Update Apache REEF and Checkstyle.
Latest commit 55ee12a May 31, 2016


Dolphin is a machine learning platform built on top of Apache REEF. Dolphin consists of a BSP-style machine learning framework (dolphin-bsp), a deep learning framework (dolphin-dnn), and a parameter server module (dolphin-ps).


  • dolphin-bsp: BSP-style framework for multi-staged processing.
  • dolphin-dnn: Deep learning framework for training deep neural network models on large datasets.
  • dolphin-ps: Parameter server module for asynchronous machine learning algorithms.

How to build and run Dolphin

  1. Build REEF: check Currently, Dolphin depends on REEF 0.14.0-SNAPSHOT, which means you must build the current snapshot of REEF before building Dolphin. We will move to the release version 0.14.0 once it's out.

  2. Build Dolphin:

    git clone
    cd dolphin
    mvn clean install
  3. Run Dolphin: check the READMEs in the submodules for more details.
