Ulysses is an intelligent TPF client that takes advantage of replicated datasets to distribute the load of SPARQL query processing and provides fault-tolerance. By reducing the load on a TPF server, Ulysses improves the Linked Data availability and distributes the financial costs of queries execution among data providers. This demonstration presents the Ulysses web client and shows how users can run SPARQL queries in their browsers against TPF servers hosting replicated data. It also provides various visualizations that show in real-time how Ulysses performs the actual load distribution and adapts to network conditions during SPARQL query processing.
