sge

This profile configures Snakemake to run on (Sun) Grid Engine.

Setup

Deploy profile

To deploy this profile, run

mkdir -p ~/.config/snakemake
cd ~/.config/snakemake
cookiecutter https://github.com/drjbarker/snakemake-gridengine.git

Then, you can run Snakemake with

snakemake --profile sge ...

Cookiecutter options

• profile_name : A name to address the profile via the --profile Snakemake option.
• cluster_config : Path to a YAML or JSON configuration file analogues to the Snakemake --cluster-config option. This is also used to define custom resources on the SGE cluster.

Default snakemake arguments

Default arguments to snakemake maybe adjusted in the <profile path>/config.yaml file.

Parsing arguments to SGE (qsub)

Arguments are overridden in the following order, aliases are also defined and can be defined :

1. QSUB_DEFAULTS in sge-submit.py
2. Profile cluster_config file __default__ entries
3. Snakefile threads and resources (time, mem)
4. Profile cluster_config file entries
5. --cluster-config parsed to Snakemake (deprecated since Snakemake 5.10)

Resource mapping

To allow more expressive resource requests we map some simple names to the SGE options and resources. These can be used for example in cluster.yaml to make the configuration simpler to read.

Notes

Custom SGE resources can be specified in __resources__ only in the profile folder (i.e. any __resources__ in a local --cluster-config cluster.yaml will be ignored, but you can request the resources defined in the global profile). Custom resources are specified as a YAML dictionary where the key is the resource name as defined in SGE and the values are any aliases you want to use for this resource. The key will always be avaiable as a name even if you don't specifiy it as an alias. If a key already exists in the resource list the the aliases are just appended to that resource.

For example:

__resources__:
  coproc_v100: 
    - "gpu"
    - "nvidia_gpu"

Allows you to request with coproc_v100=1, gpu=1 or nvidia_gpu=1 in the cluster config files or snakemake rule resources all of which will actually set -j coproc_v100=1 for qsub.

Memory (s_vmem, h_vmem and aliases) must be given in gigabytes.
