#1 Open-source machine learning platform for enterprises

Download Documentation

Combine the power of highly advanced algorithms, the freedom of open source, and truly scalable in-memory processing for big data on one or many nodes.

Fast & Accurate

The responsiveness of in-memory processing and the ability to run fast serialization between nodes and clusters are combined—so you can support the size requirements of your large data sets.


Fine-Grain distributed processing on big data at speeds up to 100x faster is done with fine-grain parallelism, which enables optimal efficiency, without introducing degradation in computational accuracy.
