Welcome to Ed Habjan from Oracle attending as observer
- Suites: AG1, AR1, AC1, Disk Mgmt
- Executables: Build Documentation, Time Variation, Diagnostics
- Project Management
- Items from task list
- Other Business
-
DISK usage
-
Details to be discussed between relevant parties
-
ACTION: On-going monitoring
-
Plots
-
Plots now available at close to real time.
-
mjn had look at plot and it lookes comparable to APS1 & AGREPS ensemble members -- OK
-
Gary's diagnostics
-
mjn to discuss with Gary
-
NMOC AG1 suite (Joan)
-
Progressing ... minor problems needed solving
-
Output fields from NMOC AG1 will be archived in MARS7OP
-
MARS retrieval script (mars.sh): NMOC to resolve the scripting
-
Wenming to produce plots when suite trial is going into MARS
-
Verify on ngamai not yet available (can still verify on solar in meantime)
- Restarted because pressure level output was missing
- Have re-run 3 weeks from mid-June
- Initial verification using laps-verif indicated acceptable results
- Joerg having problem running Xiao's script for run time-variation investigations
- Have run March-April period
- Delayed by MARS issues
- Plots have been done which look OK, but no similar data to compare it with
- Rainval plots to be done
- MARS archive id has be set to ngaX
- Switch to current test period from late-June onwards
- use data from Xiao's ngamai AR1 -- 2-3 weeks of data already available
- Runtime variation
- Plus/minus 5% was observed
- Compared to solar, which had 5-20% variation, fluctuating month to month
- Currently setting up on ngamai; no problems
- Non-porting issues relating to ACCESS-TC to be discussed in ACCESS-NWP WG
- Performance -- runtime variation
- UKV reruns from a couple of months ago on solar now takng 30-40% longer
- Joerg still investigating issue with swap_bounds_mv
- Different MPI library is used on solar
- Ilia's test config is to do 2 runs within the same job
- i.e. identical set of nodes are used - test setup suggested by David Singleton
- On ngamai, second run usually takes considerably longer
- first runs usually ~ 10% variation
- second runs more variation, up to 100%
- Joerg seeing similar variations
- On vayu, 2nd runs can be faster
- On solar and raijin - no change
- Reconfig runs taking between 3.5 to 20 minutes
- Suggest "sleep" between two jobs to give time for flushing of buffers.
- Lustre striping being investigated
- Documented build
- Changes to UMUI required to include command to use PRG_ENV
- VAR & OPS uses build procedure outside of VARUI/OPSUI
- Method to handle VAR/OPS sources to be decided
- ACTION: azs to continue and follow up with relevant parties regarding build procedures and documentation, and set up initial wiki page
- Updated ghui2.0 to solved bigfont issue implemented on ngamai
- Some problems remain. azs following up together with Say
- rab providing updates on this WG progress to higher management
- Further documentation on steps required, rab to email people
- Some project documentation available through the network: url or s-drive location to be sent, or put on the wiki
- python modules being finalised
- verify and metpy also being installed
- link for /apps documentation is on NMOC wiki: http://nmoc-svnop.bom.gov.au:8080/
- NMOC wiki pages on SVN repository and the new SMS being used on Ngamai -- http://wiki.bom.gov.au/foswiki/NMOC/SoftwareSystems/NgamaiPortIntro
- Robin to report to OSICG
- Met Office TI collaboration project TAG video-conf last week
- RDSI setup at NCI -- Repository for datasets of national significance
- ACCESS NWP, Seasonal, Climate
- Several Petabytes available in NCI /gdata
- Historical and future
- Analyses/forecasts
- Start thinking of copying data from ngamai to NCI directly rather than going through sam
- NetCDF format down the road
- openmp course
- Resume UMWG meetings to broaden the scope to this meeting beyond ngamai porting to ngamai/raijin/accessdev and other aspects
- Suspend/resume being worked-on on ngamai
- MPI library with "THREAD_SERIALIZED" only available with intelMPI on raijin; Ilia investigating
- Team members leave plans
- Items from task list?
