> deactivate mnh_expand_array for CRAY ftn !!!

Juan 19/06/2023:rain_ice_sedimentation_split.f90, For pref PB with nvhpc , reintroduce mnh_expand_array & MNH_MEM_GET(ZRTMIN...) + replace data create -> present

Juan 16/06/2023:MNH/* , For Nvhpc , remove duplicate "!$acc loop" introduced by use of mnh_do_conncurrent

Juan 16/06/2023:rain_ice_sedimentation_split.f90, Strange Cray SegFault -> replace mnh_do_concurrent -> array syntax

Juan 13/06/2023:ice4_sedimentation_split.f90 , For gfortran+openacc ,replace DO CONCURRENT -> mnh_do_concurrent

Juan 13/02/2023: MNH modif for compile with sourceryg/2022.09-7-orig+OPENACC + optimization for CRAY ftn

Juan 20/03/2023:ZSOLVER/turb_hor_uv.f90, Bypass Nvhpc BUG <->  zflx partially present/error 700: Illegal address during kernel execution <-> remove "acc loop ..." & replace DO CONCURRENT -> mnh_do_conccurent , better perf

Juan&Naima 16/03/2023:MNH/advec_weno_k_3_aux.f90,bl89.f90,ice4_sedimentation_split.f90, Cray OpenACC opt , add present_cr to avoid recurrence in kernels

Juan 07/03/2023:slow_terms.f90, Bypass CRAY CCE/15.0.1 compiler bug => remove size(...) in kernels + use MNH_MEM_GET

Juan 17/02/2023:mode_mnh_zwork.f90+modd/n_confz.f90 , put size of T1DFLAT buffer = NPMAX_T1DFLAT_R in namelist NAM_CONFZ , for augmentaton without recompiling the code

Juan 16/11/2022:MNH/tridiag_wind.f90, Cray/14.X optimization , replace DO CONCURRENT with !$mnh_do_concurrent & put Z "acc seq loop" inside parallel 2D_XY one

Juan 16/11/2022:MNH/rain_ice_nucleation.f90,Nvhpc 22.X Bug Bypass , "ZZWMAX=MAXVAL()" dont parallelize any-more in GPU -> replace by "!$acc ... reduction(max:ZZWMAX)"

Juan 04/11/2022:tools.f90, BYpass CCE > 14.X , "acc atomic" needed now "copy(ic)" to get corretly the ic value

Juan 04/11/2022:MNH/rain_ice_red.f90, ATTENTION , for CCE > 14.X, temporarely inhibe compilation of rain_ice_red, MORE THEN 30 minutes

Juan 04/11/2022:ice4_sedimentation_split.f90, Bypass for CCE > 14.X && nvidia70 target <=> TARGET_NV70 , use MODI_GAMMA

Juan 04/11/2022:MNH/tridiag*.f90, CCE Optimization, use "!$acc parallel" to avoid multiple kernel lunch inside seq loop

Juan 04/11/2022:Bitrep PB , missing some MNH_BITREP_OM in MNH or ZSOLVER soource to have bitreproductibility beetwen MASTER & USER versions

Juan 27/10/2022:turb_hor_thermo_corr.f90, Strange BUG with Nvhpc/22.7+ , turb+I/O do SegFault => convert array syntax adding mnh_expand to eliminate listing reference to zflx$f/zwork$f

Juan 26/10/2022:mode_mnh_zwork.f90, For Grand Challenge , more variables needed on GPU , upgrade JPMAX_T1DFLAT_R = 120 => 300

Juan 26/10/2022:MNH/rain_ice*rg/rs.f90, Cray CCE/14.0.3++ Optimsation Problems , replace some "acc kernels" with "acc parallel" + some present_cr

Juan 26/10/2022:MNH/*, Cray CCE/14.0.3++ Optimsation Problems , add present_cr & minor kernels restructuration

Juan 26/10/2022:condensation.f90, BIG BUG CORRECTION, missing "ZCOND = ZCOND * ZSIGMA" term since merge with MNH-55-branch in 2021-09-06

Juan 21/09/2022:rain_ice*.f90, GPU nvhpc/cray optimization , add mnh_do_concurrent for nvhpc + mnh_undef(LOOP/OPENACC) for cray
