R is the most popular language in the data science community with 2+ million users and 4000+ R packages. R’s adoption evolved with it’s easy to use statistical language, graphics, packages, tools and an active R community. In this session we will introduce new open source technology Distributed R that solves the scalability and performance limitations of the standard R language. Since R is single-threaded and does not scale to large datasets, we have built Distributed R, a distributed system that extends R and addresses many of its limitations. Distributed R efficiently shares sparse structured data, can leverage multi-cores, and dynamically partitions data to mitigate load imbalance. Our results show the promise of this approach: many important machine learning and graph algorithms can be expressed in a single framework and are substantially faster.

By combining Distributed R with the columnar analytic database technology data scientists now can build complex machine learning models on terabytes of data without sampling.

This session is sponsored by HP
