Describe
In the new communication library, we designed ProcessGroup to manage different communication group. Inside each process_group has its own stream which all communications in this group will be done on this stream. For high level API, like
distributed.all_reduce, we useuse_calc_streamto indicate whether this operation is sync or not. Notice that frequently add unnecessary cuda events may lead to low performance on some model. In order to achieve high performance, this pr add a new API name distributed.stream.all_reduce. This new API provideduse_calc_streamandsync_opboth.sync_op, indicate whether communication is sync or not.use_calc_stream, do communicate on calc stream, save the time of switching stream. Only work whensync_opis true.
