How to use NVIDIA Nsight

Introduction to NVIDIA Nsight

NVIDIA Developer Tools are a collection of applications, spanning desktop and mobile targets, which enable developers to build, debug, profile, and develop class-leading and cutting-edge software that utilizes the latest visual computing hardware from NVIDIA. The package includes Nsight Systems, Nsight compute, and Nsight Graphics.

Installation

1. Download the required installation file

Go to the NVIDIA Developer Center - Developer Tools and download the .run package.

Select the .run package in the Nsight Systems tab for Linux installation. (It is also available for MacOS and Windows).

2. Add executions permission

cd ~/Downloads
chmod +x NVIDIA_Nsight_Graphics_2020.3.0.20148.run

3. Start the installation

Follow the instructions and settings with the command-line install wizard

./NVIDIA_Nsight_Graphics_2020.3.0.20148.run

Execution

Search in the program list the Nsight Systems link:

It can also be executed from command line with:

nsight-sys

Usage

1. Create a new project

File -> New Project

2. Select a target for profiling

3. Select data to be collected

In the following example, CUDA trace and information options are selected, but any other option such as OpenGL or MPI can be selected as well.

4. Specify program options

Insert the binary program name and the path to it:

5. Start the profiling

Click the Start button to start the profiling.

Considerations:

• The profiling process does not exit automatically and should be manually stopped.
• To avoid errors in the report the program that is being profiled should not end abruptly.
• It is preferred to measure a portion of execution time.
• The process can be stopped even if the program that is being profiled has not ended, and Nsight will generate valid results.

Report Analysis

You can refer to the following example to analyze the result in a sample application:
