MapReduceXMT from Sandia National Laboratories.

Welcome to MapReduceXMT
MapReduceXMT is a library that ports the MapReduce paradigm to the Cray XMT.
MapReduceXMT is copyrighted and released under a Berkeley open source license. However, the code is still very much in development and there has not been a formal release of the software.
SPEED-MT Semantic Processing Executed Efficiently and Dynamically
This trac site is currently being used to house SPEED-MT, which contains a set of algorithms and data structures for processing semantic web data on the Cray XMT.
- Dictionary Encoding
- RDFS/OWL Closure
- RDF Stats
- RDF Dedup
OK, so this one is tied a little more closely to the Cray XMT. 😉
But modules are ones that are likely to be of interest for processing RDF triples/quads.
