kern-llm
kern runs a model as a manifest: a typed declaration of buffers, states, ops and programs, compiled kernels, and weights. This package is kern for Python:
kern: the runtime binding (kern.Runtime), the readers of a manifest's host contract (kern.host) and the rank group overtorch.distributed(kern.group);kern_vllm: a vLLM plugin that runs a manifest as the model;kern_sglang: the same for SGLang.

Linux x86_64 and aarch64, Python 3.10 or newer. The runtime loads the NVIDIA driver (CUDA 13, r580 or
newer) and cuBLAS 13 when it first runs; torch comes from the engine. The plugins do nothing unless
KERN_MANIFEST is set. Guides: vLLM,
SGLang.
