PoC для validation концепта перед инвестированием в Phase 1. Структура: - tools/spike/common.h — типы SharedHeader / SlotDescriptor / NV12 meta - tools/spike/pingpong_producer.cu — аллоцирует CUDA pool, экспортирует IPC handles в /dev/shm/cuframes-spike-<key>, имитирует publish frames с monotonic pattern - tools/spike/pingpong_consumer.cu — открывает handles, читает frames, verify содержимого (no torn frames), измеряет latency, печатает summary - tools/spike/CMakeLists.txt — sm_75/86/89/90/120 для RTX 5090 - tools/spike/bench.sh — basic / multi-consumer / stress scenarios - tools/spike/README.md — what / how / acceptance Намеренные упрощения PoC (не идём в Phase 1 пока без validation): - 2-slot ring (Phase 1 будет N) - POSIX shared memory + atomic seq (без Unix socket handshake) - cudaStreamSynchronize sync (Phase 0 spike проверит будет ли достаточно; альтернатива cudaIpcEventHandle_t — отложена) - NV12 hardcoded (других форматов в Phase 1) - Drop-oldest backpressure (без ACK protocol) Acceptance Phase 0: - p99 latency на RTX 5090 для FullHD < 5 ms - throughput ≥ 1 GB/s - multi-consumer (3) с сопоставимой latency - cross-container работает - 1-hour stress без VRAM/RAM leak Если acceptance fail → дизайн пересмотр (sync через CUDA IPC events).
