Yeah, I guess I need to spend more time with Massif. I tried it last week
for the first time as well and was overwhelmed by the amount of output.
From what I've seen just scanning over the output is a detailed log of
when and how much memory is used. Is there a way to flip that tree
upside-down
Here is a sample of what massif can provide:
#---
snapshot=76
#---
time=34259946158
mem_heap_B=81869326
mem_heap_extra_B=2917770
mem_stacks_B=0
heap_tree=detailed
n7: 81869326 (heap allocation functions) malloc/new/new[], --alloc-fns, etc.
n3: 31253406 0xF0712EE: PetscMallocAlign

I'd certainly really like to hear thoughts on this

Hi,
Is there a way to get the memory footprint of individual datastructures
in the library? For example, if I want to know the size of a DofMap, and a
Mesh?
Thanks,
