cycle_bench

Per-program Risc0 cycle counts, prover wall time, PPE composition cost, and verifier wall time for the built-in LEZ programs. Feeds the fee model (G_executor, G_prove, G_verify, S_agg).

Run

The binary handles executor cycles, prover wall time, and PPE composition cost:

# Executor cycles only (fast, ~seconds)
cargo run --release -p cycle_bench

# + real proving per program (slow, ~minutes)
cargo run --release -p cycle_bench --features prove -- --prove

# + PPE composition cases (very slow, ~hour)
cargo run --release -p cycle_bench --features ppe -- --prove --ppe

The verifier microbenchmark (G_verify) lives in a criterion bench under benches/verify.rs:

# Generates one PPE receipt for auth_transfer Transfer (~minutes of setup),
# then times Receipt::verify under criterion's statistical sampler.
cargo bench -p cycle_bench --features ppe --bench verify

RISC0_DEV_MODE=1 skips proving entirely and is only useful for the executor path. The bin writes to target/cycle_bench.json; criterion writes per-bench estimates under target/criterion/.

What you'll see

• Per-program executor cycles and segments, plus exec wall time as best / mean ± stdev (n=N).
• With --prove: prover total cycles, paging cycles, segments, and wall time.
• With --ppe: end-to-end execute_and_prove wall time and S_agg (the borsh-serialized InnerReceipt length) for one auth-transfer-in-PPE case and a chain-caller depth sweep.
• From the verify criterion bench: ppe/verify_auth_transfer slope-regression point estimate with 95% CI bounds.
