R Documentation

Common abstract cluster options.

Description

Common abstract cluster options.

Usage

crew_options_cluster(
  verbose = FALSE,
  command_submit = as.character(Sys.which("qsub")),
  command_terminate = as.character(Sys.which("qdel")),
  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`	Character of length 1, file path to the executable to terminate a worker job. Set to `""` to skip manually terminating the worker. Unless there is an issue with the platform, the job should still exit thanks to the NNG-powered network programming capabilities of `mirai`. Still, if you set `command_terminate = ""`, you are assuming extra responsibility for manually monitoring your jobs on the cluster and manually terminating jobs as appropriate.
`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.
