<div>Hi:</div>
<div> </div>
<div>Unplug the wire of node1 : mpiexec abort</div>
<div> </div>
<div>Unplug the wire of node2: the MPI task at node2 finally disappeared, the MPI task at node1 hangs (from the console window it just hangs)</div>
<div> </div>
<div>regards,</div>

<div>Hi all:</div>
<div> </div>
<div>I have run 2 MPI tasks in 2 different nodes. (2 nodes are with Windows XP Professional)</div>
<div> </div>
<div>The mpiexec command is run on node1.</div>
<div> </div>
<div>During the parallel computing, if I unplug the network wire of node1, the parallel computing will crash.</div>
<div> </div>
<div>But if I unplug the network wire of node2, the parallel computing just hangs! I notice that the hanging results from</div>
<div>that I unplug the wire before a MPI_Barrier, therefore node1 waits at MPI_Barrier, but node2 will never reach that point.</div>
<div> </div>
<div>Is there any mechanism to make the parallel computing crash after the network wire of node2 is unplugged ?</div>
<div> </div>
<div>regards,</div>
<div> </div>
