TPacketizerUnit Class Reference

This packetizer generates packets of generic units, representing the number of times an operation cycle has to be repeated by the worker node, e.g. the number of Monte carlo events to be generated. Packets sizes are generated taking into account the performance of worker nodes, based on the time needed to process previous packets, with the goal of having all workers ending at the same time.
