Melvin Strobl 85dad39973 Service node: a server kept running on a worker (openpanel V2)
- `service` node type: command, port, worker label, health path, env and
  weights (an artifact digest the worker fetches as {weights}). Its flow
  starts it; it restarts with backoff, reads degraded while starting or
  without a worker and down after three starts that never got healthy, and
  publishes http://<worker>:<port> once /health answers 200, "" when it ends.
- Worker protocol 3: a `serve` call, every call in its own process group,
  killed when the engine ends the call, the socket drops or the agent gets
  SIGTERM. `--service-host` overrides the address the engine sees.
- Services and compiles take no `--parallel` slot, and a flow's detail is
  built off the event loop, so a save no longer stalls the engine.

Fluksio

Fluksio is a node-based automation software that brings trust and reliability to your flow. It just works and looks good. Get started by running

pip install fluksio
fluksio serve

and you're ready to go.

For data science

You can turn your existing data science project into a flow by decorating your functions with @node ...

# myresearch/train.py
import fluksio
from fluksio import Port, node

@node(
    requires=["dataset", Port("lr", "float")],
    provides=[Port("loss", "float", stream=True), Port("weights", "artifact")],
    worker="gpu", worker_policy="prefer",
)
def fit(dataset, lr, epochs=25):
    for epoch in range(epochs):
        loss = step(...)
        yield {"loss": loss}          # published as it happens, kept as a series
    return {"weights": fluksio.save_artifact("weights.pt")}

... and passing them to a Flow:

# myresearch/pipeline.py
from fluksio import Flow, Port
from myresearch.data import prepare
from myresearch.evaluate import evaluate
from myresearch.train import fit

train = Flow("train", nodes=[prepare, fit, evaluate],
             inputs=[Port("lr", "float", initial=0.01)], outputs=["score"])

Fluksio will automatically infer the order of nodes based on the inputs and outputs you defined. When everything is set, you can launch your first run as follows:

fluksio run train --lr 0.05 --wait

Some other features

  • Flows: typed messages between nodes, wired by name, edited on a canvas or declared in code. Every change is a commit in a git repository you own.
  • Runs: an experiment and a CI-style job are the same entity. Parameters, seed, result, per-node timings, artifacts and the commit it ran at.
  • Dashboards: charts and controls bound to the same messages the flows carry, with no separate metrics pipeline.
  • Remote workers: pip install fluksio-worker on the GPU box; it dials out over one websocket, so nothing there has to be reachable.

Fluksio can also be used for facility automation. Visit us on fluksio.com or go straight to our documentation.
