GraphChi-cpp/java have reached 0.2 and are now hosted at Github!
From the release notes:
!GraphChi version 0.2 is the first major update to the !GraphChi software for disk-based computation on massive graphs. This upgrade brings two major changes: compressed data storage (shards) and support for dynamically sized edges.
We also thank for your interest on GraphChi so far: since the release in July 9th 2012, there has been over 8,000 unique visitors to the Google Code project page, at least 2,000 downloads of the source package, several blog posts and hundreds of tweets. GraphChi is a research project, and your feedback has helped us tremendously in our work.
Enjoy!
