Bench changes:
- new _end_to_end_ns(op_log) and _engine_occupancy_ns(op_log) helpers
in milestone_gqa_decode_long_ctx_4cases.py (mirror paper_gqa_latency.py)
- _run_panel return dict now carries latency_ns + engine_occupancy_ns
alongside op_log_summary, so sweep.json is the single source of truth
for the comparative figures
Plot script:
- new scripts/paper/paper_plot_gqa_decode_long_ctx_4cases.py reads
sweep.json and emits 3 PNGs to docs/report/1H-codesign-paper/figures/:
gqa_decode_long_ctx_4cases_latency.png (end-to-end latency / case)
gqa_decode_long_ctx_4cases_traffic.png (ipcq/dma op counts / case)
gqa_decode_long_ctx_4cases_memory.png (KV bytes per cube / case)
Test changes:
- 2 new tests verifying the helpers + _run_panel dict shape
- lower smoke S_kv from 8192 -> 2048 (4x faster Case 2; assertions
are S_kv-independent; one fold-loop iteration preserved)
18/18 tests pass in ~4 min.
