UConn HPC profile Configuration
nf-core pipelines have been successfully configured for use on the UConn HPC cluster at Xanadu.
To use the xanadu profile, run the pipeline with -profile xanadu. This will download and apply xanadu.config which has been pre-configured for the UConn HPC cluster “Xanadu”. Using this profile, all Nextflow processes will be run within singularity containers, which can download and convert from docker containers when necesary.
A Nextflow module is available on the Xanadu HPC cluster, to use run module load nextflow or module load nextflow/<version> prior to running your pipeline. If you are expecting the NextFlow pipeline to consume more space than is available, you can set the work directory to /scratch/<userid> which can handle 84.TB with export NXF_WORK=/scratch/<userid>. CAUTION make sure to remove items from this directoy, it is not intended for long-term storage.
