# Lane 2 / #30 KV-cache mini-comparison.
# Compares three KV-cache configurations against the FP16 baseline using the
# canonical SGT-009 multi-domain scenario through the AaT direct path:
# 1. baseline (no KV optimization)
# 2. --enable-prefix-caching (chosen for Cell C)
# 3. --enable-prefix-caching --kv-cache-dtype fp8 (originally planned;
# failed in prior
# FP16/H100 smoke —
# see status doc)
# One run per variant; all variants use the same model, scenario, and prompt
# template so latency deltas attribute to KV-cache. The fp8 variant is
# expected to fail at vLLM startup; the summary step degrades gracefully.
#
# Wall-clock ~10-20 min once allocated (3 vLLM startups + 1 trial each).
#
# Usage:
# sbatch --mail-type=BEGIN,END,FAIL --mail-user=$USER@example.edu \
# scripts/test_kv_cache_smoke.sh
#
# Outputs:
# benchmarks/cell_A_direct/raw/<JOB>_lane2_kv_<variant>/ (per-variant trial JSON)
# docs/lane2_int8_kv_status.md (manual update with the result table after the run)
#
# After completion, summarize with:
# bash scripts/test_kv_cache_smoke.sh --summarize <JOB>
set -euo pipefail
# Self-summarize mode: bash scripts/test_kv_cache_smoke.sh --summarize <JOB>
