Development Activities and Results
- Algorithms Highlighted: Logistic Regression, ALS, K-Means
- APEX
- Improving Phylanx Build system
- Traveler
- Traveler Tree visualization now supports direct comparison of two
runs- Directly displays performance differences
- Initial release of Roundtrip library
- Integrates Javascript visualizations into Jupyter, in support of the Traveler Tree and future visualizations (https://github.com/hdc-arizona/roundtrip)
- Traveler Gantt chart build fixes for Linux systems, now available at
https://github.com/hdc-arizona/traveler-gantt
- Traveler Tree visualization now supports direct comparison of two
- Tiling
- Theory:
- Worked on completing formulation for the previous tiling model
- Assumptions:
- Number of matrices (n) are given as an input
- User program consists of a number of (m) matrix operations taken from a fixed collection F
- Assumptions:
- Results:
- A 0-1 integer programing model for generic tiling problem (a version of a tiling problem with fewest simplifying assumptions)
- Provided a reduction from the balanced subgraph problem to a special case of the generic tiling problems showing the problem is , at least theoretically, hard to approximate.
- The model also includes memory constraints.
- Due to several changes from our last iteration (see the last technical report from Nov 18) we are still in the process of incorporating these new additions into a tech report with a possibility of a future publication.
- Looking at a more useful tiling model, wherein the user program consists of a fixed set matrices but the program itself may be arbitrary.
- Worked on completing formulation for the previous tiling model
- Implementation:
- Added VSlipt and HSplit primitives
- Reviewed distributed matrix libraries.
- Researched methods of implementing distributed matrix operations using Blaze.
- Theory:
- Primitives & Algorithms
- Primitives Added:
- 3D Support is now available in Phylanx
- Support for 3D tensors added in new repo: Blaze Tensor (https://github.com/STEllAR-GROUP/blaze_tensor)
- The following primitives can now take advantage of 3D tensors:
- Python
- Work on distributed computation in Phylanx
- Created new data structures to represent PhyLS in the Python front-end
- Implemented a symbol table which tacks all objects and their namespaces in Phylanx
- Work on distributed computation in Phylanx
