nf-core/configs: KU Leuven/UHasselt Tier-2 High Performance Computing Infrastructure (VSC)

NB: You will need an account to use the HPC cluster to run the pipeline.

  1. Install Nextflow on the cluster
conda create --name nf-core python=3.12 nf-core nextflow
Note

A nextflow module is available that can be loaded module load Nextflow but it does not support plugins. So it’s not recommended

  1. Set up the environment variables in ~/.bashrc or ~/.bash_profile:
Note

If you have access to dedicated nodes, you can export these as a command separated list. These queues will only be used if specified task requirements are not available in the normal partitions but they are available in dedicated partitions. AMD is considered a dedicated partition.

export SLURM_ACCOUNT="<your-credential-account>"
 
# Comma-separated list of available dedicated partitions (if any)
# For example: export VSC_DEDICATED_QUEUES="dedicated_big_bigmem,dedicated_big_gpu"
export VSC_DEDICATED_QUEUES="<available-dedicated-partitions>"
 
# Needed for running Nextflow jobs
export NXF_HOME="$VSC_SCRATCH/.nextflow"
export NXF_WORK="$VSC_SCRATCH/work"
 
# Needed for running Apptainer containers
export APPTAINER_CACHEDIR="$VSC_SCRATCH/.apptainer/cache"
export APPTAINER_TMPDIR="$VSC_SCRATCH/.apptainer/tmp"
export NXF_CONDA_CACHEDIR="$VSC_SCRATCH/miniconda3/envs"
 
# Optional tower key
# export TOWER_ACCESS_TOKEN="<your_tower_access_token>"
# export NXF_VER="<version>"      # make sure it's larger then 24.10.1
Warning

The current config is setup with array jobs. Make sure nextflow version >= 24.10.1, read array jobs in nextflow you can do this in

export NXF_VER=24.10.1
  1. Make the submission script.

NB: you should go to the cluster you want to run the pipeline on. You can check what clusters have the most free space using following command sinfo --cluster wice|genius.

$ more job.pbs
#!/bin/bash -l
#SBATCH --account=...
#SBATCH --chdir=....
#SBATCH --partition=batch_long
#SBATCH --nodes="1"
#SBATCH --ntasks-per-node="1"
 
# module load Nextflow # does not support plugins
conda activate nf-core
 
nextflow run <pipeline> -profile vsc_kul_uhasselt,<CLUSTER> <Add your other parameters>

NB: You have to specify your credential account, by setting export SLURM_ACCOUNT="<your-credential-account>" else the jobs will fail!

Here the cluster options are:

  • genius
  • genius_gpu
  • wice
  • wice_gpu
  • superdome

NB: The vsc_kul_uhasselt profile is based on a selected amount of SLURM partitions. The profile will select to its best ability the most appropriate partition for the job. Including modules with a label containing gpuwill be allocated to a gpu partition when the ‘normal’ genius profile is selected. Select the genius_gpu or wice_gpu profile to force the job to be allocated to a gpu partition. NB: If the module does not have accelerator set, it will determine the number of GPUs based on the requested resources.

Use the --cluster option to specify the cluster you intend to use when submitting the job:

sbatch --cluster=wice|genius job.slurm 

All of the intermediate files required to run the pipeline will be stored in the work/ directory. It is recommended to delete this directory after the pipeline has finished successfully because it can get quite large, and all of the main output files will be saved in the results/ directory anyway.

  1. Optional use nf-co2footprint

You can monitor the CO2 usage of your pipeline using the nf-co2footprint plugin using a nextflow version =>24.10.6. Monitoring the CO2 usage is fully optional and will only be activated when running the following command-line.

nextflow run <pipeline> -profile <CLUSTER> -plugins nf-co2footprint@1.0.0 --outdir your_output_folder <Add your other parameters>

/*
 * Queue Selection Logic for HPC Environments
 * ===========================================
 * Each process directive closure below contains inlined queue selection logic
 * for compatibility with Nextflow config parser v2 (no top-level def allowed).
 *
 * Constants used throughout:
 *   TIME_THRESHOLD          = 72.h   (threshold for long-running jobs)
 *   MEMORY_THRESHOLD_GENIUS = 175.GB (bigmem threshold for GENIUS)
 *   MEMORY_THRESHOLD_WICE   = 239.GB (high-memory threshold for WICE)
 *
 * Queue selection rules:
 *   GENIUS CPU:  memory >= 175GB → bigmem/bigmem_long; else → batch/batch_long
 *   GENIUS GPU:  memory >= 175GB → gpu_v100; else → gpu_p100/amd (with dedicated queue checks)
 *   WICE CPU:    memory >= 239GB → bigmem,hugemem (time capped at 72h); else → batch/batch_icelake
 *   WICE GPU:    memory >= 239GB → gpu_h100; else → gpu_a100,gpu (time capped at 72h unless dedicated)
