WebAbstract. We isolated mutations in Drosophila E2F and DP that affect chorion gene amplification and ORC2 localization in the follicle cells. In the follicle cells of the ovary, the ORC2 protein is localized throughout the follicle cell nuclei when they are undergoing polyploid genomic replication, and its levels appear constant in both S and G ... WebMay 8, 2024 · In this case I assume you are using DistributedDataParallel (DDP)? DDP calls allreduce internally. If the first process is also in the same process group but is not running backward on DDP model, other processes would hang on backward, because they need 1st process to join the allreduce.

In our view, DDP is a better option. WebDDP requires Reducer instances on all processes to invoke allreduce in exactly the same order, which is done by always running allreduce in the bucket index order instead of actual bucket ready order.
