end of each month or at the end of each year by using the options

restart files be written via the option 'none', or that restart files be
written only at the end of the run via the option 'end'.

Default: set to shr_const value

Array of history filename specifiers.  The filenames of up to six history
output files can be controlled via this variable.  Filename specifiers give
generic formats for the filenames with specific date and time components,
file series number (0-5), and caseid, filled in when the files are
created. The following strings are expanded when the filename is created:
%c=caseid; %t=file series number (0-5); %y=year (normally 4 digits, more
digits if needed); %m=month; %d=day; %s=seconds into current day; %%=%
symbol.  Note that the caseid may be set using the namelist
variable case_name.

For example, for a simulation with caseid="test" and current date and time
of 0000-12-31 0:00UT, a filename specifier of "%c.cam2.h%t.%y-%m.nc" would
expand into "test.cam2.h0.0000-12.nc" for the first history file.  The
filename specifier "%c.cam2.h%t.%y-%m-%d-%s.nc" would expand to
"test.cam2.h1.0000-12-31-00000.nc" for the second history file. Spaces are
not allowed in filename specifiers. Although the character "/" is allowed
in the specifier, it will be interpreted as a directory name and the
corresponding directories will have to be created in the model execution
directory (directory given to configure with -cam_exedir option) before
model execution.  The first element is for the primary history file which
is output by default as a monthly history file.  Entries 2 through 6 are
user specified auxilliary output files.

Defaults: "%c.cam2.h0.%y-%m.nc", "%c.cam2.h1.%y-%m-%d-%s.nc", ...,
          "%c.cam2.h5.%y-%m-%d-%s.nc"

Frequency that initial files will be output: 6-hourly, daily, monthly,
yearly, or never.  Valid values: 'NONE', '6-HOURLY', 'DAILY', 'MONTHLY',

Default: 2,2,2,2,2,2

 
Array specifying default history buffer precision for each history file
series. Valid values are 4 or 8. '4' implies history buffers use 4-byte
reals and and '8' implies history buffers use 8-byte reals.  These default
settings are overridden for particular fields via the fhstpr1,
... fhstpr6 variables.
Default: 8,8,8,8,8,8

 

Array of write frequencies for each history file series.
If nhtfrq(1) = 0, the file will be a monthly average.

nhtfrq(i) > 0, frequency is specified as number of
timesteps.  If nhtfrq(i) < 0, frequency is specified

Default: 0

Default: 0

Geopotential method 2 pipeline parameter (routine geopk_d).
geopk_d implements a pipeline algorithm by dividing the 
information that must be moved between processes into blocks. geopkblocks
specifies the number of blocks to use. The larger the number of blocks,
the greater the opportunity for overlapping communication with computation
and for decreasing instantaneous bandwidth requirements. The smaller the
number of blocks, the fewer MPI messages sent, decreasing MPI total latency.
See geopk_d within geopk.F90.
Default: 1

Geopotential method (routines geopk, geopk16, or geopk_d).
0 for transpose method, 1 for method using semi-global z communication 
with optional 16-byte arithmetic, 2 for method using local
z communication; method 0, method 1 with 16-byte arithmetic and method 2 
are all bit-for-bit across decompositions; method 0 scales better than 
method 1 with npr_z, and method 1 is superior to method 0 for small npr_z.
The optimum speed is attained using either method 1 with 8-byte 
arithmetic (standard for geopk16) or method 2 when utilizing the 
optimal value for the associated parameter geopkblocks; for the last 
two subcycles of a timestep, method 0 is automatically used; see 
geopk.F90 and cd_core.F90.

A four element integer array which specifies the YZ and XY decompositions.
The first two elements are the number of Y subdomains and number of Z
subdomains in the YZ decomposition.  The second two elements are the number
of X subdomains and the number of Y subdomains in the XY decomposition.
Note that both the X and Y subdomains must contain at least 3 grid points.
For example, a grid with 96 latitudes can contain no more than 32 Y
subdomains.  There is no restriction on the number of grid points (levels)
in a Z subdomain, but note that the threading parallelism in the FV dycore
is over levels, so for parallel efficiency it is best to have at least the
number of levels in each Z subdomain as there are threads available.

There are a couple of rough rules of thumb to follow when setting the 2D
decompositions.  The first is that the number of Y subdomains in the YZ
decomposition should be the same as the number of Y subdomains in the XY
decomposition (npr_yz(1) == npr_yz(4)).  The second is that the total
number of YZ subdomains (npr_yz(1)*npr_yz(2)) should equal the total number
of XY subdomains (npr_yz(3)*npr_yz(4)).

Default: 0

Number of vertical re-mapping timesteps per physics timestep.
Nspltrac is partitioned into nspltvrm and nspltrac/nspltvrm,
