You can allocate whatever you want > from virtual memory, it is not "used" until it's touched. Yes, I do. So do you suggest using RES as a better indicator of memory footprint? The program in question processes large 3D images via vtk, and I'd like to measure its memory usgae with different parameter configurations as the maximum amount of memory acquired during execution. Since SIZE often happens to be larger than RES, and increase more during execution, I thought of using it as an indicator of memory footprint. ~Razmig
