Is there any way to limit the number of threads RooFit uses when performing FFT’s?
On my cluster I’ve got some users using those routines and their jobs rapidly spawn a large number of threads, significantly more than the number of cores on a node. Is there any call they can make in their code to cap the number of threads to the number of cores or need I recompile root/fftw? (If so, which extra flags should I use?)
Thanks in advance,
