Application should _not_ share memory across processes. That's a security vulnerability. One app could corrupt memory, and cause unpredictable results in another process. You can check for processes which share memory by looking for the GNU_SHARED section attribute in a [on-disk] program. There should be no shared sections. Tobias Klein's checksec may show programs which have GNU_SHARED . If checksec does not check for it, then `readelf -l <program> | grep GNU_SHARED` should reveal it. I'm guessing private memory usage is an easier problem. Profiling tools probably provide it. Tools like 'perf mem' and Valgrind provide the information.
