I just really need (actually, would like) to get a *rough* idea of how memory is fragmented - if I have a HPC application that allocates a large amount of memory, how fragmented is that in physical ram. It's not the end of the world if I can't, but it would definitely be helpful (for a number of reasons that are outside the scope of my question)... I'm really only concerned with one or two processes If you can make some minor changes to the application and write an I/ O kit driver, you could easily have the app issue an I/O against the driver and then have the driver use the IOKit functionality to do the virtual->physical mapping. That avoids trying to go backwards, which is what you're describing there. This email sent to site_archiver@lists.apple.com
