04:02 PM GROMACS Bug #2867: abnormal box fluctuations on GPUs still there
PS Thanks Alexander for all the detailed information!
04:01 PM GROMACS Bug #2867: abnormal box fluctuations on GPUs still there
What I only noticed or realized now is that there is a switch from from 3 center of mass motion removal groups in the...
01:59 PM GROMACS Bug #2867: abnormal box fluctuations on GPUs still there
Has someone observed if there first is a conformational rearrangement and then the box starts fluctuating or first th...
12:17 PM GROMACS Bug #2867: abnormal box fluctuations on GPUs still there
I would like to get the input for the CHARMM gui mdp parameter runs that failed, so I can check those myself.
12:16 PM GROMACS Bug #2867: abnormal box fluctuations on GPUs still there
I was also thinking of the stability of the CHARMM forcefield itself (not the implementation in GROMACS).
In Stock...
11:40 AM GROMACS Bug #2867: abnormal box fluctuations on GPUs still there
So you have seen no problems at all with the charmm-gui parameters on both CPU and GPU?
Have others used the same pa...
10:31 AM GROMACS Revision 1e3bd57a: Fix perturbed bonded bug
Recent commit 0c26c550 allowed perturbed bonded interactions to use
SIMD kernels that only used the A-state parameter...
09:05 AM GROMACS Bug #2867: abnormal box fluctuations on GPUs still there
I now tried Berendsen pressure coupling with tau-p both 5 and 10 ps. The box dimensions now behave much smoother and ...

02:23 PM GROMACS Task #3064 (New): add test for perturbed bonded forces
We do not catch bugs where a (forces-only) bonded kernel compute forces with the A-state parameters instead of the co...

10:16 PM GROMACS Bug #2867: abnormal box fluctuations on GPUs still there
Consensus is growing in the community that second order coupling like Nose-Hoover and Parrinello-Rahman causes issues...
