void setFlops(double f)
Set the number of f of the task (to be used only in very specific cases in which it is guaranteed that changing a task’s work after that task has been created is a valid thing to do)
- Parameters
f – the number of f
Set the task’s parallel model.
- Parameters
model – a parallel model
