> We ran a job with {{slotmanager.number-of-slots.max = 10}},
> {{taskmanager.numberOfTaskSlots = 10}} and {{taskmanager.memory.process.size:
> 24000m}}. The resources of the cluster are sufficient, but no TaskManager can
> be allocated. It seems that there is a problem with the calculation logic of
> {{SlotManagerConfiguration#getMaxTotalMem}}. Due to the rounding down of
> division, the calculated {{MemorySize}} is too small.
