I searched through the archive of this mailing list and there is only one thread that has this OFI poll failed error. </div>
<div>In the thread, it mentioned this has something to do with the device configuration of ch4:ofi ?</div>
<div>I checked my configure log and it has </div>
<div>device : ch4:ofi (embedded libfabric) </div>
<div>in the configuration when I built the MPI. So I am wondering if I should switch this option to something else? If this will fix it. I am not too sure what other option I could substitute for ch4:ofi.</div>
<div><br>
</div>
<div>*****************************************************</div>
<div><br>
</div>
<div>Next I tried running configure for a build with the --enable-device = ch3:nemesis option. </div>
<div>Now again I can run the cpi on any of host1 or host2 alone. If I run it on host1 and host2 together, it just crashed with a core dump.</div>
<div><br>
</div>
<div>Using the --enable-device = ch3:sock configure option resulted in more or less the same problem but now it just quits silently when running on host1 and host2 together.</div>
<div><br>
</div>
<div>Any ideas?</div>
<div>Thanks!</div>
