[gmx-users] Failed to lock: pre.log (Gromacs 4.5.3)

[Baofu Qiao]

Hi all,

I got the error message when I am extending the simulation using the
following command:
mpiexec -np 64 mdrun -deffnm pre -npme 32 -maxh 2 -table table -cpi
pre.cpt -append

The previous simuluation is succeeded. I wonder why pre.log is locked,
and the strange warning of "*Function not implemented*"?

Any suggestion is appreciated!
