I'm writing to propose a project that aims to add roofline support to the perf tool. During my internship, I've gained significant experience in roofline analysis. This project involves incorporating micro-benchmarks to generate roofline data, initially using the Original roofline model outlined in the following paper: [paper](https://people.eecs.berkeley.edu/~kubitron/cs252/handouts/papers/RooflineVyNoYellow.pdf). We can later explore incorporating cache-aware rooflines [paper](https://www.inesc-id.pt/ficheiros/publicacoes/9068.pdf). For testing and comparison, I have access to a laptop with an Intel 10300H processor. This allows for comparison with tools like Intel Advisor, Likwid, and other open source toolkits. I believe your mentorship would be invaluable in guiding me through this project. I'd like to explore the perf codebase to gain a better understanding of its structure. I would be grateful for any advice you may have regarding exploring the codebase, suggesting initial "easy hacks" or beginner-friendly issues to contribute to, and pointing me towards appropriate communication channels within the perf community. Thank you for your time and consideration.
