File parm/system.conf.wcoss2

This is the system-specific configuration file for Phase 2 of the NOAA WCOSS 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:

• [config] — Sets basic configuration options used by all components.
• [dir] — Configure directory paths.
• [holdvars] — Used when parsing hwrf_holdvars.txt to make storm*.holdvars.txt in COM
• [hwrfdata] — HWRF staging area paths. See hwrf.input.DataCatalog for details.
• [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 [hwrfdata]

HWRF staging area paths. See hwrf.input.DataCatalog for details.

See the main documentation for [hwrfdata] for details.

Options in this section:

• inputroot — Use a multi-user shared staging area to reduce HPSS usage

[hwrfdata] inputroot

Use a multi-user shared staging area to reduce HPSS usage

[hwrfdata]
inputroot = /hwrf2/noscrub/input/hwrfdata/

This setting overrides the normal location for staging HPSS files. We use a multi-user shared area to avoid duplicate transfers.

[dir]
utilscript = /nw{ENV[envir|-prod]}/util/exec

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

[dir]
CDSCRUB = /ptmpp2/{ENV[USER]}

This is the area where HWRF will actually run. Due to the design of the WCOSS Phase 2 compute and disk, it is critical that you use one of two areas:

• /ptmpp2/
• /ptmpd3/

All other areas of WCOSS disk are on a different WCOSS phase. Using them for I/O-heavy jobs may cause problems.

Defined in File parm/system.conf.wcoss2

[dir]
