FlashX performs data analytics in the form of graphs and matrices. It runs on a variety of hardware and can utilize solid-state drives (SSDs) to scale to large datasets in a single machine. The goal of FlashX is to process massive datasets with extreme efficiency in a single machine. Right now, FlashX provides the R programming interface.

FlashX has three main components:

  • FlashGraph is a general-purpose programming framework with a vertex-centric programming interface for large-scale graph analysis. FlashGraph is able to scale to billion-node graphs in a single machine and significantly outperforms state-of-art distributed graph analysis frameworks at this scale.
  • FlashMatrix is a matrix computation engine that provides generalized matrix operations (GenOps). FlashMatrix uses a small set of GenOps to support a large variety of matrix operations and express varieties of data mining and machine learning algorithms. It keeps matrices on SSDs to scale to very large datasets.
  • FlashR reimplements matrix operations in the R framework with GenOps of FlashMatrix. With the help of FlashR, R users can execute existing R code to process datasets at a scale of terabytes with the speed of optimized parallel C code.


Quick Start

We provide instructions to install FlashX and use some simple examples to show how to use FlashR for computation.


We show the lightning speed of FlashX, compared with its main competitors.

User Guide

FlashX provides both C++ and R programming interfaces. We provide multiple user guide to explain these interfaces of FlashGraph and FlashMatrix.


This lists specific applications and shows how to solve them with FlashX.


We hope more people will help and develop FlashX together to make this a successful project. Here we list a number of tasks in the TODO list.


FlashX exposes both C++ interface and R interface.
