      feat(dynamo-run): Allow setting KV cache block size (#1175) · 183f2b32
      Graham King authored
      Example:
      ```
      dynamo-run out=<engine> <model> --kv-cache-block-size 64
      ```
      
      In a distributed system this goes on the worker node and is propagated to ingress via the model deployment card.
      
      Previously hard coded to 16, which is now the default.
      
      - Load context_length from model. Closes #1172
      - Store context length and KV cache block size in Model Deployment Card #1170

      feat(dynamo-run): Allow setting context-length (#1157) · 6d5da821
      Graham King authored
      Llama 4 has a very large context length (aka n_ctx, model_max_length, max_model_len), and vllm won't start unless it can allocate enough KV cache for the entire context.
      
      Allow passing `--context-length <N>` to `dynamo-run` to limit it so long-context models will fit.
      
      Future todo:
      - Restrict every request's `max_tokens` to below the context length. Our pre-processor should do this by setting stop_conditions.max_tokens. mistralrs engine wrapper must do it itself because it does not use the pre-processor.
      - mistralrs and llamacpp currently have a hard-coded max context length if one is not provided on the command line. Change those to be the model's built-in max, read from the GGUF or tokenizer_config.json.

      feat: Support multiple models on single ingress node (#1127) · aeb79e62
      Graham King authored
      We can now do this:
      
      - Node 1:
      
      ```
      dynamo-run in=http out=dyn
      ```
      
      - Node 2 and 3, two instances of component 'backend' in the nemotron_ultra pipeline:
      
      ```
      dynamo-run in=dyn://nemotron_ultra.backend.generate out=vllm /data/models/NemotronUltra
      ```
      
      - Node 4 and 5, two instances of the 'backend' component in nemotron_super pipeline:
      
      ```
      dynamo-run in=dyn://nemotron_super.backend.generate out=vllm /data/models/NemotronSuper
      ```
      
      The ingress node will discover all four instances and route correctly. We have been planning for this for a long time now.
      
      As part of this auto-discovery is now always `out=dyn`, with no extra URL parts. Previously it could only route to a single pipeline.
      
      Also:
      - Refactor endpoint / instance naming now that I understand them
      - Fix removing models when their instance stops.
