# Experiment 1c: hash-rate steps for the difficulty controller (spec 02 section 2.3; the dual-lane rule is on the

# selector: all | half (odd indices) | odd | even | region:<name> | <from>-<to> (indices)

# threads: miner threads on the selected nodes (0 stops the miner); unselected nodes keep their setting

# Default schedule (about 75 min): steady, 4x step up on half the nodes, back down, one region off, back:
