Force python scripts to run on the farm

If you have a python script node, even if you have a tractor or deadline scheduler, it will run in your local houdini session by default.

To fix this, turn off 'Evaluate in process'.

Ensure a rop geometry top sim runs on a single blade

You don't want 240 machines all doing their own run up, that's silly. Go to the 'rop fetch' tab, enable 'all frames in one batch', that'll lock it to a single blade and run sequentially.

Tractor scheduler stuck

Happens too often. Tricks to unstick it in order of least to most annoying:

  • Make sure there's no active stuck jobs of yours on the farm, delete 'em all and try again
  • R.click on tractor scheduler, 'delete temp directory'
  • Select the tractor scheduler, ctrl-x to cut it, ctrl-v to paste it
  • Reload the hip
  • Restart houdini

Rez and tops debugging

Running this in a python script top to see whats going on with rez and environment values:

print('debug info...')
print ('')
import pdg
has_tractor = str(pdg.types.schedulers.has_tractor)
print('pdg.types.schedulers.has_tractor: ' + has_tractor)
print ('')
