Typical Run Times

These are approximate durations for each stage of the simulation pipeline. Actual times vary based on cluster load, network speed, and simulation complexity.

Pipeline Stage	Approximate Duration
Simulator build (fresh)	5–10 minutes
Simulator build (cached / same commit)	seconds
Parca (parameter calculator)	5–8 minutes
Simulation (1 generation, 1 seed)	5–7 minutes
Analysis (8 analysis types)	3–5 minutes
Output download	1–3 minutes (depends on file size and network)
Full pipeline (build + parca + sim + analysis)	~20–30 minutes

Tips:

• Skip parca by omitting --run-parca if a parca dataset already exists for your simulator. This saves ~5–8 minutes.

• Increase --seeds to run multiple independent lineages in parallel. Run time scales sub-linearly since seeds are parallelized on the cluster.

• The simulator build is cached by commit hash. Rebuilding the same commit without --force returns instantly.
