This is the system-specific configuration file for the WCOSS Cray Luna machine. Note that Surge has another file, system.conf.wcosssurge

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

[config] — Sets basic configuration options used by all components.
[dir] — Configure directory paths.
[ensdawrf]
[holdvars] — Used when parsing hwrf_holdvars.txt to make storm*.holdvars.txt in COM
[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.
[wrfexe] — This section is read by all scripts that run the wrf or nmm_real.

Section [config]

Sets basic configuration options used by all components.

See the main documentation for [config] for details.

Options in this section:

link_wrf_fix — Copy WRF fix files instead of linking due to Cray's broken symlink implementation

fcst_catalog — Specify the hwrf.input.DataCatalog for FORECAST mode runs.
archive — Archive path

[config] link_wrf_fix

Copy WRF fix files instead of linking due to Cray's broken symlink implementation

1 [config]

2 link_wrf_fix = no

Defined in File parm/system.conf.wcossluna

This option is unused.

Todo:: Remove disk_project or actually use it, in system.conf.wcoss2.

Defined in File parm/system.conf.wcossluna

[config] sync_frequently

Do we run "sync" frequently?

1 [config]

2 sync_frequently = yes

Defined in File parm/system.conf.wcossluna

[config] input_sources

Specify input sources for HISTORY mode.

1 [config]

2 input_sources = wcossluna_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.wcossluna

[config] fcst_catalog

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

1 [config]

2 fcst_catalog = wcoss_fcst_{GFSVER}

Defined in File parm/system.conf.wcossluna

Section [dir]

Configure directory paths.

See the main documentation for [dir] for details.

Options in this section:

utilexec — /nwprod/util/exec directory
utilscript — unused /nwprod/util/ush directory (must exist)
CDNOSCRUB — Non-scrubbed directory for track files, etc. Make sure you edit this.
CDSCRUB — Scrubbed directory for large work files. Make sure you edit this.
CDSAVE — Save directory. Make sure you edit this.
syndat — Syndat directory for finding which cycles to run

[dir] utilexec

/nwprod/util/exec directory

1 [dir]

2 utilexec = {HOMEhwrf}/nwport/util/exec/

Defined in File parm/system.conf.wcossluna

[dir] utilscript

unused /nwprod/util/ush directory (must exist)

1 [dir]

2 utilscript = /

Defined in File parm/system.conf.wcossluna

[dir] CDNOSCRUB

Non-scrubbed directory for track files, etc. Make sure you edit this.

1 [dir]

2 CDNOSCRUB = /gpfs/hps/emc/{disk_project}/noscrub/{ENV[USER]}/trak

Defined in File parm/system.conf.wcossluna

[dir] CDSCRUB

Scrubbed directory for large work files. Make sure you edit this.

1 [dir]

2 CDSCRUB = /gpfs/hps/ptmp/{ENV[USER]}

This is the area where HWRF will actually run. Due to the design of the WCOSS Cray compute and disk, it is critical that you use one of two areas:

/gpfs/hps/ptmp
/gpfs/hps/stmp

All other areas of WCOSS disk are on a different part of WCOSS and cannot handle the load of the full Luna cluster. Using them for I/O-heavy jobs may cause problems.

Defined in File parm/system.conf.wcossluna

[dir] CDSAVE

Save directory. Make sure you edit this.

1 [dir]

2 CDSAVE = /gpfs/hps/emc/{disk_project}/noscrub/{ENV[USER]}/save

[dir] syndat

Syndat directory for finding which cycles to run

1 [dir]

2 syndat = /gpfs/tp1/nco/ops/com/arch/prod/syndat

Defined in File parm/system.conf.wcossluna
