What's the advantage of this sort of thing over the trace and profile analysis tools that have been developed at least for HPC performance engineering over many years? (E.g. the BSC tools <https://tools.bsc.es/> https://tools.bsc.es/> amongst several others.) In particular, why are flame graphs preferred to the normal inclusive/exclusive views of profiles which seem more generally useful to me?
