Docker Containers Usage

Page build up from the bottom to top. We're not making a traditional “MPI” docker integration with our scheduler. We'll see what usage patterns will emergence and go from there. I can help with workflow. If more containers are desired please let me know which ones to pull.

If users want to run web enabled applications in the container one simple workflow would be to submit a job that reserves a GPU then loops checking a lock file until removed. Then ssh to the node and access the application via firefox http://localhost:PORT/. For example DIGITS and JupyterLab described below.

Readings

Interesting reads…

Scheduler Runs

Next add to the script the scheduler syntax that is needed. Request a gpu resource gpu4, memory and submit jobs. Example is located at /home/hmeij/jobs/docker/run.docker. Notice that we use nvidia-docker External Link. Nvidia-Docker is basically a wrapper around the docker CLI that transparently provisions a container with the necessary dependencies to execute code on the GPU.

#!/bin/bash
# submit via 'bsub < run.docker'
rm -f out err
#BSUB -e err
#BSUB -o out
#BSUB -q exx96
#BSUB -J "RTX2080S docker"

#BSUB -n 1
#BSUB -R "rusage[gpu4=1:mem=6288],span[hosts=1]"

# should add a check we get an integer back in the 0-3 range
gpuid="` gpu-free | sed "s/,/\n/g" | shuf | head -1 ` "
echo ""; echo "running on gpu $HOSTNAME:$gpuid"; echo ""

NV_GPU=$gpuid \
nvidia-docker run --rm -u $(id -u):$(id -g) \
-v /$HOME:/mnt/$USER \
-v /home/apps:/mnt/apps \
-v /usr/local:/mnt/local \
nvcr.io/nvidia/tensorflow:19.09-py2 python \
/mnt/$USER/jobs/docker/benchmarks-master/scripts/tf_cnn_benchmarks/tf_cnn_benchmarks.py \
--num_gpus=1 --batch_size=64 \
--model=resnet50 \
--variable_update=parameter_server
# or run_tests.py

To make the imports work edit that python file

import sys
sys.path.insert(0, '/mnt/hmeij/jobs/docker/benchmarks-master/scripts/tf_cnn_benchmarks/')

GPU Runs

We put the tensorflow benchmark example in a script. It will find a free gpu, set it in a environment variable NV_GPU and then run the tensorflow application on the GPU allocated.

# execute script
[hmeij@n79 docker]$ ./run.docker

running on gpu n79:3   <--------- this is the physical gpu id
 
# tensorflow starts up

Simple Runs

Some simple interactive test runs. Map your home directory from the host inside the container, I choose /mnt but it can go anywhere but /home … Also set up your uid/gid because the container will run as “root” in user namespace.

# probe uid:gid inside container
[hmeij@n79 ~]$ nvidia-docker run --rm -v /$HOME:/mnt/$USER \
-u $(id -u):$(id -g) nvcr.io/nvidia/cuda:10.0-devel id

uid=8216 gid=623 groups=623

# probe home directory inside container
[hmeij@n79 ~]$ nvidia-docker run --rm -v /$HOME:/mnt/$USER \
-u $(id -u):$(id -g) nvcr.io/nvidia/cuda:10.0-devel df /mnt/hmeij

Pull Images

Pull more images from the Nvidia Gpu Cloud Catalog. There are also models. As you can tell, not all containers applications are up to date. Only pulled on node n79, not expecting any usage. It is nice to pull esoteric software like the deep learning stack (digits, tensorflow, pytorch, caffe, rapidsai).

JupyterLab

The Rapids container and Notebook Server hide in the rapidsai:cuda10.0 container, also an interactive browser enabled application. Again, not sure how we would use it but here is how to start it. JupyterLab is a next-generation web-based user interface for Project Jupyter. External Link. Project Jupyter exists to develop open-source software, open-standards, and services for interactive computing across dozens of programming languages. External Link

[hmeij@n79 ~]$ docker run  --runtime=nvidia --rm -it \
-p 8888:8888 -p 8887:8887 -p 8886:8886 \
nvcr.io/nvidia/rapidsai/rapidsai:0.9-cuda10.0-runtime-centos7

Any user can connect once started. Here is what it looks like. Note: the –rm flags means stop and remove container when done.

Digits

The NVIDIA Deep Learning GPU Training System (DIGITS) puts the power of deep learning into the hands of engineers and data scientists. DIGITS can be used to rapidly train the highly accurate deep neural network (DNNs) for image classification, segmentation and object detection tasks. External Link

DATE=$( date +%N )  # nanoseconds unique id

docker run --runtime=nvidia -e NVIDIA_VISIBLE_DEVICES="0,1,2,3" \

Digits looks like this. We'll probably never use it and can be restarted. Note file system mapping of hosts /data/datasets to container /opt/datasets location. It also grabs all GPUs. Log in as dockuser.

Portainer

Portainer is a simple management solution for Docker which allows browser access on http://localhost:9000 with admin credentials. We'll probably never use this but use the command line instead (docker ps, docker kill, etc).

DATE=$(date +%N)  # nanoseconds as unique id
docker run --name portainer-$DATE-0 -d -p 9000:9000 \
-v "/var/run/docker.sock:/var/run/docker.sock" --restart=always \
portainer/portainer

Portainer looks like this.

What's Running?

  • Docker Version 19.03.5
  • NVIDIA-Docker2 2.2.2-1

Video was “onboard” which means Gnome/X jump on first GPU scanned in pci bus (not always the same one!). We set configuration multi-user.target so we have video on VGA rather than GPU. The BIOS onboard video enabled setting was not changed, for now.
