Changelog

0.22.0 - 22/7/2024

General System Refactoring

• Renamed NODE to WORKER and restructured WORKER packages (#477)
  • Worker is packaged by feature, including exareme2/flower packages.
  • Fixed version incompatibility issues between pre-commit config and poetry.
  • Resolved a bug in Kubernetes templates.
• System tables are loaded from SQLite (#488)
• Refactored Task Handlers (#476)
  • Restructured the tests to align with the project structure. (#479)
• Refactored Algorithm Specifications (#480)
  • Specifications are now loaded via JSON files.
  • Added type specifications to algorithms in preparation for integrating Flower.

Algorithms

• Dev/mip 897/add log transformation (#487)
  • Added PCA with transformations

Flower Integration

• Integrated Flower Federated Learning Framework (#478)

  • New Controller for Flower Execution:
    • Introduced a controller with modules for managing Flower workflow and algorithm execution.
  • Added Flower-Compatible Algorithms:
    • Logistic Regression with MIP Data: Utilizes MIP data with parameter customization.
    • Logistic Regression with MNIST Data: Tailored for MNIST data operations.
  • Robust Process Management Module:
    • Enhanced process control with functions for sending signals, checking status, managing zombie processes, and process termination with retry capabilities.
    • The controller uses this module to initiate, monitor, and safely terminate Flower execution processes, ensuring better oversight of Flower's client and server components.
    • Lowered local workers in production tests due to increased resource usage by Flower and controller.
    • Implemented process garbage collection at the start of each Flower algorithm.

• Error Handling: (#482)

• Dev/mip 902/flower logging (#486)

  • Added a Flower logger similar to the worker.

• Retry mechanism for Flower client-server connections. (#484)

• Implemented DataFrame filter for Flower inputdata processing. (#485)

• Test Data Loaded on GlobalWorker (#489)

  • Integrated Mipdb into GlobalWorker for dataset monitoring by Worker Landscape Aggregator (WLA).
  • Added test datasets, excluded from Exareme2 flow.

• Inputdata: Split datasets to training datasets and validation datasets. (#490)

• Updated deployment logic:

  • Kubernetes: Ensure GlobalWorker deployment even in single-worker setups.
  • Flower: Configure server to run on GlobalWorker.

0.21.2

Changlog:

• Relaxed the validation of the filter values.
