I want to analyze the memory usage used by this program
This article (http://virtualthreads.blogspot.com/2006/02/understanding-memory-usage-on-linux.html ) recommends "pmap" to get more accurate picture [please see code snippet for result]. It mentions that I need to look at the "writeable/private" at the bottom of the result of running pmap command. I'm really confused why it is using 225,024K. Why is this? Originally, I thought capping the heap size would help, but I don't understand why that much memory is being used.
