Functionality Test

This repository contains a functionality test with modified script files:

• runExperimentFromRemote.sh
• runExperiments.sh
• setup.sh

Overview

The experiments are adjusted so they do not execute over a network.

• No Ceph or NFS is created.
• Instead, the local storage maps into the mem disk and the shared storage onto the hosts physical disk.
• However, the examples are pretty small and no performance improvements might be observed — this is purely a functionality test.

Additionally, the repository includes a kind-config.yaml file for a minimal kind configuration.
Ensure kind is installed on your machine before proceeding.
Installation Guide

Running the Functionality Test

We recommend executing setupKind.sh line by line to set up the environment.

Adjusting RAM Disk Size

If your machine cannot allocate ~15GB to the RAM disk, you can reduce this part in all nextflow.config files within the folders:

• allIntoOne
• chain
• fork
• group
• groupMultiple

Modify the following parameters:

params {
    minSizeGB = 0.1
    maxSizeGB = 0.2
    numberOfTasks = 20
}

Running Experiments

The functionality was confirmed on Ubuntu 22.04.

With WOW and CWS:

bash runExperimentFromRemote.sh ceph

With the Original Nextflow:

bash runExperimentFromRemote.sh orig-ceph

Experiment Results

If you did not modify the kind-config.yaml, the results are stored at: /tmp/kind/data/shared-experiments as described in the Results and Evaluation repository.

This directory also contains the logs of the current run.
