+* Enable fused QKV transposition by switching the heads and time dimensions before the QKV split
+* Cache the prepared source lengths mask in the Transformer decoder state and reuse it in the next decoding steps
+* Pad the output layer to enable Tensor Cores only once instead of updating the layer on each batch
+* Vectorize copy in Concat and Split ops on GPU
+* Factorize all OpenMP parallel for loops to call the `parallel_for` function
