oumigo 0.1.0

Vertical-integration toolkit for running and managing GPU fleets with vLLM and Transformer backends.

oumigo

A vertical-integration toolkit for running and managing vLLM replica fleets — a manager/driver node coordinating many independent vLLM worker replicas behind a health-aware router, with a pluggable cloud-provisioning layer.

Status: early development. The CLI, manager console, config resolution, and the LAN provider exist; core worker↔manager registration, the router, and vLLM supervision are not built yet.

Architecture

Two roles:

• Worker (oumigo.service.worker): a long-lived coordinator supervises a vLLM server as a child process, monitors health, executes start/stop/restart from the manager, and owns the node state machine + restart-with-give-up policy. Workers self-register with the manager and heartbeat.
• Manager (oumigo.service.manager): coordinates the fleet, split into sub-layers:
  • control plane (manager.control): tracks worker registrations and state, drives worker lifecycle, reconciles desired vs. actual. Low-frequency, correctness-critical.
  • data plane / router (manager.router): forwards client inference calls to healthy workers — on the hot path of every request.
  • provisioning (oumigo.providers): how workers come into existence — a minimal, lifecycle-shaped Provider protocol used by the control plane. Ships with StaticProvider (LAN: workers are hand-started and self-register, no provisioning); cloud backends (e.g. ConoHa, OpenStack-based) are future implementations of the same protocol.
  • dashboard (manager.dashboard): performance & diagnostics — later.

Shared foundations: oumigo.config (typed settings + precedence resolution) and oumigo.protocol (the wire contract both roles import so it can't drift).

Development

# from oumigo/
python -m venv .venv
source .venv/bin/activate
pip install -e ".[worker,dev]"     # on a GPU worker box
pip install -e ".[manager,dev]"    # on the manager box

To consume this in-development package from a sibling project, editable-install it into that project's environment (e.g. pip install -e ../oumigo).
