GraphChi brings web-scale graph computation, such as analysis of social networks, available to anyone with a modern laptop or PC. It saves you from the hassle and costs of working with a distributed cluster or cloud services. We find it much easier to debug applications on a single computer than trying to understand how a distributed algorithm is executed. If you do require the processing power of high-performance clusters, GraphChi can be an excellent tool for developing and debugging your algorithms prior to deploying them to the cluster. GraphChi supports most of the new GraphLab v2.1 API (with some restrictions), making the transition easy.
