I don't know anything about the HdrHistgram you're referring to. Would you care to elaborate? We have a histogram implementation in HPX (https://github.com/STEllAR-GROUP/hpx/blob/master/hpx/util/histogram.hpp) which is currently used for a special performance counter in the parcel (message) coalescing layer. But this does not have to be used for a general purpose counter.
