<p class="MsoNormal">Hi, <o:p></o:p></p>
<p class="MsoNormal">I am running mpich2 on couple windows server machines, which have some firewall restriction , namely only several ports are accessible on each machine.<o:p></o:p></p>
<p class="MsoNormal">So I explicitly have smpd listened on port 18000, which is enabled by the firewall, by “smpd.exe –p 18000”<o:p></o:p></p>
<p class="MsoNormal">However, when I call mpiexec on another machine by mpiexec.exe -hosts 1 10.115.130.153 1 -p 18000 hostname, the mpiexec stuck until timeout was thrown.
<o:p></o:p></p>
<p class="MsoNormal">From the log of smpd (listed below) , seems to me smpd issued the “reconnection request” and then spawns a new smpd manager process , which listens on port 56412, which unfortunately is not enabled by the firewall.<o:p></o:p></p>
<p class="MsoNormal">So my question is <o:p></o:p></p>
<p class="MsoNormal">Why I got this situation? And how can I limit the port to be used if this situation is unavoidable?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thank you very much<o:p></o:p></p>
