Nsight Tool Tutorial

This repository contains mini applications for GPU Bootcamps (Tested on NVIDIA driver 440.82)

Prerequisites:

To run this tutorial you will need a machine with NVIDIA GPU.

• Install the Docker or Singularity.
• Install Nvidia toolkit, Nsight Systems (latest version) and compute (latest version).
• The base containers required for the lab may require users to create a NGC account and generate an API key (https://docs.nvidia.com/ngc/ngc-catalog-user-guide/index.html#registering-activating-ngc-account)

Creating containers

To start with, you will have to build a Docker or Singularity container.

Docker Container

To build a docker container, run: sudo docker build -t <imagename>:<tagnumber> .

For instance: sudo docker build -t myimage:1.0 .

The code labs have been written using Jupyter notebooks and a Dockerfile has been built to simplify deployment. In order to serve the docker instance for a student, it is necessary to expose port 8000 from the container, for instance, the following command would expose port 8000 inside the container as port 8000 on the lab machine:

sudo docker run --rm -it --gpus=all -p 8888:8888 myimage:1.0

When this command is run, you can browse to the serving machine on port 8000 using any web browser to access the labs. For instance, from if they are running on the local machine the web browser should be pointed to http://localhost:8000. The --gpus flag is used to enable all NVIDIA GPUs during container runtime. The --rm flag is used to clean an temporary images created during the running of the container. The -it flag enables killing the jupyter server with ctrl-c. This command may be customized for your hosting environment.

Then, inside the container launch the Jupyter notebook assigning the port you opened:

jupyter notebook --ip 0.0.0.0 --port 8888 --no-browser --allow-root

Once inside the container, open the jupyter notebook in browser: http://localhost:8888, and start the lab by clicking on the START_profiling.ipynb notebook.

Singularity Container

To build the singularity container, run: sudo singularity build miniapp_profiler.simg Singularity

and copy the files to your local machine to make sure changes are stored locally: singularity run miniapp_profiler.simg cp -rT /labs ~/labs

Then, run the container: singularity run --nv miniapp_profiler.simg jupyter notebook --notebook-dir=~/labs

Once inside the container, open the jupyter notebook in browser: http://localhost:8888, and start the lab by clicking on the START_profiling.ipynb notebook.
