Could you build this?
No Developing a low-overhead continuous CUDA profiler using hardware PC sampling requires elite systems and GPU internals expertise interfacing with CUPTI and the Linux kernel.
What it would actually take: The architecture involves an in-process or daemon agent (like Parca Agent) interfacing with the low-level NVIDIA CUPTI (CUDA Profiling Tools Interface) Activity APIs to hook into GPU hardware counters and warp schedulers. It requires managing circular shared-memory ring buffers, dynamic sampling frequency throttling to avoid execution overhead, and kernel-space eBPF integration to correlate host threads with GPU kernels. Achieving this demands deep knowledge of NVIDIA hardware architecture, CUDA runtime internals, and C/eBPF systems programming.
Discussion
6 comments analyzed.
Concerns raised: PC sampling utility unclear for performance debugging, Performance varies with data characteristics (sorted vs randomized), Kernel behavior differs between dev and production environments
