The Eight month of work was focused on work in the following areas:
- Performance analysis and Improvement
- Trace Visualization
- Jupyter Visualization
- Python Bindings
Organizational activities and results
- Year 2 Project Kickoff Meeting: http://phylanx.stellar-group.org/index.php/events/phylanx-year-2-kickoff-meeting/
- Weekly group-meeting, minutes:
Development activities and results
- Algorithms Highlighted: Logistic Regression, ALS, K-Means
- Refactoring: Enabled primitives to be loaded from separate shared libraries (#345)
- Reduces link time
- Moved primitives into plugins directory
- Split primitives into subdirectories
- Improvements to the slicing primitive
- Performance Improvements
- Working range primities (#355)
- Performance measurements of Phylanx and “competing” solutions have been completed
- APEX policy to support parcel coalescing has been resurrected, future improvements are planned
- Jupyter Integration:
- Initial implementation of “magics” in Jupyter notebook for visualization support
- Performed a formative evaluation study with Phylanx developers to assess/improve next iteration of design
- Trace Visualization
- All tasks are now traced with GUIDs and are added to the OTF2 file
- Visualization now reads and displays new HPX parent thread dependencies collected by APEX
- Verified code works for a Phylanx LRA trace
- Phylanx Front End
- Exposed AST as a member function of the @Phylanx decorator
- Incorporating new slicing primitive into front-end
- Convert python loops into Phylanx maps
- Uses new map and range primitives
- Redirected all std::cout outputs to Python’s stdout
- Improved handling of return statements in Phylanx Kernels
