Multiple Instances without a Priori Run-Time Knowledge

From BrickWikiTwo
Jump to: navigation, search


  • N multiple instances of an activity run concurrently
  • N is unknown until some late point in the processing of the instances
  • but not at the design time of the process and not before the processing of the instances runs
  • the number of instances is evaluated as late as possible
  • e.g. the stopping condition is evaluated in the loop itself
  • all running instances of the activity join before continuing in the process flow
  • all instances of an activity are run in parallel and synchronised
