Items from Hilary Oliver's visit
-
BNOC plan to build up experience re Cylc (Jim Fraser).
-
Arn keen to explore Cylc & EcFlow.
-
Refer job scheduler issues to NWP Suites Working Group (Yi Xiao).
-
Jin Lee: Recommend using Rose layout and features for NWP suite design.
-
Fabrizio: Importance of moving to common working environment and practices for research and operations, including proper use of svn branching.
-
Fabrizio: What are the key differences between fcm and svn?
- Hilary: fcm imposes standard naming, project structure; fcm is compatible with rosie; fcm commit includes trac commit messages.
-
Joan: svn can't handle large files.
- Can use ~access plus config references in rose app config files.
- Could use git for config management of large files.
-
Ivor: BoM svn training.
- BNOC requesting svn training from ISS.
-
Asri: Not completely happy with Met Office working practices.
- MO don't use tags. Hilary: Can use tags.
- MO use specific naming convention for branches. Hilary: Used to be bothered by this too; now find conformance to common naming format is better than varying. Rosie searches also useful for organising.
-
Worth continuing to try to improve our working practices; compare with and learn from Met Office and others.
-
Standardisation and sharing of conversion tools was briefly discussed.
-
Packing efficiences of different data formats was raised: nc, grib, hdf.
-
Jin Lee: Using Iris with BoM grib files from Mars; questions arise re which table to use
- Some people who might be worth checking with on this: Tan Le, Mark Hedley, Ivor B, Martin D, Gary D, Lawrie R.
