Pregelix: Big(ger) Graph Anayltics on a Dataflow Engine - Bu et al. 2015 FlashGraph shows us that it's possible to efficiently process graphs that aren't solely in-memory, and GraphX showed us that we can map graph abstractions on top of a dataflow engine. Put the two ideas together, and you get something that looks like … Continue reading Pregelix: Big(ger) Graph Analytics on a Dataflow Engine

FlashGraph: Processing Billion Node Graphs on an Array of Commodity SSDs
FlashGraph: Processing Billion Node Graphs on an Array of Commodity SSDs - Zheng et al. The Web Data Commons project is the largest web corpus available to the public. Their hyperlink (page) graph dataset contains 3.4B vertices and 129B edges contained in over 1TB of data, and a graph diameter of 650. To the best … Continue reading FlashGraph: Processing Billion Node Graphs on an Array of Commodity SSDs
GraphX: Graph Processing in a Distributed Dataflow Framework
GraphX: Graph Processing in a Distributed Dataflow Framework - Gonzalez et al. 2014 This is the second of two weeks dedicated to graph processing. So far in this mini-series we've looked at what we know about networks of complex systems and graphs that model the real-world; Google's Pregel which led to a whole set of … Continue reading GraphX: Graph Processing in a Distributed Dataflow Framework
PowerGraph: Distributed Graph-Parallel Computation on Natural Graphs
PowerGraph: Distributed Graph-Parallel Computation on Natural Graphs - Gonzalez et al. 2012 A lot of the time, we want to perform computations on graphs that model the real world. As we saw in Exploring Complex Networks, such graphs often follow a power-law degree distribution (i.e., a few nodes are very highly connected, and many nodes … Continue reading PowerGraph: Distributed Graph-Parallel Computation on Natural Graphs
Distributed GraphLab: A framework for machine learning and data mining in the cloud
Distributed GraphLab: A framework for machine learning and data mining in the cloud - Low et al. 2012 Two years on from the initial GraphLab paper we looked at yesterday comes this extension to support distributed graph processing for larger graphs, including data mining use cases. In this paper, we extend the GraphLab framework to … Continue reading Distributed GraphLab: A framework for machine learning and data mining in the cloud
GraphLab: A new framework for parallel machine learning
GraphLab: A new framework for parallel machine learning - Low et al. 2010 In this paper we propose GraphLab, a new parallel framework for ML which exploits the sparse structure and common computational patterns of ML algorithms. GraphLab enables ML experts to easily design and implement efficient scalable parallel algorithms by composing problem specific computation, … Continue reading GraphLab: A new framework for parallel machine learning
Pregel: A System for Large-Scale Graph Processing
Pregel: A System for Large-Scale Graph Processing - Malewicz et al. (Google) 2010 "Many practical computing problems concern large graphs." Yesterday we looked at some of the models for understanding networks and graphs. Today's paper focuses on processing of graphs, especially the efficient processing of large graphs where large can mean billions of vertices and … Continue reading Pregel: A System for Large-Scale Graph Processing
FAWN: A Fast Array of Wimpy Nodes
FAWN: A Fast Array of Wimpy Nodes - Andersen et al. 2009 A few days ago we looked at FaRM (Fast Remote Memory), which used RDMA to match network speed with the speed of CPUs and got some very impressive results in terms of queries & transactions per second. But maybe there's another way of … Continue reading FAWN: A Fast Array of Wimpy Nodes
TAO: Facebook’s Distributed Data Store for the Social Graph
TAO: Facebook's Distributed Data Store for the Social Graph Bronson et al. (Facebook) 2013 A single Facebook page may aggregate and filter hundreds of items from the social graph. We present each user with content tailored to them, and we filter every item with privacy checks that take into account the current viewer. This extreme … Continue reading TAO: Facebook’s Distributed Data Store for the Social Graph
Practical Byzantine Fault Tolerance
Practical Byzantine Fault Tolerance - Castro & Liskov 1999 Oh Byzantine, you conflict me. On the one hand, we know that the old model of a security perimeter around an undefended centre is hopelessly broken (witness Google moves its Corporate Applications to the Internet)- so Byzantine models, which allow for any deviation from expected behaviour … Continue reading Practical Byzantine Fault Tolerance
