Import system images

System-level container images are used by all users. You can obtain images from Lenovo salesperson or import images into LiCO as system-level container images. This section describes how to create and import system-level container images.

Image bootstrap files

Download image_bootstrap.zip from https://hpc.lenovo.com/lico/downloads/6.1/images/host/image_bootstrap.zip, image_bootstrap.zip includes the following singularity bootstrap(definition) files, then we can use it to create images.

Create images

Step 1. Prepare a build node with a minimum storage of 100 GB.

Notes:

This node should have the same OS version and singularity version with the nodes in the cluster.
If you want to create GPU images, this node should have the same GPU and GPU driver as nodes in the cluster.
To use images related to the MKL function, ensure that these images are created on a machine with the same CPU architecture.

Step 2. To the build node, ensure that squashfs-tools, libarchive, and make are installed.

Step 3. To the build node, upload the compressed image bootstrap file you obtained which named image_bootstrap.zip. For example, upload the compressed package to the new directory /opt/images. If the new directory cannot be found, create it manually. Note that both this new directory and /var/tmp cannot be an NFS mount.

Step 4. To the build node, run the following commands to extract the compressed package.


xxxxxxxxxx
cd /opt/images
unzip image_bootstrap.zip

Step 5. To the build node, do one of the following to create image. The created image file is in the dist folder of the current directory.

Run the following commands to create all images at once:


xxxxxxxxxx
cd /opt/images/image_bootstrap
make all

Run the following commands to create a group images at once:


xxxxxxxxxx
cd /opt/images/image_bootstrap
make caffe
make intel-caffe
make intel-python
make tensorflow
make mxnet
make neon
make chainer
make letrain
make jupyter
make pytorch
make scikit

Notes: Check the network when one of the following errors is displayed:

ERROR MANIFEST_UNKNOWN: manifest unknown
ReadTimeoutError: HTTPSConnectionPool(host='files.pythonhosted.org', port=443): Read timed out.
urllib2.URLError: <urlopen error [Error 104] Connection reset by peer>

Import images into LiCO as system-level images

Step 1. Copy the created images to the management node.

For example, copy the images to directory /opt/images. Note that both this directory and /var/tmp cannot be an NFS mount

Step 2. Run the following commands to import images into LiCO:


cd /opt/images
lico import_image caffe-cpu caffe-1.0-cpu.image caffe
lico import_image caffe-gpu caffe-1.0-gpu-cuda92.image caffe
