Nice! Does DistributedDataParallel work also? |
Not yet, work in progress. A few tricky things and more C++ code than I'd like, but close to something running, just need to get a basic multiprocess gather/scatter/reduce with tiny tensors. |

Issue narrowed down to torch backend not supporting views for out or dest tensors. Working on fix. |
