UMBC High Performance Computing Facility
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.
