Hi, No, GROMACS long pre-dates useful implementations of MPI I/O (which anyway don't suit GROMACS needs), and handles its own MPI reduction and does I/O from a single rank per simulation. Mark On Fri, Mar 2, 2018 at 3:00 PM Amin Rouy wrote: > sorry Justin, I am familiar

Yes, you can besides the minor command-line interface differences, using MPI and thread-MPI works essentially the same way. http://www.gromacs.org/Documentation/Acceleration_and_parallelization#MPI.2c.c2.a0Thread-MPI -- Szilárd On Thu, Nov 28, 2013 at 11:07 AM, Richa Singh
