the tree that keeps giving.. could be interesting to see whether some NCCL env variable can bring some speed back from broadcast, could be why this tanked ?

Sure, but does it explain why there was a regression? I was thinking the NCCL_MAX_NRINGS would possibly increase the performance but would not explain why it dropped.

I'm guessing that NCCL is statically linked (so part of the pytorch-cu release) and could be that it defaults changed when changing pytorch versions ? just a guess, could well be wrong
