Removing tracers from stash/ removing updates

Reported by: vegan Owned by: um_support
Component: UM Model Keywords: HadCM3
Cc: Platform: ARCHER
UM Version: 4.5


I'm running into problems taking a working job (xmzh.a) computing with isotope tracers and stripping out tracers in order to run the same model version with (slow) and without (faster) tracers.

  • The original job compiles and runs fine on Archer (xmzh.b).
  • Next I removed isotopes from the stash (retaining 72 of 83 elements in Atm., and 20/35 in Ocean), and removed the previously used "USER-stashmaster file" relating to isotopes (atm&ocean). This is (xmzh.c), which compiles but doesn't run "wrong levels in STASH master"
  • Next I removed the mods l. 76, 75,73,72, 70, and 68-62 (isotope-related) in "Modifications for the model" (xmzh.d). This job, again, compiles fine but falls over when run. It does complain about some STASH things?
  • (xmzh.e) is an attempt to start the model with a start dump that does not contain the tracers. Complaints are relating to wrong levels in prestash.

What am I overlooking? Do I need to replace the user stash file with dummy values?

Hi Kira,

Sorry for not responding to this. Are you still having problems with this?

Hi Ros,
yes. I've removed everything (to my eye) that is non-standard HadCM3 (in the mods), but the model crashes when I try to run it.

Hi Kira,

I tried to build and run xmzhc, but some files are missing

cp: cannot stat `/n02/n02/vegan/um_updates/DEUTERIUM_NOV13/adv_noqpos.f': No such file or directory

There needs to be a /work in front of this, but the um_updates directory is missing.
