[gmx-users] Is openmp necessary?

[Hsin-Lin Chiang]

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?

Sincerely yours,
Hsin-Lin
