[Ncep.list.wwatch3.discussion-group] Development call, Thursday, August 1st 10:30 am Eastern

[Ali Abdolali - NOAA Affiliate]

Hi Everyone,

Just a quick reminder that we will have the development call on Thursday,
which is an overview of the latest developments and discussion on the new
milestones!  Details below:

Thursday, August 1st
10:30 am Eastern

Join hangouts meeting: meet.google.com/pwq-vnuq-ady
Teleconference line: 1-877-953-0315
Passcode: 1262920#

During this meeting, we will have a presentation about the unstructured
grid implicit scheme implementation in WAVEWATCH III. We will also present
a summary of recent developments included in the develop branch and updates
on master branch changes. The meeting will end with an open forum where all
developers can express their ideas and suggestions as well as ask any
questions relevant to the development community.

Presentation Title: Improving Efficiency and Accuracy of WAVEWATCH III on
Unstructured Grids

*Agenda: *



   - Review of recent changes, upcoming changes and current milestones
   (5-10 min)

·       Fix to ad3 has been added to develop:

Bug fix to ad3 where .mod files could be deleted/moved too soon when
running parallel make.

·       Added feature to running regtests: option to specify slurm batch
queue and output compile and runtime metrics added to develop branch:

Timing option *-T* added *to run_test*, option to run batch queue *[slurm]
-b* added to *run_test.*

·       Bugfix in ww3_ounf.ftn: NBIPART check against NOSWLL was not
accounting for zeroth wind partition.

A bug in ww3_ounf is causing the netcdf gridded post-processing wrapper to
fail.

Updating link.wcoss_phase2 for grib compile, removing !$ lines in
ww3_uprstr that broke compilation of codes with OMPH OMPG switch flags,
added new global wave model switch. Added option for writing to fixed
netcdf gridded output file when using NCO switch (the issue will be fixed
more adequately in v7.

·       Depth-breaking_bugfix: added proper scaling coefficients for radian
freq. [radHz]:

DB1 module was originally coded using the monochromatic wave dissipation
dimensional variables. It was updated to use the spectral form, but some
coefficients were no updated accordingly which resulted in a
dimensionally-incorrect version.

·       *upcoming changes**:*

§  Ifremer: Fixing Issues with namelists.

§  NCEP: Code cleanup and meeting standards (still open!).

§  ERDC: Smaller memory usage for the PDLIB, Unset variables, Different
memory size (10 vs 13) in the variable GRDID.

·       Please consider that developers should be forking and creating all
development branches from the develop branch, not the master.

   -   Coding standards (10-15min)

·       An introduction to the existing guide and wiki pages.

·        Brandon Reichl presents on standards and expectations.

   -    Presentation:  Improving Efficiency and Accuracy of WAVEWATCH III
   on Unstructured Grids (20-25 min)


   -    Open discussion


See you tomorrow,
Regards,
AA
