CloudSubmit

CloudSubmit[expr]

submits expr for immediate asynchronous cloud evaluation.

CloudSubmit[ScheduledTask[expr,spec]]

submits a task to evaluate expr in the cloud on the schedule defined by spec.

Details and Options

  • CloudSubmit[expr] returns TaskObject[…] to represent the task it creates.
  • Possible values of spec are those supported by the ScheduledTask.
  • The following options can be given:
  • HandlerFunctions<||>how to handle generated events
    HandlerFunctionsKeysAutomaticparameters to supply to handler functions
    NotificationFunction Automatichow to provide notifications about the task
    CloudBase $CloudBasethe base of the cloud to use
    IncludeDefinitionsTruewhether to automatically include dependencies
  • During the execution of the task, the following events can be generated:
  • "TaskStarted"task is started
    "FailureOccurred"task could not be started
    "ScheduleTriggered"scheduled task evaluation is beginning
    "MessageGenerated"evaluation generated a message
    "PrintOutputGenerated"evaluation generated print output
    "ResultReceived"evaluation generated a result
    "ScheduleExecuted"scheduled task evaluation is executed
    "TaskStatusChanged"task status changed
    "TaskFinished"task is completely finished
    "TaskRemoved"task is being removed
  • With the specification HandlerFunctions-><|…,"eventi"->fi,…|>, fi[assoc] is evaluated whenever eventi is generated. The elements of assoc have keys specified by the setting for HandlerFunctionsKeys.
  • Possible keys specified by HandlerFunctionsKeys include:
  • "EvaluationExpression"expression being evaluated
    "EvaluationResult"result of the evaluation
    "Failure"failure object generated if task failed
    "MessageOutput"content of message generated
    "PrintOutput"content of print output generated
    "Task"the object representing the task
    "TaskStatus"the status of the task
    "TaskType"type of the task
    "TaskUUID"unique task identifier
    "EventName"the name of the event being handled
  • The expression to evaluate is returned wrapped in Hold.
  • For scheduled tasks, the following additional keys can be specified:
  • "Schedule"task schedule specification
    "RunInterval"interval between task runs
    "PreviousRunCount"number of times the task has already run
    "RemainingRunCount"number of times the task still has to run
    "TotalRunCount"total number of times the task is scheduled to run
  • The cloud evaluation specified by CloudSubmit is subject to the user's time and memory limits for tasks in the cloud.
  • With IncludeDefinitions->True, definitions required for the evaluation of expr will automatically be sent to the cloud through CloudSubmit.
  • With IncludeDefinitions->False, definitions required for the evaluation of expr must be loaded and evaluated explicitly during the evaluation of expr.
