Marius

Marius is a system for training graph neural networks and embeddings for large-scale graphs on a single machine.

Marius (OSDI '21 Paper) is designed to mitigate/reduce data movement overheads using:

• Pipelined training and IO
• Partition caching and buffer-aware data orderings

We scale graph neural network training (preprint) through:

• Optimized datastructures for neighbor sampling and GNN aggregation
• Out-of-core GNN training

Build and Install

Requirements

• CUDA >= 10.1
• CuDNN >= 7
• pytorch >= 1.8
• python >= 3.6
• GCC >= 7 (On Linux) or Clang 12.0 (On MacOS)
• cmake >= 3.12
• make >= 3.8

Pip Installation

git clone https://github.com/marius-team/marius.git
pip3 install .

The Python API can be accessed with import marius

The following commands will be installed:

• marius_train: Train models using configuration files and the command line
• marius_eval: Command line model evaluation
• marius_preprocess: Built-in dataset downloading and preprocessing
• marius_predict: Batch inference tool for link prediction or node classification

Command Line Training

First make sure marius is installed with pip3 install .

Preprocess dataset the FB15K_237 dataset with marius_preprocess --dataset fb15k_237 --output_dir datasets/fb15k_237_example/

Train example configuration file (assuming we are in the repo root directory) marius_train examples/configuration/fb15k_237.yaml

After running this configuration, the MRR output by the system should be about .25 after 10 epochs.

Perform batch inference on the test set with marius_predict --config examples/configuration/fb15k_237.yaml --metrics mrr --save_scores --save_ranks

See the full example for details.

Python API

See the documentation for Python API usage and examples.
