Urika CS

Urika-CS nodes

Urika-CS containers can only be used on CS-Storm (clx-ai) and CS500 (clx-21) nodes.

To be able to start singularity container, the nodes have to be prepared before your batch job starts. You can do this by a resource request ('UNS=True') at your batch submission:

qsub -l select=1:node_type=clx-21:UNS=True,walltime=00:30:00 <mybatchjob>

Module singularity/3.5.2-cs-patch has some hard-coded settings for the Urika-CS stack.

Urika-CS User Manual for installed versions can be found at Cray website: v1.2UP00, v1.3UP00. Default version is currently 1.4UP00.

The only module needed to be loaded is: bigdata/analytics - it will load all dependencies and wrappers.

Quick Start

Install cuDNN

Due to license limitations you have to install cuDNN by yourself if you accept cuDNN license.

1. Download ( https://developer.nvidia.com/cudnn ) NVIDIA cuDNN for CUDA 10.0, tgz version
2. Check License you accepted during download
3. Check License in the downloaded file
4. If you accept them, upload the archive to login node

5. Extract the archive

   mkdir -p ~/cudnn/7.6.5.32/cuda10.0
   tar -xzf ~/cudnn-10.0-linux-x64-v7.6.5.32.tgz --strip-components=1 -C ~/cudnn/7.6.5.32/cuda10.0
   

6. Create a link to your cuDNN version

   ln -s ~/cudnn/7.6.5.32/cuda10.0 ~/cudnn/default
   

Reserve a node (interactive GPU job in this example)

qsub -I -l select=1:node_type=clx-ai:UNS=true -l walltime=01:00:00

Load environment

module load bigdata/analytics

Start interactive Urika-CS container (this will also deploy Spark)

start_analytics --cudnn-libs ~/cudnn/default/lib64/

# Activate Conda environment with TensorFlow (GPU)
Singularity> source activate py37_tf2.1.1_gpu

# In the latest Urika-CS image, TensorFlow is installed outside of Conda environment.
# To use TensorFlow set up PYTHONPATH with a path for corresponding version
# Use one of the commands below
## either
export PYTHONPATH=/opt/tensorflow_cpu:$PYTHONPATH
## or
export PYTHONPATH=/opt/tensorflow_gpu:$PYTHONPATH
## or
export PYTHONPATH=/opt/tensorflow_2.1.1/tensorflow_cpu:$PYTHONPATH
## or
export PYTHONPATH=/opt/tensorflow_2.1.1/tensorflow_gpu:$PYTHONPATH

Run Urika-CS container in batch mode

run_training --no-node-list --cudnn-libs ~/cudnn/default/lib64/ -n 1 -e py37_tf_gpu --tensorflow-version 2.1.1 "python test.py"

run_training here has following arguments

• --no-node-list - do not pass node list to CMD
• -n 1 - number of MPI processes, usually should correspond to the amount of reserved nodes (run_training executes: mpirun singularity ...)
• -e py37_tf_gpu - this conda environment will be activated in the container
• --tensorflow-version 2.1.1 - Specify TensorFlow version (optional). Default is version 1.x (e.g. 1.15.2)
