Rendering Animation following Version II of the Doc Chaosgroup : Place of the spawners?

Hello there,
I follow this tutorial (see link below) to render animation with moving camera or(and) moving objects,
but the question is (not explained in the tutorial) when can i use the spawners of my renderfarm in the workflow (May i use the spawners calculating the IR ?)

Chaos Docs

Thanks in advance for helps !
Best regards !

I think IR still has to be calculated on a single machine, when you are done then you can distribute.
I haven’t done any of that workflow in a long time now I rather render brute force light cache instead, is so much simple and no worries of saving files or overwriting files.
