Amazon’s Deep Learning Library

DSSTNE (pronounced “Destiny”) is an open source software library for training and deploying deep neural
networks using GPUs. Amazon engineers built DSSTNE to solve deep learning
problems at Amazon’s scale. DSSTNE is built for production deployment of real-world
deep learning applications, emphasizing speed and scale over experimental flexibility.

DSSTNE was built with a number of features for production workloads:

  • Multi-GPU Scale: Training and prediction
    both scale out to use multiple GPUs, spreading out computation
    and storage in a model-parallel fashion for each layer.
  • Large Layers: Model-parallel scaling enables larger networks than
    are possible with a single GPU.
  • Sparse Data: DSSTNE is optimized for fast performance on sparse datasets. Custom GPU kernels perform sparse computation on the GPU, without filling in lots of zeroes.
