RooFit::MultiProcess::ProcessTimer Class Reference

Can be used to generate timings of multiple processes simultaneously and output logs.

This static class records timings of multiple processes simultaneously and allows for these timings to be written out in json format, one file for each process. Multiple overlapping sections can be timed independently on the same process. It also allows for the timings to be written out to json logfiles in a specified interval, for example every half hour.

Note that this class logs timings in milliseconds.
