use more than 3 digits for outputnnn and restartnnn?

[aekiss]

The output and restart directories are distinguished by a 3-digit run number, but we are getting uncomfortably close to running out of digits in the long 0.1 deg ACCESS-OM2 runs (we would run out of digits after 250 years at 3mo/submit). So I'm wondering how hard-coded that is, and whether it could easily be increased?

[aekiss]

e.g. @AndyHoggANU's run /g/data/ik11/outputs/access-om2-01/01deg_jra55v13_ryf9091 is up to output688 so far...

Has anyone actually tried this before? I recall it will output more digits if needed, it will just lack the padding.

>>> counter = 1000
>>> restart_dir = 'restart{0:03}'.format(counter)
>>> print(restart_dir)
restart1000

[aekiss]

Some workflows I've created rely on alphabetic sorting, so the lack of zero-padding would be a problem for that.

But if payu is adjusted to use 4 digits it would need to initially be optional so it doesn't mess up the naming in existing runs.

Maybe it's not worth worrying about, since we are yet to even exceed this 3-digit limit?

[marshallward]

It should be a quick job to replace the hard-coded 3 with a variable whose default value is 3.

[marshallward]

Another solution is to allow the user to define their own format string, with 0:03 being the default (or even restart{0:03} depending on how ambitious we are feeling...)

I noticed Adele had a run with run numbers > 999 and it seemed to work fine apart from ls not sorting correctly without using an option like -v or -t
