Compiler-first duality enables portable O(1) Mamba-2 inference

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method for optimizing Mamba-2 inference, focusing on compiler-first state space duality. This approach enables portable autoregressive caching with $O(1)$ complexity, eliminating the need for custom CUDA or Triton kernels. The resulting single-source inference path, implemented in JAX, demonstrates significant speedups on Google Cloud TPUs and NVIDIA GPUs, achieving high hardware utilization and matching reference perplexity scores.

    Compiler-First State Space Duality and Portable $O(1)$ Autoregressive Caching for Inference

    arXiv:2603.09555v2 Announce Type: replace-cross Abstract: High-throughput Mamba-2 inference is usually tied to fused CUDA and Triton kernels, limiting portability across accelerator backends. We show that the state space duality (SSD) recurrence has a compiler-friendly structure:…
