bundle — Job Bundling

The bundle task groups multiple zppy tasks into a single SLURM job script. This is useful for running many lightweight tasks together on a single node, avoiding scheduler overhead and resource waste.

When a task specifies bundle = "<name>" in its configuration, it will be included in the named bundle. The bundle itself is defined in a [bundle] section.

Note

Bundle parameters (e.g., walltime, nodes) are taken from the first task added to the bundle, or from the [bundle] section itself. The active parameter in [bundle] always overrides the [default] value and defaults to True.

Configuration example

[bundle]
  [[long_jobs]]
  walltime = 08:00:00
  nodes = 1

[climo]
  [[atm_monthly_180x360_aave]]
  bundle = long_jobs
  years = 1:100:20

[ts]
  [[atm_monthly_180x360_aave]]
  bundle = long_jobs
  years = 1:100:10
