Nextflow enables scalable and reproducible scientific workflows, often using software containers. It allows the adaptation of pipelines written in the most common scripting languages. It can be particularly useful in high-throughput domains such as bioinformatics or radio-astronomy.

process bigTask {
  label 'gpu'
