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.

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)).

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 {{ hilight }}case_name{{ closehilight }}.
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.

List of full pathnames of elevated emission (or external chemical forcings) datasets.
The chemistry package reads in elevated emission data from a set of netcdf files in
units of "molecules/cm3/s". Each tracer species emissions is read from its
own file as directed by the namelist variable {{ hilight }}ext_frc_specifier{{ closehilight }}. The
{{ hilight }}ext_frc_specifier{{ closehilight }} variable tells the model which species have elevated
emissions and the file path for the corresponding species. That is, the
{{ hilight }}ext_frc_specifier{{ closehilight }} variable is set something like:
ext_frc_specifier = 'SO2 -> /path/vrt.emis.so2.nc',
'SO4 -> /path/vrt.emis.so4.nc', etc...
Each emission file can have more than one source. When the emission are
read in the sources are summed to give a total emission field for the
corresponding species. The emission can be read in as time series of data,
cycle over a given year, or be fixed to a given date.
The vertical coordinate in these emissions files should be 'altitude' (km) so that the
vertical redistribution to the model layers is done using a mass conserving method.
If the vertical coordinate is altitude then data needs to be ordered from the
surface to the top (increasing altitude).

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

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.

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)).

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 {{ hilight }}case_name{{ closehilight }}.
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.

List of full pathnames of elevated emission (or external chemical forcings) datasets.
The chemistry package reads in elevated emission data from a set of netcdf files in
units of "molecules/cm3/s". Each tracer species emissions is read from its
own file as directed by the namelist variable {{ hilight }}ext_frc_specifier{{ closehilight }}. The
{{ hilight }}ext_frc_specifier{{ closehilight }} variable tells the model which species have elevated
emissions and the file path for the corresponding species. That is, the
{{ hilight }}ext_frc_specifier{{ closehilight }} variable is set something like:
ext_frc_specifier = 'SO2 -> /path/vrt.emis.so2.nc',
'SO4 -> /path/vrt.emis.so4.nc', etc...
Each emission file can have more than one source. When the emission are
read in the sources are summed to give a total emission field for the
corresponding species. The emission can be read in as time series of data,
cycle over a given year, or be fixed to a given date.
The vertical coordinate in these emissions files should be 'altitude' (km) so that the
vertical redistribution to the model layers is done using a mass conserving method.
If the vertical coordinate is altitude then data needs to be ordered from the
surface to the top (increasing altitude).
