crew_launcher_sge: *[Maturing]* Create a launcher with Sun Grid Engine (SGE)...

In crew.cluster: Crew Launcher Plugins for Traditional High-Performance Computing Clusters

Create a launcher with Sun Grid Engine (SGE) workers.

Description

Create an R6 object to launch and maintain workers as Sun Grid Engine (SGE) jobs.

  seconds_wall = Inf,
  tasks_max = Inf,
  tasks_timers = 0L,
  reset_globals = NULL,

  crashes_error = NULL,
  tls = crew::crew_tls(mode = "automatic"),
  r_arguments = c("--no-save", "--no-restore"),
  options_metrics = crew::crew_options_metrics(),
  options_cluster = crew.cluster::crew_options_sge(),
  verbose = NULL,
  command_submit = NULL,
  command_terminate = NULL,
  command_delete = NULL,
  script_directory = NULL,
  script_lines = NULL,

)

Arguments

name	Character string, name of the launcher. If the name is NULL, then a name is automatically generated when the launcher starts.
workers	Maximum number of workers to run concurrently when auto-scaling, excluding task retries and manual calls to launch(). Special workers allocated for task retries do not count towards this limit, so the number of workers running at a given time may exceed this maximum. A smaller number of workers may run if the number of executing tasks is smaller than the supplied value of the workers argument.
seconds_interval	Number of seconds between polling intervals waiting for certain internal synchronous operations to complete. In certain cases, exponential backoff is used with this argument passed to seconds_max in a crew_throttle() object.
seconds_timeout	Number of seconds until timing out while waiting for certain synchronous operations to complete, such as checking mirai::status().
seconds_launch	Seconds of startup time to allow. A worker is unconditionally assumed to be alive from the moment of its launch until seconds_launch seconds later. After seconds_launch seconds, the worker is only considered alive if it is actively connected to its assign websocket.
seconds_idle	Maximum number of seconds that a worker can idle since the completion of the last task. If exceeded, the worker exits. But the timer does not launch until tasks_timers tasks have completed. See the idletime argument of mirai::daemon(). crew does not excel with perfectly transient workers because it does not micromanage the assignment of tasks to workers, so please allow enough idle time for a new worker to be delegated a new task.
seconds_wall	Soft wall time in seconds. The timer does not launch until tasks_timers tasks have completed. See the walltime argument of mirai::daemon().
tasks_max	Maximum number of tasks that a worker will do before exiting. See the maxtasks argument of mirai::daemon(). crew does not excel with perfectly transient workers because it does not micromanage the assignment of tasks to workers, it is recommended to set tasks_max to a value greater than 1.
tasks_timers	Number of tasks to do before activating the timers for seconds_idle and seconds_wall. See the timerstart argument of mirai::daemon().
reset_globals	Deprecated on 2025-05-30 (crew version 1.1.2.9004). Please use the reset_globals option of crew_controller() instead.
reset_packages	Deprecated on 2025-05-30 (crew version 1.1.2.9004). Please use the reset_packages option of crew_controller() instead.
reset_options	Deprecated on 2025-05-30 (crew version 1.1.2.9004). Please use the reset_options option of crew_controller() instead.
garbage_collection	Deprecated on 2025-05-30 (crew version 1.1.2.9004). Please use the garbage_collection option of crew_controller() instead.
crashes_error	Deprecated on 2025-01-13 (crew version 0.10.2.9002).
tls	A TLS configuration object from crew_tls().
r_arguments	Optional character vector of command line arguments to pass to Rscript (non-Windows) or Rscript.exe (Windows) when starting a worker. Example: r_arguments = c("--vanilla", "--max-connections=32").
options_metrics	Either NULL to opt out of resource metric logging for workers, or an object from crew_options_metrics() to enable and configure resource metric logging for workers. For resource logging to run, the autometric R package version 0.1.0 or higher must be installed.
options_cluster	An options list from crew_options_sge() with cluster-specific configuration options.
verbose	Deprecated. Use options_cluster instead.
command_submit	Deprecated. Use options_cluster instead.
command_terminate	Deprecated. Use options_cluster instead.
command_delete	Deprecated on 2024-01-08 (version 0.1.4.9001). Use command_terminate instead.
script_directory	Deprecated. Use options_cluster instead.
script_lines	Deprecated. Use options_cluster instead.
sge_cwd	Deprecated. Use options_cluster instead.
sge_envvars	Deprecated. Use options_cluster instead.
sge_log_output	Deprecated. Use options_cluster instead.
sge_log_error	Deprecated. Use options_cluster instead.
sge_log_join	Deprecated. Use options_cluster instead.
sge_memory_gigabytes_limit	Deprecated. Use options_cluster instead.
sge_memory_gigabytes_required	Deprecated. Use options_cluster instead.
sge_cores	Deprecated. Use options_cluster instead.
sge_gpu	Deprecated. Use options_cluster instead.

Details

To launch a Sun Grid Engine (SGE) worker, this launcher creates a temporary job script with a call to crew::crew_worker() and submits it as an SGE job with qsub. To see most of the lines of the job script in advance, use the script() method of the launcher. It has all the lines except for the job name and the call to crew::crew_worker(), both of which will be inserted at the last minute when it is time to actually launch a worker.
