llama.cpp first loads the model into memory and then copies it from memory to VRAM, which stems from the operating system's memory-mapped (mmap) mechanism.

Unverifiedllama.cpp通过mmap机制将部分权重映射到内存/磁盘，但调度策略对模型结构不知情，无法做出智能预取决策80% similarUnverifiedThe llama.cpp project has made local inference of quantized models possible on various hardware, while MLC-LLM focuses on compilation optimization for mobile devices.66% similarUnverifiedThe available memory and VRAM of a local model directly determine the obtainable context window length, because inference requires maintaining a KV Cache in VRAM.65% similarUnverifiedLLM自回归解码阶段每生成一个token都需从显存加载全量模型权重，批量较小时形成内存墙65% similarUnverifiedThe memory of LLMs depends on the context window, which is the maximum number of tokens the model can process in a single inference.65% similar
