X-Stream's source code is now available on GitHub under the Apache 2.0 license!
What is X-Stream?
X-Stream is a system for performing analytics on large-scale graphs using secondary storage on a single machine. The system emphasizes sequential data access across all storage mediums — main memory, SSDs, and magnetic disks.
Storage-Centric Philosophy
X-Stream is based on a storage-centric and streaming philosophy that rearranges graph algorithms to stream data directly from storage rather than loading everything into memory first.

Note: While I serve as code maintainer, I was not among the original paper authors. I supervised intern Junyao Zhao in adding HDFS support to the project.
