<div dir="ltr">Hi,
<div><br>
</div>
<div>I am trying to compile and use mpich-1.2.7p1 with threaded listener (i.e. configured with --enable-threaded-listener). However, I cannot even run a simple mpi example with the resulting mpich.</div>
<div><br>
</div>
<div>I need to use threaded listener because the environment I am compiling for (kind of embedded environment) does not have fork (no heavy processes).</div>
<div><br>
</div>
<div>The error I get with the mpich with threaded listener is:</div>
<div><br>
</div>
<div>rm_2889: 1103279872: p4_error: listener select: -1</div>
<div> p4_error: latest msg from perror: Bad file descriptor</div>
<div>p0_2710: (2.097656) net_recv failed for fd = 5</div>
<div>p0_2710: 3778266880: p4_error: net_recv read, errno = : 104</div>
<div><br>
</div>
<div>Has anyone experienced a similar problem?</div>
<div><br>
</div>
<div>Thanks in advance,</div>
<div>Eduardo</div>
