"""
|
||||
Dispatch phase 3 experiment runs to the distributed job server.
|
||||
|
||||
Reads experiment_grid.json, checks which runs already have complete 10x5 results,
|
||||
and submits the rest via submit-cv. Skips runs marked needs_implementation.
|
||||
|
||||
Usage:
|
||||
python -m v3.scripts.main.phase3.dispatch_phase3 \
|
||||
--server http://hades:8765 --token hypertower
|
||||
|
||||
# Dry run (print what would be submitted, don't actually submit):
|
||||
python -m v3.scripts.main.phase3.dispatch_phase3 \
|
||||
--server http://hades:8765 --token hypertower --dry-run
|
||||
|
||||
# Override number of reps (default 10):
|
||||
python -m v3.scripts.main.phase3.dispatch_phase3 \
|
||||
--server http://hades:8765 --token hypertower --reps 4
