NumaGiC is a version of the HotSpot garbage collector (GC) adapted to many-core computers with very large main memories. In order to maximise GC throughput, it manages the trade-off between memory locality (local scans) and parallelism (work stealing) in a self-balancing manner. Furthemore, the collector features several memory placement heuristics that improve locality. NumaGiC is described in a paper accepted for publication at ASPLOS 2015 [29] .
