Hi,
For mdrun, the option -nt means "Number of threads to start (0 is
guess)".
Is this option executed by openmp?
I used this option every time.
But today my technology stuff told me that we don't have openmp
installed in our computer.
It make me confused.
Why can I compile and run mdrun -nt 12 before?
mdrun does not use OpenMP at all. -nt creates standard threads, for
which the best performance will normally be one per physical core, which
will be auto-detected if you don't specify -nt.
