ExecutionContextTasks

scala.collection.parallel.ExecutionContextTasks
trait ExecutionContextTasks extends Tasks

This tasks implementation uses execution contexts to spawn a parallel computation.

As an optimization, it internally checks whether the execution context is the standard implementation based on fork/join pools, and if it is, creates a ForkJoinTaskSupport that shares the same pool to forward its request to it.

Otherwise, it uses an execution context exclusive Tasks implementation to divide the tasks into smaller chunks and execute operations on it.
