Hello to the community once more.
My concern is if I can use DHAT and MASSIF to measure the external
fragmentation of my application which is using the default Ubuntu ptmalloc2
allocator.
I have found a several formulas on the paper The Memory Fragmentation
Problem : Solved?, most of them use the live memory, maximum amount of
memory used by the allocator, maximum amount requested by the program.
How can I interpret the DHAT and MASSIF output to get those values?
In case you have any other suggestion for another formula please let me
know.
I am aware that the most common way is to find the largest free contiguous
block in heap, relative to the total heap amount. But I have not figured
out how to get this measurement.
If you have any information or tip it will be a real great help.
Thank you everyone in advance
