Roofline model for one certain method including all submethods

[Michael_R_9]

Hello all,

Using Intel Advisor and the roof line model, I would like to assess the performance of a certain function. This function uses the Eigen library for matrix operations, where the main part of work is done.

In the output I can see my function with a relatively small self time and several Eigen functions called by my function. Now I would like to group all FLOPS and memory operations of my function together (rather than of each separate function) and use this result for the roof line model. How can I achieve this?

Related questions: I posted a question on stackoverflow [1] and in this forum I think the question [2] is related. Unfortunately, no answers yet.

Thanks a lot in advance,
Michael

As pointed out on StackOverflow, the Roofline with Call Stacks does the trick [1].
