<p>When debugging in parallel you will need to start the job without gdb and
then connect individually to each of the pvserver processes with gdb.</p>
<p>The other option is to use a parallel debugger such as DDT or totalview -
both are commercial but you can get a trial license. Note: I'm biased towards
DDT as I used to work for Allinea and was one of the original developers!</p>

All,<br><br>I'm trying to debug a parallel reader I am working on. I normally
work with<br>gdb and ParaView in serial client-server mode, which works fine.
However,<br>I'm now trying to debug the client-server mode when run in
parallel using<br>MPICH2 and I'm encountering issues.<br><br>I've tried the
following:<br><br>(1) Run parallel pvserver first -> attach gdb to a
process id -> start<br>paraview client -> connect to server ->
Result: client connected message<br>appears then the client
hangs.<br><br>>>> mpirun -np 16
/path/to/ParaView-3.10.1-Debug/bin/pvserver<br>>>> gdb --pid
xxxx<br>>>> paraview<br>>>> (connect to client)<br><br>(2)
Run parallel pvserver first with gdb -> Result: pvserver does not
start<br>properly (no port message or waiting for client).<br><br>>>>
mpirun -np 16 gdb /path/to/ParaView-3.10.1-Debug/bin/pvserver<br>gdb>>
run<br>>>> (server hangs)<br><br>I tried the second option just in
case it worked, but I was sure (and<br>previous posts on the mailing lists
showed) that the first option would<br>work. I am using ParaView 3.10.1
Release built on CentOS5.4 using standard<br>OS libraries with
MPICH2.1.3.<br><br>Is there something I've done wrong here? Any
suggestions?<br><br>Thanks,<br><br>Adriano<br><br>===================================<br><br>Adriano
