File parm/system.conf.theia

This is the system-specific configuration file for the NOAA Theia cluster. It should not be used directly. Users should copy it to parm/system.conf and edit the values manually.

This is a configuration override file. This file sets options in the following sections:

Section [wrf]

Set a few variables that the Python code must be aware of to communicate correctly between HWRF components. These will also be used to calculate or set the appropriate WPS and WRF namelist values:

See the main documentation for [wrf] for details.

Options in this section:

[wrf] io_form

Use io_form=2 on Theia because I/O servers are disabled and NetCDF is faster.

1 [wrf]
2 io_form = 2

Defined in File parm/system.conf.theia

Section [config]

Sets basic configuration options used by all components.

See the main documentation for [config] for details.

Options in this section:

[config] input_sources

Specify input sources for HISTORY mode.

1 [config]
2 input_sources = theia_sources_{GFSVER}

Specifies input sources for use by hwrf.input.InputSources. In a HISTORY mode run, this will be used in the scripts.exhwrf_input job to pull data.

Defined in File parm/system.conf.theia

[config] fcst_catalog

Specify the hwrf.input.DataCatalog for FORECAST mode runs.

1 [config]
2 fcst_catalog = theia_fcst_{GFSVER}

Defined in File parm/system.conf.theia

[config] archive

Archive path

1 [config]
2 archive = hpss:/NCEPDEV/emc-hwrf/1year/{ENV[USER]}/{SUBEXPT}/{out_prefix}.tar

Defined in File parm/system.conf.theia

Section [holdvars]

Holdvars variable generation section. This sets variables that are only used to create the holdvars file for ksh. Nothing in this section is ever used by the Python code. That vestigial file is just for compatibility with legacy external workflows, and it will be removed eventually. The external workflows that need it are: HHS - to decide whether things failed graphics scripts - for data paths Note that you must also edit parm/hwrf_holdvars.txt in order for the values in this section to be sent to the holdvars.txt file.

See the main documentation for [holdvars] for details.

Options in this section:

[holdvars] WHERE_AM_I

Which cluster? (For setting up environment.)

1 [holdvars]
2 WHERE_AM_I = theia

Defined in File parm/system.conf.theia

[holdvars] WHICH_JET

Which part of Jet are we on? None; we are not on Jet.

1 [holdvars]
2 WHICH_JET = none

Defined in File parm/system.conf.theia

Section [runwrf3km]

Special configuration for 3km on Theia: no I/O servers

This overrides the default runwrf3km to remove I/O servers. This is needed even at 3km because of IMPI bugs on Theia.

Options in this section:

[runwrf3km] nio_tasks_per_group

Number of servers per group in the forecast job

1 [runwrf3km]
2 nio_tasks_per_group = 0,0,0

Defined in File parm/system.conf.theia

[runwrf3km] wrf_ranks

Total number of WRF processors

1 [runwrf3km]
2 wrf_ranks = 184

Defined in File parm/system.conf.theia

Section [wrfexe]

This section is read by all scripts that run the wrf or nmm_real.

See the main documentation for [wrfexe] for details.

Options in this section:

[wrfexe] nio_groups

Number of WRF I/O server groups per domain in init jobs

1 [wrfexe]
2 nio_groups = 1

Defined in File parm/system.conf.theia

[wrfexe] nio_tasks_per_group

Number of I/O servers per group in init jobs

1 [wrfexe]
2 nio_tasks_per_group = 0,0,0

Defined in File parm/system.conf.theia

[wrfexe] poll_servers

Turn on server polling in init jobs if quilt servers are used (They are not.)

1 [wrfexe]
2 poll_servers = yes

Defined in File parm/system.conf.theia

[wrfexe] nproc_x

Init job WRF processor count in X direction (-1 = automatic)

1 [wrfexe]
2 nproc_x = -1

Defined in File parm/system.conf.theia

[wrfexe] nproc_y

Init job WRF processor count in Y direction (-1 = automatic)

1 [wrfexe]
2 nproc_y = -1

Defined in File parm/system.conf.theia

Section [runwrf]

This section is read by the script that runs the WRF forecast job at 2km. It is not used by other executions of wrf. See runwrf3km for the 3km configuration.

See the main documentation for [runwrf] for details.

Options in this section:

[runwrf] nio_groups

Number of WRF I/O server groups per domain

1 [runwrf]
2 nio_groups = 1

Defined in File parm/system.conf.theia

[runwrf] nio_tasks_per_group
