NOTES from second porting Meeting, Wed 11am, 17th July 9E Meeting room.
Present: Ivor, mjn, Joan, ttl, ilia, Wen Ming, Zhihong, Xiao, Mdix, ciwt, azs, rab
Configuration Management of systems/suites that go into operation
- There was a discussion on rationalising the directory structure of operational systems and using SVN to keep track of changes as well as thorough documentation of all components.
- -- This aim is generally agreeable to all present although there are differences in priorities, and on the best way to proceed.
- -- It was noted that this subject extend beyond the scope of "porting" although there are arguments that its implementation (at least some of it, eg. using SVN) may aid in the porting work itself.
- -- This subject is also potentially vast.
- -- Failure to implement some kind of source control at the very beginning will result with hard to maintain system, detrimental in the long term.
- -- Need to be able to trace (and rebuild) source of executables.
A round table discussion was initiated to give everyone present chance to present their issues. Many of the issues relate to Source/Config management above. Other issues raised are noted in items of the table below
Issues and Task List updated as discussed during meeting. Some issues migrated to omit list table at the bottom.

30 Days Ngamai Acceptance test |
Commenced from handover date (end June), running a SSP mix of programs (including UM benchmark from solar. Acceptance mainly upon 30 days of running without error. No acceptance test doc. Due to complete on 4th week of July. So far there have been no problems. Side note: So far Raijin have been found to be slower than solar for UM using equivalent number of cores/config |

Setup and rebuild of /apps |
So far < 50% have been done, but the main ones crucial for porting such as compilers have been done. Ongoing work. |

Intel compiler 11.0.83 |
Strong need, but not straightforward to provide. This may be a difficult issue. Two prong approach is advised. Attempt to use LD_LIBRARY_PATH to tackled this so far failed due to what appear as hardcoded path within the intel 11.0.83 setups. Consultation with various local experts and intel staff so far is unsuccesfull. In the meantime recompilation with v12 have shown very small difference which may be acceptable (Ilia & Xiao). Do not use -Xhost option. Do not use Intel v13 compilers. |

Source Code for SURF |
Migrate SVN repository from solar - cut over during 1st weekend of October. In general, all svn repository will be moved to NCI to allow access from raijin. |
azs |
| 11 |
~access directory |
Copy solar's to "from_solar" on ngamai. Move to proper place as we go along. Improve where suitable. Interoperability with raijin is important consideration and should be done where possible. |

GCOM Libraries |
Decide naming strategy, identify required versions/compile options, Synchronise with Raijin |

fcm utility |
Only fcm2.3 should be required as fcm is backward compatible. fcm 1.5 have been used succssfully on yambuk. Need certain Perl Libraries. |
Martin |
| 22 |
Miscellaneous utilities used by ACCESS systems |
Comment |
UM Porting group, azs |
| 23 |
profile.gen.access |
Should be in /access/scripts, not in /access |
Xiao |
| 24 |
UM Ancillaries input data. |
Since UM ancillaries, in particular for N512 can be quite large, propose that it go into /access/ancils instead of into UMDIR. |
access.admin, azs |
| 25 |
Misc UM parameter files |
A few smallish radiation param, verts, ancil and STASHmasters etc. |

APS1 suite |
To expand this into more detailed list |
Joan, ciwt, Xiao |
| 27 |
APS2 suite |
APS2 is of secondary importance since it is not operational yet. |
ciwt, Xiao, Sergei, Joan |
| 28 |
ACCESS systems/suites not synchronous with operational system |
Will not be able to address this as part of porting project. Will need to wait until APS3 ROSE based systems. In the meantime, better documentation will help, also better source code tracking/building procedure - See discussion at start of this note. |

NCI Training course on 22nd July |
There are sessions for new users as well as experienced users. |

| 31 |
Back copy of solar files prior to its decommisioning. |
Easy to do. |
Porting Group |
| 32 |
$CWSHARE |
Will still be required, though most shared scripts and utilities will be in /access/bin or /access/scripts. |
Porting Group |
| 34 |
Higher management's Porting plan. |
Will be of help for our reference. There is also call for detailed estimates of resources required |
rab, mjn |
| 35 |
SMS |
To be installed as a "module", as part of /apps. - Will be modularised. - Use new NMOC included files from Milton Woods, but CAWCR research may stay with their own set of include files. - put "SMSOUT" into different directory |
/apps group, Wen Ming |
| 36 |
Veri Py |
Part of some SMS suites. New version to be developed for Raijin |
mjn, Wen Ming |
| 37 |
Plotting Systems |
Part of some SMS suites. New version to be developed for Raijin |
mjn, Wen Ming |
POINTS/ISSUES THAT CAN BE OMITTED FROM FUTURE NOTES
| 1 |
Oracle Handover of Ngamai to BoM |
Done on 27th June |
rab |
| 4 |
Ngamai Configuration |
Linux 6.2 Will be identical to solar, but with newer s/w versions. Generally, for all s/w on solar, there will be equivalent on ngamai, but no older version unless necessary. File system setup is similar, different h/w namespaces. There will be filesystem quota. |
rab |
| 29 |
STASHMaster File Regression |
Not possible. Must be due to misunderstanding/mistake |
Porting Group |
| 33 |
Suites/Applications to work regardless of user's default login shell and environment |
Desirable. |
Porting group, all developers. |
Next Meeting is on Wed 11am, 24th July 9E Meeting room.
