Support ParallelFor pipeline features for each operation. Set
parallel_count > 2to start parallel operations like distributed training, distributed data processing etc. Below are features/limitations:TF_CONFIGfor Tensorflow andMASTER_ADDR,MASTER_PORTfor Pytorch. Yet in some cases, workers rank >=1 should wait for rank0 to start. This can be achieved by waiting rank0's TCP server port by user.How was this pull request tested?
Unit tests are included in
test_bootstrapper.pyto ensure argumentparallel_countis working.TODO:
