We focus on efficient implementation of the recurrent deep-learning model as implemented in Amun, the fast inference engine for neural machine translation. We improve the performance with an efficient mini-batching algorithm, and by fusing the softmax operation with the k-best extraction algorithm. Submissions using Amun were first, second and third fastest in the GPU efficiency track. %R 10.18653/v1/W18-2714 %U https://aclanthology.org/W18-2714 %U https://doi.org/10.18653/v1/W18-2714 %P 116-121
