Hi,<br><br>Do you have no cut-off's and nstlist set to 0?<br>That's the only case where I could see that checkpoints are missing.<br>If that's the case, please file a bugzilla so we don't forget to fix this for 4.5.2.<br><br>PS -cpnum has nothing to do with this.<br>I guess it's the bCPT = assignment in md.c that only gets set at NS steps or the last step.<br><br>Berk<br><br>> Date: Fri, 10 Sep 2010 11:08:26 -0400<br>> From: jalemkul@vt.edu<br>> To: gmx-users@gromacs.org<br>> Subject: [gmx-users] Checkpoint files not being written<br>> <br>> <br>> Hi All,<br>> <br>> I don't know if this is a new (intended) feature or a bug, so I figured I'd ask <br>> :) I'm running version 4.5.1 to do some implicit solvent simulations. What <br>> I've noticed is that, no matter how long the simulation runs, I only ever get a <br>> checkpoint file at the end of the simulation, and thus the checkpoint interval <br>> (which I have left at the default value of 15) is ignored. All the simulations <br>> I've done are sufficiently long (at least one hour) such that they should have <br>> produced checkpoint files according to this interval.<br>> <br>> Could this issue be related to the introduction of the -cpnum flag, which is set <br>> to "no" by default? I've poked around a bit in the mdrun code, but I easily <br>> lose my place trying to trace what's going on. I've tried specifically adding <br>> -cpnum to my mdrun command line, but still I am not receiving any intermediate <br>> checkpoint files at the requested -cpt interval.<br>> <br>> -Justin<br>> <br>> -- <br>> ========================================<br>> <br>> Justin A.
