<div class="moz-cite-prefix">Hi Andy,<br>
<br>
I tested you suggestion about using multiple script in
co-processing. In this case, i used following code in the adaptor
side to add multiple pipeline<br>
<br>
for (int i = 0; i < *nscript; i++) {<br>
pipeline->Initialize(pythonScriptNames[i]);<br>
g_coprocessor->AddPipeline(pipeline);<br>
}<br>
<br>
When i run the simulation, i am getting following warning<br>
<br>
Warning: In
/okyanus/users/uturuncoglu/progs/paraview-5.3.0/src/ParaViewCore/VTKExtensions/Core/vtkPVTrivialProducer.cxx,
line 66<br>
vtkPVTrivialProducer (0x13816760): New time step is not after last
time step.<br>
<br>
the output seems not correct and it is zoom out version of second
pipeline (png file). The first pipeline is not even triggered. Do
i missing something in here? BTW, i am using PV 5.3.<br>
<br>
Thanks,<br>

If you create a vtkCPythonScriptPipeline, when you
initialize it with the script file name (which has to be
done on each process) everything will be taken care of with
respect to broadcasting the file contents from process 0 to
the others. We aren't sophisticated enough to parse the
Python script to see if it imports other scripts that are
not part of ParaView (e.g. paraview.simple) or Python (e.g.
sys). That is why I recommended the first approach as
opposed to the second approach above. Depending on the
compute platform and how many MPI processes are in the run
the difference may be negligible but having 100K processes
or more trying to access the same file can seriously slow
down an HPC machine.<br>

Andy. That is exactly what i am looking for. The
broadcasting mechanism is not clear to me yet. Do i need
to broadcast only the file names? Anyway, i will try to
implement it and see what is going on there.<br>

Thanks again,<br>

Unless I'm not understanding
your question correctly, I think
you can get what you want by
adding in multiple
vtkCPPythonScriptPipelines to
your vtkCPProcessor object in
your adaptor. Alternatively if
you want to have a single,
master Catalyst script handling
other Catalyst scripts you can
do something like the following:<br>
================<br>
</div>
import script_a<br>
</div>
import script_b<br>
</div>
import script_c<br>
<br>
</div>
def RequestDataDescription(<wbr>datadescription):<br>
</div>
script_a.<wbr>RequestDataDescription(<wbr>datadescription)<br>
script_b.<wbr>RequestDataDescription(<wbr>datadescription)<br>
script_c.<wbr>RequestDataDescription(<wbr>datadescription)<br>
<br>
def DoCoProcessing(<wbr>datadescription):<br>
</div>
script_a.DoCoProcessing(<wbr>datadescription)<br>
script_b.DoCoProcessing(<wbr>datadescription)<br>
script_c.DoCoProcessing(<wbr>datadescription)<br>
===================<br>
<br>
</div>
The first way is the recommended way though as
that should be more efficient by having
process 0 read the scripts and broadcasting
the script contents to the other processes
for use. The second method will only do that
for the master script.<br>
<br>

<div>Please let me know if this doesn't answer
your question.<br>

I just wonder that is it possible to trigger
multiple visualization pipeline in the same
time with co-processing. The co-processing
script generator plugin mainly outputs only
single pipeline at a time and that is fine but
what about combining multiple Python script
(generated by plugin) using higher level
Python script to trigger multiple pipelines.
So, i think that this will be much efficient
way to look at different part of the data
without writing to the disk. I am not sure but
somebody else might do it before.<br>
