Motivation
This PR adds support for inference on non-MoE IBM Granite 3.x models (see https://huggingface.co/collections/ibm-granite/granite-30-language-models-66fdb59bbb54785c3512114f).
Granite 3.0's architecture is similar to that of Llama 2 and 3, but with additional multiplier parameters for improved numerical stability through Maximal Update Parameterization.
Modifications
LogitsProcessorfrom vLLM 0.4. This change add an optional logits multiplier parameter. Granite models use this multiplier to implement Maximal Update Parameterization.granite-3-instructfamilyChecklist
