Hi Frank

do you mean completing a single recon faster? The easiest way to do that
is to use the -openmp <N> flag, and set <N> to the number of
threads/cores you want to use. Alternatively if you have enough RAM you
can just run multiple recon-alls at the same time (which will give you a
bigger effective speed increase)

cheers
