Setup
- Install snakemake via mamba/conda (see https://snakemake.readthedocs.io/en/stable/getting_started/installation.html)
- In the working folder create a snakemake environment with
mamba activate snakemake</cpde> - Install the cluster-generic tool to submit snakemake files to a cluster from pip with
pip install snakemake-executor-plugin-cluster-generic - Create a generic profile in ~/.config/snakemake/testprofile/config.yaml such as:
executor: slurm
jobs: 100
default-resources:
mem_mb: max(1.5 * input.size_mb, 100)
account: <ACCOUNT_NAME>
partition: <PARTITION NAME>
set-threads:
myrule: max(input.size_mb / 5, 2)
set-resources:
myrule:
mem_mb: attempt * 200
Executing a Snakefile Workflow
- Create a Snakefile (see
- You can over-ride resources with that flag otherwise it will use the values in testprofile
- Run the Snakefile with this command
snakemake --profile testprofile -j 1 --executor cluster-generic --cluster-generic-submit-cmd "batch" ...
