Technical solutions for massive code processing

The following strategies can be adopted for analyzing the code base at the GB level:

  • Enabling YaRN extensions: Expand context window from 256K to 1M tokens, modify startup parameters-c 1000000
  • slice-and-dice processing technology::
    - utilizationqwen split-by-modulesCommand to split code base by functional module
    - Summarize the results after analyzing each module individually
  • Mixed-precision inference: Add at Ollama deployment--gpu --precision fp16Parameters to reduce video memory usage
  • Disk Cache Mechanism: Configurationexport QWEN_DISK_CACHE=/path/to/cacheAllow partial intermediate results to be written to disk
  • tiered loading strategy: By.gitignorePattern filtering of non-core code such as test files

Recommended Hardware Configuration:
- Handles 1M contexts: A100/A800 graphics cards with at least 80GB of video memory
- 256K context: 24GB video memory RTX 4090 is up to the task
- CPU-only mode: requires 128GB or more of RAM and avx512 instruction set support
