PyTorch Introduces FBTriton Kernels to Speed Table Batched Embedding Operations

PyTorch's blog describes a Triton-based implementation of Table Batched Embedding (TBE) forward and backward kernels for recommendation-system embedding lookups, which the post says outperforms legacy CUDA kernels on these workloads.

On B200, an updated CUDA bounds-check step reaches up to 1.24x speedup on that component, and an optional forward-side preprocessing path cuts combined latency from 79.537 ms to 66.183 ms (−16.8%) on a large configuration.
