Phylanx Report: December 2018

The sixteenth month of work focused on work in the following areas:

• Added 3D tensor support to node_data
• Implementing primitives needed for Keras backend (Issue: #684)
• Modularize Traveler to better support multiple platforms

Development Activities and Results

• Algorithms Highlighted: Logistic Regression, ALS, K-Means
• General
  • Added 3d tensor support to node_data
  • Fixed issues with returns from inner functions
  • Added support for inf, nan, nzero, pzero, e, pi, and euler_gamma to the compiler
  • Created a statistics plugin
  • Work on improving HPX scheduling and tasking
• APEX
  • Working on buildbot issues
  • Fixing APEX policy engine to unload converged policies
• Traveler
  • Design/architecture for modular visualization to more cleanly
    support multiple platforms (e.g., stand-alone, Jupyter)
    • Implementation in progress.
  • Fixes for Docker/Jupyter support
• Tiling
  • Incorporated additional program structures into theoretical formulation
    • Includes conditionals, loops and parallel code execution etc
  • Analyzing requirements of a distributed tiling implementation
• Primitives & Algorithms
  • Added eye, flatten, softmax, reshape, prod, tile, max, min, and flip primitives
    • Supports primitives needed for a Keras backend (Issue: #684)
  • Improvements to squeeze, extract_shape, generic operations primitives, and reshpae primitives
    • Added sinh, cosh, and tanh to generic operations primitive
  • Added support for Sphinx documentation
• Python
  • Enabled the dynamic configuration of HPX from the Python front-end
  • Working on new data structures to represent a Phylanx AST
