AWS–Reactor: hardware-tuned streaming video inference on Trainium

What changed

Optimized a Rolling Forcing streaming pipeline with NKI kernels for3D rotary embeddings and cache copies, fused attention transposes, hybrid head/sequence sharding and batching of common denoise/cache-update work.

Scientific scope

Optimized a Rolling Forcing streaming pipeline with NKI kernels for3D rotary embeddings and cache copies, fused attention transposes, hybrid head/sequence sharding and batching of common denoise/cache-update work. Company technical account supports the integration, not a new Rolling Forcing algorithm, invention of NKI/parallelism or independently certified real-time performance. Kernel latency and full-pipeline frame rate are different metrics; reported single-chip results depend on model, resolution and configuration. Article writer Stephen Zorio is not asserted to be a complete technical-inventor list; corporate project groups retained.
