Dear colleagues,<br><br>I encountered the following error messages when trying out the checkpoint continuation functionality with MPI:<br><br><blockquote style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;" class="gmail_quote">
Reading file topol.tpr, VERSION 4.0.5 (single precision)<br><br>Reading checkpoint file state.cpt generated: Tue Oct 27 22:37:23 2009<br><br>8 - MPI_BCAST : Message truncated<br>[8] [] Aborting Program!<br>Abort signaled by rank 8: Aborting program !<br>
Exit code -3 signaled from [node address]<br>Killing remote processes...<br></blockquote><br>From a short google search I've come under the impression that this has to do with sending messages between the nodes that are larger than the receive buffer (note my total lack of practical experience with MPI programming). However, I have no idea where, if this is true, it might be happening.<br>
<br>My system has 44091 atoms, and the .cpt file size is 1.1M, which doesn't seems too large. Restarting works seemingly fine with serial mdrun.<br><br>Thank you in advance for any clues on this,<br>Vasilii<br>
