NKI
A low-level programming interface provided by AWS for its Trainium and Inferentia chip series, analogous to CUDA for NVIDIA GPUs. It allows developers to bypass high-level framework abstractions and write low-level kernel code directly to maximize chip performance.
Timeline (last 90 days)
The team leveraged the Neuron Kernel Interface (NKI) to reconstruct the critical computation paths for real-time video generation at the kernel level.
NKI (Neuron Kernel Interface) is AWS's low-level kernel programming interface for Trainium and Inferentia chips, allowing kernel functions that execute directly on hardware tensor engines to be written in Python syntax, with manual control over data movement between SRAM and HBM.
Standard CUDA optimization experience cannot be directly ported to Trainium and requires re-adaptation through low-level interfaces such as NKI.
Compared to high-level frameworks, NKI's trade-off is a steeper development curve, with the benefit of execution efficiency close to the hardware's theoretical peak.
