The twenty-fifth month of work focused on work in the following areas:
- Cross platform support for Traveler-Integrated
- 4D primitive support
- Improved support for Docker containers
Organizational Activities and Results
- Weekly group-meeting, minutes:
- Phylanx Seminars:
Development Activities and Results
- Traveler
- Refactored Traveler-Integrated to work on MacOS and Ubuntu
- Already worked on Windows
- Updated Atria instances to support linked highlighting and Ctrl-F search for text within the visualization
- Stand-alone & Traveler-Integrated
- Improvements to Traveler-Integrated Gantt view in terms of highlighting primitives of the same type.
- Traveler-Integrated backend changes to support dependency-analysis between tasks in trace files (e.g., Gantt views)
- Tiling
- Theory:
- Derived an on online sub modular function maximization with respect to a greedy algorithm
- Some observations were made on the online min cut on random graph
- Implementation
- Work on the distributed matrix matrix dot operation
- Developing windows build scripts
- Implementing an annotation comparison operator
- Primitives & Algorithms
- 4D support was added to the following:
- squeeze operation (PR #1043)
- conv2d operation (PR #1042)
- logical operation (PR #1039)
- transpose operation (PR #1030)
- Bias_add operation was added (PR #1031)
- Updated resize_images(PR #1034) and pool2d(PR #1033) to accept 4d arrays as input
- Python
- Wrote utility scripts to build, run and manage docker images based on both ‘docker-compose.yml’ and ‘Dockerfile’ files
- This will allow users to:
- build desired environment (development, performance analysis, or release) by passing a few parameters to the script
- Dynamically build and deploy Phylanx environments.
- Studying performance of the blaze library and approaches to improve it.
- Focused on BBLAS (Batched BLAS) library as an alternative back-end to Blaze
- This will help us:
- Achieving better performance for applications dealing with many operations on small matrices (convolution, FEM, …)
- Gain full control over blocking for any granularity
