Dear all,
I am running a 9000 atom system with GBSA (Gromacs 4.5.5) in a
Blue Gene/Q cluster. I got the speed 1.002 ns/day with 8 cores.
However, in my own workstation with 8 cores the same system can reach
nearly 10 ns/day (Intel(R) Xeon(R) CPU E5620 @ 2.40GHz). Can anyone
tell me what's wr

Hi all,
Just as the title, can Gromacs do Targeted MD simulations? If Yes, how
to set up the simulation procedure?

Gromacs to
read the energy from the file ener.edr, does the cutoff affect the values
of the energy? For example, when the cutoff is set to 1.2 nm and the PME method
is used, does the energy term "Coul-SR" read by g_energy contain the long range
part ?

Dear all,
I want to use umbrella sampling to calculate the PMF of the
conformational transition of a protein. What temperature coupling method and
pressure coupling method should I use? Berendsen temperature coupling or
Nose-Hoover temperature coupling? Or each one is OK?

Dear all,
What is the difference between the option Distance and Direction in
Umbrella Sampling?
In my opinion, the option Direction means that pulling the pull_group1
through the direction related to the reference group. Right? But how about
the option Distance?

Dear gmx-users,
Are there any comparisons of the code speed between Gromacs 3.0 and
Gromacs 4.0. In my calculation, I got a speed about 3.5ns/day of a system have
about 50,000 atoms, using 8 CPUs with Gromacs 3.3.1. In contrast, the speed can
reach up to 7.3ns/day when switch to Gromac
in third column sometimes smaller than
the number in second column?

I used g_nmeig to diagonalize the Hessian matrix, that I got the

the eigenvalues are "Eigenvalue [Gromacs units]". What is the '[Gromacs

1. pull_dim = Y Y Y
pull_vec1 = 1 0 0

2. pull_dim = Y N N
pull_vec1 = 1 0 0

3. pull_dim = Y N N
