fcoll/dynamic_gen2: Adjustment of displacement index in collective write

Просмотр исходного кода 
Within the shuffle iteration, the aggregators have to set a displacement array needed to receive data from other processes. The array had 1 extra element. We adjust the displacement index to match the number of elements.
