WaitNext

WaitNext[{eid1, eid2, ...}]
waits until the first evaluation represented by any of the finishes, then returns its result, the corresponding , and the list of remaining .

DetailsDetails

  • The are EvaluationObject expressions obtained by submitting expressions for concurrent evaluation using ParallelSubmit.
  • WaitNext[{eid1, eid2, ...}] returns a list , where res is the result of the finished evaluation, eid is its EvaluationObject, and eids is the list of remaining evaluations.
  • The last element in the list produced by WaitNext is suitable for another call to WaitNext.
