New algorithm accelerates long-context transformers with relative-position attention

Researchers have developed a new algorithm that significantly speeds up and reduces memory usage for transformers handling long contexts, particularly those using relative-position attention mechanisms. This method integrates additive relative-position terms into FlashAttention-style computation through offset-aware tiling and product reuse. The approach demonstrates substantial performance gains, achieving up to 6.4x faster forward passes and 21x faster backward passes for 8K-token sequences, with notable reductions in memory consumption.

IMPACT This research could enable more efficient processing of longer sequences in transformer models, benefiting applications like speech transcription and other long-context tasks.
