Hi,<br><br>That is very strange.<br>If you did not set the -cpt option, mdrun should only write a checkpoint file<br>every 15 minutes, not every 5 seconds.<br><br>What kind of machine are you running on?<br><br>Berk<br><br><br><hr id="stopSpelling">Date: Wed, 5 Nov 2008 06:58:33 -0500<br>From: xianghong001@gmail.com<br>To: gmx-users@gromacs.org<br>Subject: Re: [gmx-users] Re: writing checkpoint<br><br><div>Thanks, Berk:</div>

<div>My log file actually stop somewhere since its size didn't change for a long time. </div>
<div>Yes, looks like it keeps writing checkpoint info. </div>
<div>I should continue the simulation since the other file looks reasonable. </div>

<div>I didn't use option -cpt. </div>
<div>Thanks. <br></div>

<div>Hi,<br><br>Why do the log file seem to stop?<br>It keeps writing checkpoint info, right?<br>So I assume it is still running fine.<br><br>But it seems you have selected checkpointing at (nearly) every step.<br>Did you use -cpt 0?<br>
If you don't want checkpoints, you have to set -cpt -1.<br><br>Berk<br><br>
