Common abstract cluster options.

Usage

crew_options_cluster(
  verbose = FALSE,
  command_submit = as.character(Sys.which("qsub")),
  command_terminate = NULL,
  script_directory = tempdir(),
  script_lines = character(0L)
)

Arguments

verbose: Logical, whether to see console output and error messages when submitting worker.
command_submit: Character of length 1, file path to the executable to submit a worker job.
command_terminate: Deprecated on 2025-08-26 in crew.cluster version 0.3.8.9001. No longer needed.
script_directory: Character of length 1, directory path to the job scripts. Just before each job submission, a job script is created in this folder. Script base names are unique to each launcher and worker, and the launcher deletes the script when the worker is manually terminated. tempdir() is the default, but it might not work for some systems. tools::R_user_dir("crew.cluster", which = "cache") is another reasonable choice.
script_lines: Optional character vector of additional lines to be added to the job script just after the more common flags. An example would be script_lines = "module load R" if your cluster supports R through an environment module.

Value

A classed list of options.
