Heap hot spots visualization in Java

Abstract

Data memory (heap) management is a particularly important feature of the Java programming environment. The visualization of memory location in form of hot spots can help to see how the data cache is used during the execution of a program. The behavior of such executed program can be thus speculated. Through a series of experiments using Load and Store trace files, some pertinent aspect of data memory accessing, can be visualized, including the frequency of how often the Java virtual machine references class variable addresses. A demonstration will be included showing how object variables are accessed in the heap by allowing one to visualize (X, Y) graph hot spots.
