F894 — GPU Working Cortex Cache
F894 covers “GPU Working Cortex Cache”. The canonical record classifies it as validated, based on 2 source artifacts and 1 original source figure. The highlighted measurements are Pass = Yes, Cpu Passed = 6, and Cpu Pass Rate = 1.
Purpose and research question
F894 evaluated a GPU working-cortex cache candidate under cold and warm-cache conditions, asking whether repeated recall could offset GPU setup cost without changing the language path or promoting a new runtime default.
Method
F894 simulated 20,000 working-cortex rows and ran six probes in each CPU, cold-GPU, and warm-cache condition. It counted cold GPU executions and hot cache hits, measured average latency for all three paths, and added a two-call reason-memory smoke at a 32-row threshold; the default 128-row threshold and runtime promotion state remained unchanged.
Documentation basis
2 source artifacts and 1 phase-specific figure are recorded for this phase.

Public evidence and source figures
These are original source figures from the existing public evidence set, not editorial HTML visualizations.
Result and interpretation
CPU average latency was 26.597 ms, GPU cold latency 151.391 ms, and GPU hot latency 6.09 ms. All 6 cold probes used the GPU and all 6 hot probes hit the cache. The candidate passed as a warm-cache optimization, but the report explicitly recorded no promotion.
