We've been working on a python script that measures "Resident Memory" sizes of each process at a fairly high sample rate. The initial results we've gotten from this tool are very interesting and appear fairly accurate. We are currently working to make that script work across a distributed machine by sending messages across an independent socket on each node which we open and maintain in our main python process. While this isn't terribly difficult to do, it lacks the resolution down to the data structure level that you are inquiring about so I'd be interested to hear other thoughts as well. I spent the better part of a day last wekk messing around with trying to build my own C++ allocator that kept track of each allocation/deallocation call that was made which allowed me to total up the bytes used in that particular data structure, but I didn't get it working for sets and maps which would be essential to track memory usage of many of the more interesting data structures in libMesh. For now, I've shelved that project again since we have many more important things to do but I would like to get it working at some point.
