## Description

Angel is a distributed machine learning framework and graph computation engine designed to train predictive models and execute algorithms across a cluster of servers. It functions as a distributed parameter server that synchronizes model weights and gradients across multiple machines to handle massive datasets.

The system provides a production environment for model inference deployment to provide real-time predictions for end users. It integrates with Spark to run machine learning workflows and data processing pipelines through a compatible interface.

The framework covers distributed graph computation for tasks such as PageRank and community detection, as well as automatic hyperparameter optimization to improve model accuracy. It includes capabilities for coordinating distributed training, partitioning model data, and orchestrating cluster resources via container-based scheduling.
