Carrot2: framework for building document clustering engines

Carrot2 is a framework for building document clustering engines. Apart from two specialized document clustering algorithms, Carrot2 offers ready-to-use components for fetching search results from various sources such as public search engines. Lingo3G seamlessly integrates with Carrot2.

Randomized Testing

Randomized tests are a wildly successful way to show the cracks in your software. Also contains an Ant task (and Maven goal) to run JUnit4 tests in parallel. Recommendation: project used by Apache Lucene/ Solr!

HPPC: Hight Performance Primitive Collections for Java

Lists, Sets, Maps and other collections of primitives for Java tuned for highest performance and memory efficiency.

JUnitBenchmarks: Performance benchmarking for JUnit4

A set of extensions for turning your JUnit4 tests into performance micro-benchmarks with GC monitoring, time variance measurement and simple graphical visualizations.
