A Performance Evaluation of Open Source Graph Databases

Rob McColl presented work comparing a performance evaluation of a variety of open source graph database technologies today at the 1st Workshop on Parallel Programming for Analytics Applications (PPAA 2014) held in conjunction with the 19th ACM SIGPLAN Symposium on Principles and Practice of Parallel Programming (PPoPP 2014).  Slides and the [...]

Next Gen STINGER Python Interface for Prototyping

The Next Gen development version of STINGER (https://github.com/robmccoll/stinger) now has Python ctypes interfaces to the STINGER core library and the STINGER net library.  These enable the use of STINGER in standalone applications and in the streaming processing pipeline as a data stream, algorithm, or monitor.  These libraries can be [...]

The Next Generation of STINGER

For the past several months, members of our group have been developing a suite of tools built on top of the core STINGER graph data structure to simplify the process of getting streaming data into STINGER, maintaining the online analytics, and getting useful data out from the algorithms.  Today we are publicly announcing our efforts and maki [...]

Updates to STINGER r633

STINGER r633 has been updated to repair the Java and Python library targets on Mac.  The targets should both function correctly with the GCC and Clang targets.

A Statistical Framework for Analyzing Streaming Graphs

James Fairbanks is presenting work on frameworks for analyzing the evolution of dynamic graphs using statistical techniques today at the 2013 IEEE/ACM International Conference on Advances in Social Networks Analysis and Mining (ASONAM 2013). Abstract—In this paper we propose a new methodology for gaining insight into the temporal aspects [...]

STINGER r633 Stable Release

Changes: Many changes and updates to Jason Riedy's community-el code. Fix in rmatter deduplication Adds detailed Getting Started README.md (see here) Fixed static library target Removing the test library Fixes Mac build issues resulting from librt dependency You can download the code from this direct link or the do [...]

New Publication: Multithreaded Community Monitoring for Massive Streaming Graph Data

Jason Riedy is presenting work using the STINGER framework to track communities at rates of up to 100 million updates per second at the 7th Workshop on Multithreaded Architectures and Applications (MTAAP) in Boston.  The approach re-agglomerates around only the portions of the graph that change to minimize unneeded computation. Abstract&md [...]
