# CatOpt-Flow: Category-Theoretic Compositional Optimizer CatOpt-Flow is a production-grade, open-source platform for defining and solving per-job optimization problems in multi-tenant ML training pipelines across heterogeneous accelerators. Key abstractions (category-theory inspired) - Objects: local training tasks representing per-job optimization problems. - Morphisms: data-exchange channels with versioned schemas (signals like resource usage, gradient statistics, throughput metrics). - Functors: adapters mapping device-specific problems to a vendor-agnostic representation. - Limits/Colimits: global constraints and governance that aggregate local problems into a coherent global plan. - Delta-sync: a lightweight delta-based synchronization protocol enabling asynchronous updates and partial failures. - Schema registry and contract marketplace: plug-and-play adapters for major ML frameworks and hardware backends. - Code generation: orchestration stubs (Rust/C++) and Python bindings for rapid deployment. What you get - A pragmatic, test-driven architecture suitable for large-scale, multi-tenant ML workloads. - A ready-to-extend core, with simple yet expressive primitives and a working ADMM-like solver MVP. - A packaging-ready Python distribution with tests that exercise the core primitives. Getting started - This is a Python project. You can run tests and build the package with the provided script: - bash test.sh - The test suite validates core functionality: object/morphism relations, local/global planning, and an ADMM-like convergence flow. - The packaging step exercises Python packaging metadata and wheel/sdist generation. What’s inside - catopt_flow_category_theoretic_compositi/core.py: core primitives (Object, Morphism, LocalProblem, GlobalProblem, Functor, Planner, DeltaSyncRegistry, ADMMNode, run_admm). - tests/test_core.py: unit tests for core primitives. - A minimal, production-ready packaging layout with pyproject.toml and a README hook. Development and contribution - See AGENTS.md for architectural guidelines and contribution rules. - All changes should be reflected in tests and documented in this README. Roadmap (high level) - Phase 0: protocol skeleton with 2 starter adapters per platform and delta-sync. - Phase 1: governance ledger with DID-based identities. - Phase 2: cross-domain demo with a simulated satellite domain. - Phase 3: hardware-in-the-loop validation. - A small DSL sketch (LocalProblem/SharedVariables/PlanDelta) and a Graph-of-Contracts registry. This project aims for clean, production-grade code with strong test coverage and clear extension points.
