has NEMO3.4 been installed on the XCM?

Reported by: till Owned by: annette
Component: NEMO/CICE Keywords: xcml00, coupled
Cc: Platform: MONSooN
UM Version: 8.6

Description

Dear CMS Team,
I am migrating my UKESM experiments from the old MONSooN to the XCM. Trial with N96 AMIP is ongoing (xltwa).
My question is: has NEMO3.4 been installed already on the XCM? If so, I could use it for my coupled N96-ORCA1 jobs (example: xllfk).
Thank you!

Hi Till,

Karthee has run a coupled UM 8.6 - NEMO 3.4 job on xcm. This is N96-ORCA025 but you should be able to copy the NEMO/CICE and OASIS configurations. The job id is xlsdd.

There is a bit of an issue with the UMUI for the coupled model at this version. We are working on this, but in the meantime a couple of hacks are required (see below).

Do let us know if you have any issues with this.

Annette

From Karthee (cc'ed)

Please refer to /projects/umadmin/ksival/um/xlsdd/umatmos/cfg/bld.cfg file for exact entries.

  1. The following entry is to be added to the bld.cfg file of umatmos.
    tool::fflags::UM::control::coupling                    -O2 -Ovector1 -s default64 -em -J. -hfp0 -hflex_mp=strict -I/projects/umadmin/ksival/gcom/cce/gcom4.7/xc40_cce_mpp/build/include  -INetCDFmodule  -I$(UMDIR)/grib_api/cce-8.3.4/1.13.0/include -h noomp -I/projects/umadmin/ksival/oasis/oasis3_3/20110919_para_MxSeg1500/prism/crayxc40_cce/build/lib/mpp_io -I/projects/umadmin/ksival/oasis/oasis3_3/20110919_para_MxSeg1500/prism/crayxc40_cce/build/lib/psmile.MPI1 -I/projects/umadmin/ksival/oasis/oasis3_3/20110919_para_MxSeg1500/prism/crayxc40_cce/build/lib/oasis3.MPI1
    
  1. the entry C98_1A=c98_1a should be modified to C98_0A=c98_0a in
    • tool::cppkeys and
    • tool::fppkeys

Hi Annette,
thanks a lot for that, this look promising!

However the job (I copied it to XLTWB) does not compile yet I'm afraid. This is the error message in the .leave file:

ERROR: /projects/ukesm/tkuhlb/um/xltwb/umatmos/cfg/bld.cfg: LINE 50:
       tool::fflags::UM::control::coupling::oasis3_atmos_init: invalid sub-package in declaration.

The thing is this: I applied the hack from Karthee to this file, but when I resubmit the job, everything is extracted from anew and the hack is overwritten. I guess that is the problem? It would be great if you could look into this.

Hi Till,

Edit the file again, then instead of re-submitting from the UMUI which will cause the cfg files to be ovewritten, just manually re-submit from the umui_runs directory.

  • Cd to ~/umui_runs on MONSooN.
  • Find the latest directory for this job-id through ls -alrt.
  • Cd into that directory.
  • Run qsub stage_1_submit.

Hi Annette,
thank you for that. The compilation job now runs much longer (approx. 12 min), but eventually still fails I'm afraid. (XLTWB on the XCM.) The main reason appears to be:

ftn-855 crayftn: ERROR IOS_INIT, File = ../../../../../projects/ukesm/tkuhlb/um/xltwb/umatmos/ppsrc/UM/io_serv
ices/server/ios_init.f90, Line = 16, Column = 8 
  The compiler has detected errors in module "IOS_INIT".  No module information file will be created for this 
module.

The .comp.leave file is here: /home/tkuhlb/output/xltwb000.xltwb.d15253.t132900.comp.leave

I admit that I had to tinker with the bld.cfg file a little more than explained above. Intially it had a few lines starting with tool::fflags::UM::control::coupling::oasis3 which I had to remove in order to make the compilation job work at all. There's still some differences to Karthee's file named above, e.g. whether this line:
tool::cflags -O2 -g -std=c99 -h omp
has omp or noomp at the end.

Thank you for your help!

Hi Till,

I think you may need to have OpenMP switched off - so change the -h omp to -h noomp wherever it appears. (We thought you might get away without changing this.)

Till,

The compile issue with the IO server code and OpenMP has been fixed (hack number 2 mentioned above). We have updated the central configuration files so this should be picked up by your jobs automatically when you submit a compile job.

I will update you about hack number 1 shortly.

  • Keywords xcml00, coupled added; xcml00 removed
  • Resolution set to fixed
  • Status changed from assigned to closed

I think that the OASIS paths have now been fixed properly in the config files as well. If you have any further issues, obviously do get back in touch.
