Multiprocessing interface

Setup

Use the setup helper script from the project root:

python setup_script.py

This cleans old build artifacts and installs the package in editable mode (pip install -e .).

Show script help:

python setup_script.py --help

Publish workflow (version bump, git commit/push, build, upload):

python setup_script.py -p

Example Workflow

The intended flow is:

1. Start Master(n) with one process per worker.
2. Send one shared dictionary to all workers with send_dict(...).
3. Put everything task strings need inside that dictionary, including functions.
4. Run one task string per worker using run(tasks, "eval") or run(tasks, "exec").
5. Collect outputs with collect().

import operator
from paneltime_mp import Master

master = Master(2)
try:
    payload = {
        "values": [1, 2, 3],
        "factor": 5,
        "mul": operator.mul,
    }
    master.send_dict(payload)
    master.collect()

    tasks = [
        "{'node': 0, 'scaled': [mul(v, factor + 0) for v in values]}",
        "{'node': 1, 'scaled': [mul(v, factor + 1) for v in values]}",
    ]

    master.run(tasks, "eval")
    result = master.collect()
    print(result)
finally:
    master.quit()
