[gmx-users] time of simulation

[mahmoud]

Hello Dear GMX Users,
 
 
I have installed Gromacs 4 on a QUAD computer by Fedora 11.
 
When I do not use the "mpirun -np 4 g_mdrun ... " command, just one CPU is used.
When I use the "mpirun -np 4 g_mdrun ... " command, all of the 4 CPUs are used.
 
But the problem is that the time of simulation, although 4 CPUs are used, does not change by using the mpirun command!

Can you help me please how I can fasten the time of simulation!
 
 
Thank you very much for your kind help.
 
Best,
Mahmoud<
