I was selected for GSoC 2021 under the organization Pharo Consortium to work on the project, Matrix State of the Art.
There are several matrix implementations in Pharo. This project aims to compare all those implementations on different parameters like run-time, space efficiency, and features supported.
Then, the project also aims to recommend an implementation that should be used for most use-cases or suggests writing a new implementation from scratch.
The project also involves building a benchmark UI in pharo-spec that lets users specify the benchmark parameters and execute the benchmarks.
- A standalone repository to execute and reproduce the results of the benchmarks.
- Plots of the benchmark results on all the matrix operations supported by the different matrix implementations in Pharo.
- A pharo-spec2 UI package for user-based execution of the Matrix Benchmarking operations, where the users can specify the parameters of interest, run and visualize results in a graphical way.
- Making the old Calipel-S benchmark package compatible on the latest stable Pharo 9.0 version. The new CalipeL-S benchmark package can now be used by all Pharo developers to benchmark their operations.
