Intel AI Flame Graphs is now open-source! Optimize GPU performance for AI, gaming & HPC with advanced flame graph profiling. Supports Intel Max Series, Arc Battlemage & Lunar Lake Xe2. Learn more & download on GitHub.
Intel has open-sourced its powerful AI Flame Graphs tool, initially developed for Intel Tiber AI Cloud, to provide deep insights into AI accelerator and GPU performance profiling.
This move unlocks hardware-level diagnostics for developers, researchers, and enterprises working with Intel Data Center GPUs, Arc Battlemage, and Lunar Lake Xe2 integrated graphics.
What Is AI Flame Graphs?
AI Flame Graphs is an advanced profiling tool that visualizes GPU execution metrics via flame graphs, offering granular insights into:
EU stalls (Execution Unit bottlenecks)
CPU stack traces
GPU kernel performance
Hardware sampling data
Originally designed for Intel Max Series GPUs, the tool now supports Battlemage discrete GPUs and Lunar Lake’s Xe2 architecture, making it a versatile solution for AI and traditional graphics workloads.
Key Features & Technical Requirements
To leverage AI Flame Graphs, users need:
✔ Kernel driver modifications
✔ Frame pointers enabled (for system libraries & compiled code)
✔ eBPF support (for extended Berkeley Packet Filter integration)
Unlike proprietary alternatives, Intel’s open-source approach allows customization for AI training, inference, and real-time rendering optimization.
Why This Matters for Developers & Enterprises
Optimize AI workloads – Identify inefficiencies in PyTorch, TensorFlow, and CUDA pipelines.
Boost GPU utilization – Pinpoint hardware stalls and kernel bottlenecks.
Cross-platform compatibility – Supports data center GPUs, gaming GPUs, and integrated graphics.
"AI Flame Graphs bridges the gap between hardware and software profiling, offering unprecedented visibility into GPU execution." — Brendan Gregg, Intel Engineer
How to Get Started with AI Flame Graphs
The project is now Apache 2.0 licensed and available on GitHub (intel/iaprof). For a deep dive, check out Intel’s official blog post by Brendan Gregg.
