If you need more than 512 histograms, I think you are doing something wrong. |

Problem
SH histograms scale as
nCent * nKt * (2 * nJM + 2)and overflow the512-histogram limit of a single
HistogramRegistry.Solution
PairHistManager::init()takes an optional pool of registries for SHhistograms and assigns each (cent, kT) cell to one with room. Builders
forward separate pools for same-event and mixed-event.
