In addition to what Justin said, please notice that the reference by
Wittmann et al does not use SuMD. From what I read it uses standard MD
simulations. The other reference, where SuMD is actually presented, gives
all necessary information to produce your own version of it, since the
authors are unwilling to share their scripts (according to you).
What GROMACS tools need to be involved? That is for you to investigate.
Study their method and assess what program needs to be called at which
step. You'll also need to code a wrapper or a script to automate the
In sum, unfortunately there's no take away available, you need to prepare
and cook the meal yourself.
