Hello,

I am using **Nsight Compute (GUI)** and I see that I can generate the **Floating Point Operations Roofline (FP32)** directly in the graphical interface. However, I want to be able to obtain the **raw data** behind this graph, including:

1. **Application characterization metrics** : kernel FLOPs, SM cycles, L1/L2/DRAM traffic.

2. **Roofline maximum ceiling points** : the peak limits that define the Roofline “breakpoints” for FP32.

My questions are:

- Is there a way to **export these values directly from `ncu` (CLI) or from the GUI** to CSV, JSON, or another readable format?

- If I cannot get the exact graph points, is it possible to **obtain the underlying metrics** for both the kernel and the GPU peak ceilings, even if I need to process them myself afterward?

My goal is to be able to **plot the complete FP32 Roofline** , including both my kernel data and the GPU peak ceilings, for a convolution kernel on Orin, without relying on the GUI visualization.

Thanks in advance!

Hi,

Yes, please find the document below for more information:

In case anyone needs it, the parameters and formulas required to calculate the points shown in the Roroline graph are displayed in the additional information when selecting a point at least in the 2025 version of NVIDIA Nsight Compute.
