Introduction

KNIME Analytics Platform is the open source software for creating data science applications and services.
KNIME stands for KoNstanz Information MinEr.

Installed version

The currently installed version is available on the environment hpc-env/6.4:

KNIME/3.6.2

KNIME Module

If you want to find out more about KNIME on the HPC Cluster, you can use the command

module spider KNIME

This will show you basic informations e.g. a short description and the currently installed version.

To load the desired version of the module, use the command, e.g.

module load  KNIME

Always remember: this command is case sensitive!

Using KNIME on the HPC Cluster

Basically, you have two options to use KNIME on the HPC cluster: 1) you can start KNIME within a job script and execute a prepared workflow or 2) you can use the SLURM Cluster Execution from your local work station to offload selected nodes from your workflow to the cluster. Both option are described briefly below.

Using KNIME with a job script

This approach is straight-forward once you have prepared a workflow for the execution on the cluster. That means you need to copy all the required files to a directory on the cluster (the worflowDir). After that you need to write a job script which calls KNIME and runs your workflow. A minimal example is

#!/bin/bash

knime -nosplash -application org.knime.product.KNIME_BATCH_APPLICATION -workflowDir="$HOME/knime-workspace/Example Workflows/Basic Examples/Simple Reporting Example"
