Hey Ke,
We do not recommend disabling flush using the environment variable OFI_NCCL_GDR_FLUSH_DISABLE if you are using EFA libfabric provider (therefore, there is no point comparing performance). The configuration is provided for the libfabric networks that can guarantee data arrival at GPUs with network completions.
Hope that helps.
