about: Three new cluster configurations for the GIGA and CÉCI.

Please follow these steps before submitting your PR:

• If your PR is a work in progress, include [WIP] in its title
• Your PR targets the master branch
• You've included links to relevant issues, if any

Steps for adding a new config profile:

• Add your custom config file to the conf/ directory
• Add your documentation file to the docs/ directory
• Add your custom profile to the nfcore_custom.config file in the top-level directory
• Add your custom profile to the README.md file in the top-level directory
• Add your profile name to the profile: scope in .github/workflows/main.yml
• OPTIONAL: Add your custom profile path and GitHub user name to .github/CODEOWNERS (**/<custom-profile>** @<github-username>)

Summary

This PR adds the three following configuration profiles:

• giga to use with GIGA cluster
• ceci_dragon2 to use with Dragon2
• ceci_nic5 to use with NIC5

Hi @MartinGrignard !

Thanks for the PR! I the meantime please also join the nf-core github orgnaisation with instructions here: https://nf-co.re/join

So we don't have to wait someone to manually use the tests and also get the code owners file to work :)

Does singularity also need to be laoded, or is this available by default?

Also the dragon2 config doesn't specify a singualrity cache directory, if users need to do this manually maybe document to specify this with the nextflow NXF_SINGULARITY_CACHEDIR (https://nextflow.io/docs/latest/reference/env-vars.html) so they at least can cache on a per-user basis

[MartinGrignard]

Yes, the singularity command is available by default on both CÉCI clusters (Dragon2 and NIC5).

Since there is no shared directory that I am aware of on those clusters, is this recommended to still specify it to something like ${HOME}/.cache/singularity? Or is it okay to leave it empty so that the system uses its default value?

[jfy133]

It is recommended to specify a directory with NXF_SINGULARITY_CACHE_DIR as the 'default' by Nextflow is to pull the images into the work/ directory, which is run specific. On the next run where -w is somewhere else it'll download the images again

[MartinGrignard]

Thanks for the information, I added a default cache directory (for consistency across all users). If, in the future, a shared directory is created on these clusters, I'll document how to use it/switch to it.

Hi @MartinGrignard !

Thanks for the PR! I the meantime please also join the nf-core github orgnaisation with instructions here: https://nf-co.re/join

So we don't have to wait someone to manually use the tests and also get the code owners file to work :)

I just posted my request on the #github-invitations channel of the slack workspace.

[jfy133]

@MartinGrignard you'll need to accept the invitation by the email or by going to https://github.com/orgs/nf-core/

[jfy133]

One further optimisation you could do is collapse the multiple params blocks into one (the info and old max_* resource limitations), but not a blocker
