Worked on the aws-neuron/aws-neuron-sdk repository to enhance developer experience by updating and refining documentation related to Neuron Core (LNC) mappings for Trn2 instances. Focused on improving configuration accuracy, the work involved clarifying the mapping between physical and logical Neuron Cores and renaming configuration fields to better reflect their purpose. Adjustments were made to the descriptions of key parameters, such as neuroncore_version, to align with evolving LNC configurations. The updates were implemented using reStructuredText (rst) and documentation best practices, ensuring that the SDK documentation remains clear, accurate, and aligned with recent changes in Neuron Core configuration management.
