remove unnecessary BARRIER
change macros (EXCH & GLOBAL_SUM/MAX) sufix _R4/_R8 to _RS/_RL when applied to _RS/_RL variable
rename OBCS_CHECK_TOPOGRAPHY -> OBCS_CHECK_DEPTHS + call EXCH2_CHECK_DEPTHS
OCEANICP: conversion from z to bottom pressure is not coded => STOP
clean up the mess: remove call of removed subroutine shelfice_ini_depth
- move code for reading ice shelf topography and modifying hFacC into separate subroutines of the shelfice package
add hook for code to fix topography gradients normal to open boundaries
add ability to read bathy, salt, and theta using MNC (off by def) -- and this can be readily extended to most of the other files in PARM05 of the main "data" namelist file
clean-up multi-threaded problems (reported by debugger tcheck on ACES).
call PLOT_FIELD R_low & Ro_surf only if debugLevel >= 2 (since there is a 2nd call in ini_mask_etc)
- initialize R_shelfIce (overlap regions were not); - all threads call READ_FLD S/R (needed if using SingleCpuIO); - add barrier before reading (and after initialisation);
o add hooks for new package shelfice, painless
Comment PRINT *
Changes toward getting exf working multi-threaded.
o added some opitonal consistency check in barrier for
trapping barrier calls in singel threaded region
o removed a single thread block in ini_depths - singleCpuIO
still broken.
o modified parts of exf_ that were setting local stack variables
in single threaded section and then referencing them from all
threads.
o commented out strange stop in mdsio for multithreading which
seems uneeded.
o fixed ptracers initialization and changed ptracers monitor
to avoid race condition in which several threads set a shared
logical flag at arbitrary moments with respect to each other
Added some _BARRIER statements to get correct multi-threaded behavior for initializations followed by master thread I/O.
"usingPCoords" replaces "groundAtK1" (<- removed)
Slight re-arrangment to satisfy JMC opinions on file names!
o ini_mnc_io.F has been split and replaced by
ini_model_io.F - responsible for setting units/flags for model-state i/o
write_grid.F - responsible for writing the grid variables to file
o the passing of flags to MDSIO has been moved from ini_parms to ini_model_io
o ini_depths and ini_masks_etc no longer do I/O which is now in write_grid
improve definition of Po_surf when using Finite Volume form to integrate PhiHyd and (standard) vertical grid (Center at middle).
* allows a more accurate definition of Ro_Surf (selectFindRoSurf=1) when using P-coordinate; only implemented for atmospheric config.
modification needed for the new AIM package (aim_v23)
Bringing comments up to data and formatting for document extraction.
exchange R_low and Ro_surf to get the same mask as before (cube corners).
read orography (in m) from file and convert to Surface Pressure (Ro_surf)
Merge from branch pre38: o essential mods for cubed sphere o debugged atmosphere, dynamcis + physics (aim) o new packages (mom_vecinv, mom_fluxform, ...)
Made sure each .F and .h file had the CVS keywords Header and Name at its start. Most had header but very few currently have Name, so lots of changes!
Merged changes from branch "branch-atmos-merge" into MAIN (checkpoint34) - substantial modifications to algorithm sequence (dynamics.F) - packaged OBCS, Shapiro filter, Zonal filter, Atmospheric Physics
Removed unused variables and fixed some unitialized variables.
Implemented new I/O package (mdsio.F). This package does parallel
I/O in much the same way as dfile.F used to except it uses "direct
access" rather than (f77) unformatted sequential access.
Problems with dfile.F package included:
o unnecessary memory use (each process had two global sized buffers)
o inability to read the files it had written without post-processing
o "tiled" files were tiled by process/thread rather than actual tiles
o created huge numbers of files with no alternatives
Features of the mdsio.F package:
o direct-access binary writes
o no excessive memory use
o ability to read/write from multiple record files
o "tiled" files are based on "WRAPPER" tiles so that the number
and content of files is independent of the number of threads
and/or processes
o option to create single "global" files rather than "tiled" files
o ability to read both "global" and "tiled" files
[Caveat: the tiling of files must match the model tiles]
o checkpoints now use a single file per model section
ie. one file for the hydrostatic model core, one file
for the non-hydrostatic extensions and one file for the C-D
extensions
o the mid-level I/O routines now is broken into more source files
read_write_fld.F supplies basic I/O routines with the same interface
as the original I/O package
read_write_rec.F supplies I/O routines which allow multiple records
write_state.F writes the model state
checkpoint.F supplies the read/write checkpoint routines
All the example input data has had to be modified to be direct-access.
Otherwise only routines that used I/O have been affected and not
all of those have been due to the continuity of arguments in
the read_write_fld.F routines.
What needs to be done? We have to create a suite of conversion
utilities for users with old-style data. Also supply the option
for using old-style I/O, not just for die-hards but for reading
data too extensive to be converted. And more...
o Added "natural BCs" as alternative to "virtual salt flux" o Re-difined precFloat32 and precFloat64 to be 32 and 64 so that their values can be meaningfuly set in the data file o Modified read_write.F to create an exception if readBinaryPrec is not set o Replaced CPP control of viscous BCs with run-time control o Tidied up input-data precision (ie. ini_depths cnh_dbg...) o ini_forcing.F now initialises *all* forcing arrays to zero o Definitively tested verification experiments 0,1,2 and 4 (3 is atmospheric set-up which is in a state of flux)
Added IMPLICIT NONE in a lot of subroutines. Also corrected the recip_Rhonil bug: we didn't set it in ini_parms.F
Changes to allow for atmospheric integration builds of the code
Changes to support - g77 compilation under Linux - LR(1) form of 64-bit is D or E for constants - Modified adjoint of exch with adjoint variables acuumulated.
Changes for new exchange routines which do general tile <-> tile connectivity, variable width overlap regions and provide hooks for shared memory and DMA protocols like Arctic, Memory Channel etc..
Consistent isomorphism changes
Isomorphism consistency changes
Correction to -H switch that was inconsistent eith exp2 topography dataset
This is a bit confusing. We use Z coordinates with Z=0 at the top and z=H at the bottom. The depth of the model (internally) is positive but we wanted to use negative depths for input files. That way we can use the same bathymetry file for the atmospheric model which would have positive elevation for the bottom boundary. Oh boy! I've added a sign change immediately after the read of bathyFile to make this work but we ought to write this all down somewhere...
Forgot this changes to ini_mask_etc() and ini_depths() in the previous "rearrangement" of initialise().
Re-arrangment of initialisation: o ini_grid is now called first and it sets up *only* the grid and coordinate system. o ini_depths then reads topography are can set it as a function of xC, yC. o ini_masks_etc then derives everything else (masks, lopping factors and recipricols). This tidy-up is in preparation for the rDot transformation...(tense pause)!
Fairly coplete 4 degree global intercomparison setup. Includes changes to make convective adjustment and hydrostatic pressure correct as well as IO for climatological datasets
Chages to make default setup correct for 4 degreee global comparison
Fixed problems with _RS -> REAL*4 and with reading in intial hydrography
Changes to support topography, hydrography and forcing from files
Merge of GM Redi and spherical polar and inplicit diffusion and CD. Everything for a global run is now included, however, still some discrepancies with GM Redi.
Further $Id to $Header conversions
