The cuDNN "Fused Flash Attention" backend was landed fortorch.nn.functional.scaled_dot_product_attention. On NVIDIA H100 GPUs this can provide up to 75% speed-up over FlashAttentionV2. This speedup is enabled by default for all users of SDPA on H100 or newer GPUs. [Beta]torch.compileregi...
>>> UserWarning: Single-Process Multi-GPU is not the recommended mode for DDP. In this mode, each DDP instance operates on multiple devices and creates multiple module replicas within one process. The overhead of scatter/gather and GIL contention in every forward pass can slow down training. ...
