• Items from previous meeting notes
• AOB

• AG-1 now archiving to MARS from ngamai.
• AR-1 pi files not being kept.
  • May send pi files to raijin for SREP, or produce pi files required by SREP on the fly?

• AG-1 Went operational on ngamai yesterday.
• First operational system on ngamai.
• Running in new NMOC SMS scheduler.
• Relatively smooth changeover.
• AG-1 suite on solar changed to "test".
• More output products being switched on today.
• Run times still good after all postprocessing task turned on.
• Gary's diagnostic - work in progress, mjn following up; aim to run for all systems.

• Hourly archive to MARS for first 24 hours, then 3-hourly for multi-level fields.
  • All surface fields are archived hourly.
• Data extraction task now done on ngamai - executing in real-time.
• SST generation also using real-time input.
• Downstream output products still to be done.
  • Since it uses similar scripts to ACCESS-G, no problems expected.
• Plan to make AR-1 operational on ngamai in 1 week's time.
• Development AR1
  • work in progress - ciwt now running, but not routinely yet.

• Now running in real-time
• Verification of surface fields to be done (Xiaoxi); ditto for Rainval.
• Some data from not AR-1 runs not ingested to MARS due to problems. Data kept on disk, to run ingestion manually when time permits.
  • Due to disk problems releated to NFS issues making I/O performance very bad.
  • Oracle investigating the problem.
• MARS client on solar not working - to catch up using Ngamai.
• ADN also being archived into MARS.

• Joan has made considerable progress in getting ATC-1 ready to run on ngamai.
  • Requires final check of all scripts and components.
  • Aim to get it running first and leave "Big-Domain" ancillary reconfiguration upgrade to later.
• May need more than 2 weeks -- ATC is not critical to solar switch-off.

• Successfully commissioned. Currently in use to control ngamai operational sms suites.
• Twister is still the operational-development server with similar s/w to nmoc-sms
  • Contact Milton if CACWR wants the latest NMOC sms setup

• Continue regular reminder to users re their migration.

• Work getting UMUI jobs on ngamai to work is being done as required.

  • UM versions being addressed include vn7.5, vn7.8, vn7.9, vn8.2 and vn8.4.
  • potentially, each version may need a build job and a run job for both ngamai and raijin, totalling 20 different jobs (4x5).
  • Not all have been done. Development work will be done based on user needs.

• Research porting being supported, but need to temper user expectations to limitations of IT resources.

• Change of group name "access" to "access.admin" on ngamai to make it the same as at NCI.

  • No problem expected as gid (group-id) will remain the same.
  • Need to coordinate when to do it.

• Work to get Rose and Cylc available on ngamai being done by Robin and Wenming.

• Work in progress. Wenming following up with Martin.

• Identify staff to work on Raijin version.

• Further work on build documentation page ( https://trac.nci.org.au/trac/access/wiki/Access_NWP_Build_Procedures ) desired
  • Add build documentation of small execs
• For now only Joan is available from NMOC to test out the builds - will not happen until after ngamai is fully operational.

• Porting of AGREPS development ensemble suite to ngamai.

  • work-in-progress (azs,mjn,David Smith).
  • Global Forecast suite now running on ngamai and raijin.
  • Global Pertubation suite having problem with ops steps. Xiao helping.
  • Will add documentation of AGREPS executables to "Build Documentation" page (azs).

• Porting of APS2 to ngamai.

  • work-in-progress (Xiao).
  • APS-2 already runs on raijin although it is behind real time.

• Research APS-1 on ngamai.

• Running of full suite is not required.

• Only run component as needed. Capability for this is already available.
