Researchers have developed mzCache, an on-device LLM inference system designed to manage memory effectively in multitasking mobile environments. This system addresses the issue of memory eviction by the operating system during app switching, which typically leads to slow restoration or recomputation. mzCache partitions LLM memory into fine-grained shared buffers, allowing for partial eviction and restoration with concurrent cross-processor access, and utilizes hybrid swap and backward-out eviction policies for low-latency restoration. Implemented as an Android application, mzCache has demonstrated a 2.1-5.5x reduction in Time-to-First-Token compared to storage-backed partial offload methods. AI
