Wall time exceeded error in recon job

[amenon]

Hi CMS,

This is a continuation of the ticket #2428. The reconfiguration job in u-ay368 (which is a copy of the suite u-av692 in ticket #2428, but with Andy Malcom's optimisation branch switched off) is still failing with the following error:

????????????????????????????????????????????????????????????????????????????????

Switching off the optimisation branch was a test I did to get over this error, but with no luck. Earlier, I also tried by increasing the processors to 22X12 as Willie suggested. But that too didn't work. Could you please advise on any possible solutions for this?

Many thanks

Please set

RCF_PRINTSTATUS to "Extra diagnostic messages", and add

ATP_ENABLED = 1

to
[runtime]

root?

[environment?

ATP_ENABLED = 1

reduce the wallclock to say 10 mins & try again

Hi Arathy,

The problem is in the INCOMPASS_km4p4_RA1T_um_recon task. Although it has 'run' for three hours absolutely nothing has been written out. This could be a problem with the dump that it is trying to reconfigure. I can't see where that file is, could you let me know.

Regards
Willie

[willie]

OK, just found it in the RECONA file. I had a look and the dump is NaN free and readable in xconv.

Willie

[willie]

The ancillary files listed in the SHARED file are also NaN free. I notice that the RA1T_astart file in /work/n02/n02/amenon/cylc-run/u-ay368/share/cycle/20160701T0000Z/INCOMPASS/km4p4/RA1T/ics has zero length.

Willie

[willie]

OK, In SHARED we have, in the name list recon_technical,

ainitial='/work/n02/n02/amenon/cylc-run/u-ay368/share/cycle/20160701T0000Z/glm/ics/glm_astart'

and in RECONA, we have

astart='/work/n02/n02/amenon/cylc-run/u-ay368/share/cycle/20160701T0000Z/INCOMPASS/km4p4/RA1T/ics/RA1T_astart'

and this is a zero length file. So something is wrong here.

Willie

[willie]

The model is

$AINITIAL —> Reconfig exec —> $ASTART

so this shows it started to write the output dump and then hung.

In the um app, go to IO System Settings → Print Manager control and switch on pmt_force_flush.

In um → env → Runtime Controls → Atmosphere only, set PRINT STATUS to extra diagnostics messages.

Do this in addition to Grenville's changes and then run again.

Regards
Willie

Thanks a lot Willie and Grenville. I was in Bristol for a training yesterday. I will try these and will get back to you soon.

[amenon]

Hi,
I made the above changes. It failed with the following description:
atpFrontend.exe: main: Build of MRNet network failed 'MRNet: Network failure'

It appears that you ancillary data (land-sea mask etc) is not on the same rotated grid as your RA1T domain. You probably need to regenerate the ancil files of the (20, -75) rotated pole. {they are currently on (90,180))

Hi Arathy

Pl let us know if Stu's suggestions worked - we'll delve into the reconfig in the meantime.
