[gmx-users] Checkpoint files not being written

Do you have no cut-off's and nstlist set to 0?
That's the only case where I could see that checkpoints are missing.
If that's the case, please file a bugzilla so we don't forget to fix this for 4.5.2.
PS -cpnum has nothing to do with this.
I guess it's the bCPT = assignment in md.c that only gets set at NS steps or the last step.

> Hi All,
> I don't know if this is a new (intended) feature or a bug, so I figured I'd ask
> :) I'm running version 4.5.1 to do some implicit solvent simulations. What
> I've noticed is that, no matter how long the simulation runs, I only ever get a
> checkpoint file at the end of the simulation, and thus the checkpoint interval
> (which I have left at the default value of 15) is ignored. All the simulations
> I've done are sufficiently long (at least one hour) such that they should have
> produced checkpoint files according to this interval.
> Could this issue be related to the introduction of the -cpnum flag, which is set
> to "no" by default? I've poked around a bit in the mdrun code, but I easily
> lose my place trying to trace what's going on. I've tried specifically adding
> -cpnum to my mdrun command line, but still I am not receiving any intermediate
> checkpoint files at the requested -cpt interval.
