# Run-queue shootout driver (ROADMAP_v0.5 phase 4; RFC 005 slot dimension
# added for the v0.9 slot shootout).
#
# Rebuilds the runtime bench once per rq-* feature and runs the raw-structure
# microbench once (it covers all structures in a single binary). The RFC 005
# wake slot is a runtime Config knob, NOT a feature — each rq_runtime binary
# sweeps slot off/on internally (SMARM_BENCH_SLOT, default "0 1"). Results
# land in bench_results/ as full logs; the RQCSV lines are aggregated into
# bench_results/summary.csv and the RQSLOT counter lines (slot hits /
# displacements, slot-on configs only) into bench_results/slot_counters.csv.
#
# Tune the sweep for the box, e.g. on the 20-core machine:
#   SMARM_BENCH_THREADS="1 2 4 8 16 20" ./scripts/bench_rq.sh
# Slot-only re-run against the frozen rq-mutex substrate:
#   SMARM_BENCH_SLOT="0 1" cargo bench --bench rq_runtime
