4. AI Flame Graphs 2025-01-20

   tags: artificial-intelligence, intel, performance/profiling, programming/c++, programming/python, visualization

   [ permalink ]

   AI developers think about their bit of code, but with AI Flame Graphs they can now see the entire stack for the first time, including the HW, and many layers they don't usually think about or don't know about. It basically looks like a pile of gibberish with their code only a small part of the flame graph.

   This reaction is similar to people's first experiences with CPU flame graphs, which show parts of the system that developers and engineers typically don't work on, such as runtime internals, system libraries, and kernel internals.
