Please note that this page is under construction. We are documenting the 240-node cluster maya that will be available after Summer 2014. Currently, the 84-node cluster tara still operates independently, until it becomes part of maya at the end of Summer 2014. Please see the 2013 Resources Pages under the Resources tab for tara information.
Evaluating Accumulo as a Distributed Semantic Web Triple Store

Semantic Web technologies provide a new approach to to creating, accessing and using distributed, open knowledge using sophisticated knowledge representation concepts coupled with common Web languages and protocols. Since the amount of knowledge available in this form is already large (tens of billions of facts) and expected to grow rapidly, it is important to develop tools that can work at "Web scale".

This project will evaluate parallel approaches to storing, managing and querying Semantic Web data in RDF in a cloud computing environment. Specifically, we will use a set of benchmark datasets to evaluate Accumulo, a distributed key/value store modeled after Google's BigTable, as a store for distributed RDF data when used with an environment provided by Apache Hadoop and Apache Zookeeper.
