3 Setup and rebuild of /apps Ongoing work. sms and python almost done. perl which is required for fcm2.3 to be done. fcm1.5 works with std perl.
ACTION: Monitor Status.
/apps, rab
6 Intel compiler 11.0.83 * Details moved to NewSun_IntelCompiler_11.0.83
* Re-download & rebuild of v11 will be attempted by Tim Pugh and Justin Freeman. If successful, will be compatible with openMPI, will not need MPI/Sun.
* Questions: Will single executable built with identical compiler options, using non-machine specific setting, identical compiler version, openMPI library instead of MPI/Sun, give bit identical result on raijin-ngamai-solar.
* OpenMPI1.6.3/5 at NCI is built using GNU compiler. At BoM, Intel Compiler was used - what is the impact?

* Robin update: info from Tim Pugh; Justin to try doing this, but he's currently on leave for 2 weeks.
* Importance of this as a fall-back if there are problems with v12 execs was again emphasised.

ACTION: Continue investigations.

7 Source Code for UM No action required. Original repository already in access-svn. azs
8/9/10 Source Code for VAR,OPS,SURF In general, migrate all SVN repositories from solar early October 2013. Use accessdev if it is ready. Otherwise migrate to ngamai first (without access from nci). Ask for increase in diskspace for access-svn.
ACTION: Prepare for migration. Monitor reliability of access-svn server.

11 ~access directory Goal of having interoperability with raijin is not straightforward, particularly with executable and libraries. Need to handle case by case. $HOST or $MACH subdirectory required in some instances. Also see Scott's tildeAccess notes.
ACTION: Address case by case as ~access is being setup. Investigate transfer speed solar-ngamai.
access.admin
12 GCOM Libraries Updated path/name: example: ~access/apps/gcom/GCOM3.5/ngamai/bld_12.1.8.273_1.6.5_new_optns-03.
ACTION: Information on building gcom to be documented on the wiki.

13 Migrate Trac databases Cutover from solar to ngamai 1st weekend of Oct.
ACTION: Prepare migration plan.

14 UM Small execs Do for vn7.3, 7.5, 7.6, 8.2 and 8.4. May be able to use copy from raijin.
ACTION: No report.

15 Migrate UMUI, VARUI, OPSUI and SCSUI Initially to operate UMUI from solar. Big Font issue encountered on ngamai. umuix which uses ghui3.0 does not have the problem, but it is desired that both ghui2.0 and ghui3.0 to work before migrating.
ACTION: Workaround exists, but the earlier the migration the better.
azs, zhihong, ilia, xiao, say
16 CAP program on ngamai vn8.1 now available and set up on Raijin. Sufficient for time being; not urgent to port to ngamai, as we can create ancils on raijin and copy to ngamai.
ACTION: No action required.

17 Re-compile/build UM 7.5/7.6 Executables for APS1 - Global, Regional, Access-C ... * Documentation of build procedure, UI job id, wiki page of build or similar to UKMO Parallel suite page.
* Sample of build documention to be created for discussion.
* EXAMPLE FOR REF, see UKMO Parallel Suites documentation on collab wiki.
ACTION: Detailed documentation for each build should be available on wiki.

* Zhian's mods also included.
* Working on producing documented build procedure.

* See AccessGBuild for more details.
ilia,xiao,azs
--17b ACCESS-R/R12 * VN7.6 (PS25)

ACTION: Monitor status.

21 fcm utility fcm 1.5 used succssfully, but not fcm 2.3. fcm2.3 will need perl with appropriate libraries from /apps. See 3.
ACTION: Monitor status.
martin, /apps
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 (or into /access/data/ancils).
ACTION: No update.
access.admin,azs
26 APS1 suites * Xiao has working ngamai AG1 NWP suite based on NMOC SCS components; using v12 UM/VAR/OPS executables from 17. Has successfully run 2 cycles from 21 July. Results are different from solar, based on residuals in first VAR step; don't have convenient diagnostic for OPS step. Concerned that VAR residual differences are bit larger than expected.
* Planning to start one-month test .

ACTION: Chris/Xiao/Zhihong to look at OPS/VAR component assessments.
xiao,joan
27 APS2 suite APS2 porting is of secondary importance since it is not operational yet.
ACTION: None for now.
