Method validate()

Validate the launcher.

Usage

crew_class_launcher_sge$validate()

Returns

NULL (invisibly). Throws an error if a field is invalid.

---

Method script()

Generate the job script.

Usage

crew_class_launcher_sge$script(name, n)

Arguments

name

Character of length 1, name of the job. For inspection purposes, you can supply a mock job name.

n

Positive integer of length 1, number of crew workers (i.e. cluster jobs) to launch in the current round of auto-scaling.

Details

Includes everything except the worker-instance-specific job name and the worker-instance-specific call to crew::crew_worker(), both of which get inserted at the bottom of the script at launch time.

Returns

Character vector of the lines of the job script.

Examples

if (identical(Sys.getenv("CREW_EXAMPLES"), "true")) {
launcher <- crew_launcher_sge(
  sge_cores = 2,
  sge_memory_gigabytes_required = 4
)
launcher$script(name = "my_job_name")
}
