"""Example script demonstrating running multiple jobs in parallel.
Note the Metafold API applies rate limiting to job dispatches so running jobs in
parallel will give limited performance improvements.
Usage:
python examples/surface_lattice_metrics_parallel.py -t <token> -p <project> -n <procs>
For more details on the available job types please refer to the Metafold REST API
documentation.
