The "PoweredBy" page has been changed by AlexanderSchaetzle. http://wiki.apache.org/hadoop/PoweredBy?action=diff&rev1=253&rev2=254 -------------------------------------------------- . We currently run one medium-sized Hadoop cluster (1.6PB) to store and serve up physics data for the computing portion of the Compact Muon Solenoid (CMS) experiment. This requires a filesystem which can download data at multiple Gbps and process data at an even higher rate locally. Additionally, several of our students are involved in research projects on Hadoop. * [[http://dbis.informatik.uni-freiburg.de/index.php?project=DiPoS|University of Freiburg - Databases and Information Systems]] - * 10 nodes cluster (Dell PowerEdge R200 with Xeon Dual Core 3.16GHz, 4GB RAM, 3TB/node storage). + . 10 nodes cluster (Dell PowerEdge R200 with Xeon Dual Core 3.16GHz, 4GB RAM, 3TB/node storage). . Our goal is to develop techniques for the Semantic Web that take advantage of MapReduce (Hadoop) and its scaling-behavior to keep up with the growing proliferation of semantic data. * [[http://dbis.informatik.uni-freiburg.de/?project=DiPoS/RDFPath.html|RDFPath]] is an expressive RDF path language for querying large RDF graphs with MapReduce. * [[http://dbis.informatik.uni-freiburg.de/?project=DiPoS/PigSPARQL.html|PigSPARQL]] is a translation from SPARQL to Pig Latin allowing to execute SPARQL queries on large RDF graphs with MapReduce.
