Minutes
Actions from the Last Meeting (LA)
Minutes of the code management group meeting 2016-09-23
- (ongoing) GM to check 8.4 versus 7.3 (and possibly vn8.4 vs 10.x) GLOMAP-mode code and report any missing bug fixes on the bugfix page.
- (ongoing) FOC to incorporate Bug #35 and others into dry deposition work
- (ongoing) LA to migrate PUMA UM tickets to MOSRS
- (ongoing) UM #368 (RAFEPS value). Error not encountered at UM10.x but LA to consult Oliver Wild regarding background and implications.
- (ongoing) LA to check doc for NVOC factor and open ticket to remove it from code
- (ongoing) CJ to lodge STASHmaster changes to diagnostics that should make use of UKCA time availability codes
- (ongoing) CJ,FOC,AH,AS,LA and John H to decide best way forward for implementing GLOMAP-climatology code and documentation.
- (ongoing) JM,BJ,NB to discuss incorporation of Nicolas' RADAER description into UKCA (or separate UMDP). JM to take lead.
- (ongoing) FOC to open ticket + Bugfixes Table entry related to 'Unable to calculate tropopause' warnings
- (updated) MD to setup Strat+Trop suite as soon as GA7.1 is frozen and also add to Rose-stem. MD set-up/replace current Rose stem job with GA7.1 jobs.
- (ongoing) CJ to involve NS in discussions with Dynamics and UM-sys teams regarding movement of UKCA call, for effective implementation of water vapour feedback.
- (ongoing) FOC to recommend at next Exec meeting a policy of allowing only CMG to (certify and) distribute any UKCA configurations for science purpose.
- (new) MD to chase CMS about MASS archiving
- (new) NS to collate all code that could be removed and put on Wiki
- (new) LA to do doodle poll for end of Nov/ start of Dec
Standing actions
- (ongoing - standing item) CMG to monitor list of bugs and circulate between group for owners.
- (ongoing - standing item) At CMG future meetings there should be included an appendix listing the open bugs. If a ticket is included it is not an open bug (as the owner of ticket is person doing lodging).
- (ongoing - standing item) JM to continue to link/send powerpoint results (re: GA7.0/GA7.1), as new configurations released and link/put files on UKCA wiki.
- (ongoing - standing item) ALL with access to keep monitoring ukca_bugs email list.
- (ongoing - standing item) ALL to think about if code changes will change KGO and let systems team know in good time. This should be a standard part of our working practice.
- (ongoing - standing item) ALL to review and remove obsolete code

What is required now to move UKCA recommended jobs up to GA7.1? (CJ)
Highlights from vn10.8 (LA)
vn10.8 UKCA tickets
UMPB May 2017 Highlight Report
- CJ: Water vapour feedback - This includes flux calculations of water production and loss available in stash, as well as a diagnostic which gives the change to q calculated at each timestep. (#1646 & #3123)
- LA: Quasi-Newton steps in Newton-Raphson solver - speeds up the model by ~2-3%. Will not bit-compare with runs without it however. (#2819)
- MR: OpenMP in UKCA_AERO_CTL - alternative method for passing array slices to sub processes, e.g. a(:,:,:,mode) had to be re-written a(1,1,1,mode) for the combination of Linux system SPICE and Intel ifort 12. (#1286 )
- MR: OpenMP in UKCA_AERO_CTL - a bespoke workshare had to be written due to ONE failure in rose stem. The formal method that used the default blocking of data failed. Again Linux and Intel 12. (#1286 )
- LA: 3 new UKCA rose-stem tests were added to the MetO XC40. This tests mirror the ones available on the VM, but run incredibly quickly. One has been added to the
xc40_developer
group -meto_xc40_n48_ukca_eg_omp_noios_gnu
. (#2714)- Note: On the XC40 the
_omp
and_noomp
jobs do not bit-compare, whereas they do on the VM. The version of the GNU compiler is different between these two sites - the XC40 uses GNU Fortran (GCC) 4.9.1 20140716 (Cray Inc.), whereas the VM uses GNU Fortran (Ubuntu 5.2.1-22ubuntu2) 5.2.1 20151010. The domain decomposition is different as well (4x4 on the XC40 vs. 1x{{MPI_TASKS}} on the VM). #3127 has been opened to investigate this.
- Note: On the XC40 the

I am currently working on testing the code with different MODE setups and then will work on going through the required steps to get the code into the trunk at 10.9 (sci/tech review, code review, etc). All being well the updates should hopefully be ready for 10.9 (fingers crossed).
