New Systolic Linear Attention Layer Boosts TPU Performance

By PulseAugur Editorial · [1 sources] ·

Researchers have developed Systolic Linear Attention (SLA), a new attention layer optimized for Google TPUs. Unlike existing gated delta attention layers tuned for GPUs, SLA is designed to leverage the wide systolic matrix units of TPUs, improving efficiency by utilizing more of the matrix tile and reducing bottlenecks. This optimization leads to significant speedups, with SLA layers running 1.6x to 2.5x faster than existing KDA kernels on TPU v7x. AI

IMPACT This optimization could lead to faster training times and more efficient deployment of large language models on Google's TPU infrastructure.

    Systolic Linear Attention: Co-Designing Tile-Grouped Gated Delta Attention for TPUs

    arXiv:2611.06828v1 Announce Type: new Abstract: Gated-delta linear attention layers such as Gated DeltaNet (GDN), Kimi Delta Attention (KDA), and GDN-2 are tuned for GPUs, where small tensor-core tiles and fast vector registers make per-channel decay rescaling and sequential in-b…
