[Paraview] ParaView GUI hanging in debug mode

[Adriano Gagliardi]

Thanks, Paul. I still can't stop it hanging, but I've resolved the bug I was
tracking anyway.
 
We have some totalview licences here, but I tend to prefer gdb. I remember
you saying you worked on DDT. Nothing like favouritism!

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.

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!

Paul

Dear All,

I'm trying to debug a parallel reader I am working on. I normally work with
gdb and ParaView in serial client-server mode, which works fine. However,
I'm now trying to debug the client-server mode when run in parallel using
MPICH2 and I'm encountering issues.

I've tried the following:

(1) Run parallel pvserver first -> attach gdb to a process id -> start
paraview client -> connect to server -> Result: client connected message
appears then the client hangs.

>>> mpirun -np 16 /path/to/ParaView-3.10.1-Debug/bin/pvserver
>>> gdb --pid xxxx
>>> paraview
>>> (connect to client)

(2) Run parallel pvserver first with gdb -> Result: pvserver does not start
properly (no port message or waiting for client).

>>> mpirun -np 16 gdb /path/to/ParaView-3.10.1-Debug/bin/pvserver
gdb>> run
>>> (server hangs)

I tried the second option just in case it worked, but I was sure (and
previous posts on the mailing lists showed) that the first option would
work. I am using ParaView 3.10.1 Release built on CentOS5.4 using standard
OS libraries with MPICH2.1.3.

Is there something I've done wrong here? Any suggestions?

Thanks,

Adriano
