2015 Grant Accomplishment Report
The following three projects have been completed, and their deliverables have been accepted by the grant committee.
- reality gem
- FFTW and GSL extensions for NMatrix
- Optimization of CRuby built-in library Rational
reality gem
Victor Shepelev
Reality provides easy access to “common” world knowledge (like geography, currencies, movies, historical events and people, weather and so on). It utilizes multiple open data sources, like Wikipedia, OpenStreetMap, TheMovieDatabase, and presents consistent, integrated approach to various aspects of data.

FFTW and GSL extensions for NMatrix
Sameer Deshmukh
NMatrix is a dense and spare matrix linear algebra library for ruby by SciRuby. It supports an extensions interface that allows interfacing of various high speed C libraries with nmatrix data types by creating new gems that bind these libraries (like BLAS or LAPACKE). Extensions like nmatrix-lapacke are already in existence. This project will aim to create two new extensions for nmatrix. One for interfacing nmatrix with FFTW (Fastest Fourier Transform in the West) and another for interfacing with GSL (GNU Scientific Library). Both these extensions will be released as nmatrix-fftw and nmatrix-gsl gems respectively by the end of the grant term.

Optimization of CRuby built-in library Rational
Tadashi Saito
By optimizing the Rational implementation of CRuby, I aim to improve its overall speed. I’ll write mergeable patch into the upstream.
