ACTIONS

- Redo the scaling plot several times to understand what error we have on the measured points, say 10 times, with a bit less events. Also we need to specify the type of the columns of the histograms. Also have more chunks of works to have a better balancing. Another point: measure the time needed for a single event.

Xavi

- TDF does not add a constant overhead wrt the original code, which is nice.

- Strong scaling: TDF and Rene's code - the scaling is identical

- Has an almost working numa aware TThreaded executor
