defineSequentialEventNumbers()

findPlaceInTask()

python.RunDependentMCTaskIterator.findPlaceInTask	(		jobnumber,

 Get the 'i'th job in the task, where each job tries to do maxEvents events.
The 'force_new' flag in the LB list ends the task before that LB, ignoring maxEvents.
Returns a taskIterator. Can raise StopIteration, so you should nest in try.

Calculate the specific configuration of the current job in the digi
task. Try to make each fragment utilize the same amount of CPU and
Cache resources.  Exploits the fact that the task when sorted by
mu value will have long finishing pieces near the beginning and
short pieces near the end.  A more even solution is obtained by
pairing chunks of maxEvents/2 from the beginning and end of the
sorted task.
