Parent: [Local Inference Acceleration: Memory Architectures, Metal Kernels, and Latency Optimization](https://llms-explorer.com/tree/local-inference-acceleration-and-kernels/) · 1 facets · 2 facts · page: https://llms-explorer.com/tree/wired-memory-instrumentation-and-static-activation-buffers/ ## Facts and statements - Allocating inference memory as wired pages on macOS prevents the virtual memory subsystem from paging model weights to swap disks, ensuring consistent sub-millisecond tensor read latencies. (high confidence) — [source](https://developer.apple.com/documentation/metal/unified_memory_architecture) - Pre-allocating static activation workspaces at engine startup eliminates dynamic memory allocation overhead and kernel locks during the generation loop.
