Hi, no it’s really not late. After implementing my model using parameter server as well as rpc batch update, but unfortunately with no particular execution time improvement compared to single node hogwild, I think I kinda got the feeling on how to work with pytorch distributed for my use-case. Do you have any other resources for using the functions other than Distributed communication package - torch.distributed — PyTorch 1.9.0 documentation 1 ? Btw, thank you so much for mentioning the c10d, I almost forgot about that because it was too complicated for me when I first read it when I was just learning pytorch distributed.
