--- Comment #8 from vincenzo Innocente <vincenzo.innocente at cern dot ch> --- My understanding of the gather latency is that it essentially corresponds to a load per cacheline: fast if all items are closeby, slower than scalar loads if items are all in different cachelines. Not sure how this can be turned in a "cost model"
