Multithreading on Minuit

Dear all, currently, I am working on a macro in which Minuit/Migrad is the default minimization engine for fitting and with big data matrices it is really slow. On both this forum, on many .ppt files across the internet and other documentation files I read that Minuit2 supports parallelization. Therefore, to speed up the fitting process, I tried this: //--introduces implicit multithreading ROOT::EnableImplicitMT(); //--set fitter to Minuit2 for multithreading ROOT::Math::MinimizerOptions…
