hi, I am looking to run a native CPU and GPU bound application inside serverless and I am wondering what kind of CPU I should be targeting when compiling the executable. Right now I am building for x86-64 baseline which supports all Intel/AMD CPUs from like 2004. I'm sure runpod doesn't use CPUs this old so I could target a newer instruction set for better performance, the question is which one? Are there are any guarantees for what kind of CPUs runpod will give me? What instruction set would be safe to use?

Cool question, I don't know a lot about compilers but I do have this list of every CPU that runs our serverless fleet.
