how to set tmp disk variable on nextflow

I want to add the tmp disk value to my nextflow process.

CPU and memory requirements are setup, but how can I add the tmp disk value? The data is important for the scheduler (slurm) to select a suitable node.

The nextflow process header cloud be:

process TEST {
  echo true
  cpus '8'
  memory '40 GB'
  script:
    """
    """
}

This value is called in slurm tmp disk, viewable with squeue -o "%C %m %d", column MIN_TMP_DISK.

If any information is missing, please let me know.

Thanks

You can use the clusterOptions process directive with the SLURM executor. From the sbatch docs, it looks like you are looking for the --tmp option:

--tmp=[units]

Specify a minimum amount of temporary disk space per node. Default units are megabytes. Different units can be specified using the suffix [K|M|G|T].

For example:

process TEST {

    debug true

    clusterOptions '--tmp=1T'

    cpus 8
    memory 40.GB

    """
    echo "Hello world"
    """
}
