Overview
SNAP (Small-world Network Analysis and Partitioning) is an extensible parallel framework for exploratory analysis and partitioning of large-scale networks.
SNAP is implemented in C, uses OpenMP primitives for parallelization, and targets sequential, multicore, and symmetric multiprocessor platforms. Our intent with SNAP is to provide a simple and intuitive interface for network analysis and application design, hiding the parallel programming complexity from the user. In addition to path-based, centrality, and community identification queries on large-scale graphs, we support commonly-used preprocessing kernels and quantitative measures that help understand the global network topology.
News
- [August 4, 2010] SNAP 0.4 has been released, plugging memory leaks, fixing modularity calculations for undirected graphs, adding conductance and clustering coefficient metrics, and adding seeded community detection routines.
- [May 25, 2009] Our IPDPS 2009 paper discusses new data structures and parallel algorithms for dynamic network analysis.
- [April 3, 2009] SNAP 0.3 has been released. Several bugs have been fixed, and the interface has been cleaned up. Updates include data structures and traversal algorithms for dynamic network analysis.
- [May 5, 2008] SNAP 0.2 is now available. This version includes a new parallel community identification implementation based on Newman's recursive spectral partitioning algorithm.
- [February 12, 2008] SNAP 0.1 is available for download. This is the first SourceForge release.
- [February 12, 2008] Our IPDPS 2008 paper presents an overview of SNAP and new parallel community identification approaches. Slides on SNAP and a draft user guide have also been posted online.
