Render lops through pdg? Jan. 23, 2020, 9:53 p.m.

time passes…

Ok, the license server was out out date, got that fixed. Making progress, but it's difficult. Getting lops to render from pdg locally is mostly ok, getting it to work through tractor is about 50% success. Even locally about 10% of the submissions will fail for whatever reason, resubmit an identical job and it's fine.

Will try and make some repros, but it all feels worryingly delicate atm.

Tried that example locally with latest daily build (18.0.357), getting that error that seems to have plagued a few people, karma thinks it can't find a licence. The top error:

Any chance this is assuming our university education licenses are apprentice licences? I recall having a similar problem with pdg several months ago. I've asked our IT guy to check the license server is the H18 version, not the old H17.5 one, will find out shortly…

Our clever folk got tractor and pdg working again (more firewall esoterica), I was keen to try rendering a lop graph on the farm with pdg.

How does one do this?

Couldn't see a lop fetch or karma top, trying a rop fetch that pointed to a karma lop errored. I assume I'm missing something obvious!
