If we were able to take a microscope and observe how our programs work on the lowest level, we would be surprised and shocked. Close to the wire, programs behave very differently from what we expect. In this session we will go through code examples that show the counter-intuitive behavior of Java on the lowest level. Topics covered will be the cache hierarchy, false sharing, pipelining, branch prediction, and out-of-order execution.
