[Paraview] ParaView GUI hanging in debug mode

[Adriano Gagliardi]

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
