old dgx with 8x32 v100 gpus support

[ninjadude333]

hi , i have an old dgx with 8x32 gb ram v100 tesla gpus sm70, compute 7. can i use multi gpus to run a single wan2.2 or ltx2 job, to avoid ooms or speed up things. i dont talk about 2 ibstance running in paralal on different job, im talking about getting more value on a single workflow job run.
i heared ltx2 has native multi gpu support, not sure how to activate it, or what itll will do.
any ideas?
