Show & Tell
1

In this episode of the Channels podcast, we talked about computing resources. Ben Sherman took us through new and upcoming runtime improvements in Nextflow, leading to better performance, fine-tuning, and simpler syntax for pipelines.

We covered:

  • Fractional CPU requests (PR #2516)
  • resourceLimits directive (to replace check_max) (PR #2911)
  • Virtual threads in Groovy (PR #3871)
  • WebAssembly runtime (a lightweight alternative to containers)

We mentioned a new blog post at the end, entitled “Automating pipeline execution with Nextflow and Tower”.
