Is there any option to make a ROOT minimizer to run with multithread? I am not asking about thread safety but about just speed improvement of the minimizer by making its internal calculation run in multithread.
Hi,
The speedup will come by implementing the function to minimise in multithreads, and this can be done.
The minimiser itself does small calculations and normally does not need to be run in multi-thread mode.
In ROOT for example in fitting we can compute the likelihood function or chi-square using multi-threads
