Hi Andy,
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
for (int i = 0; i < *nscript; i++) {
pipeline->Initialize(pythonScriptNames[i]);
g_coprocessor->AddPipeline(pipeline);
}
When i run the simulation, i am getting following warning
Warning: In
/okyanus/users/uturuncoglu/progs/paraview-5.3.0/src/ParaViewCore/VTKExtensions/Core/vtkPVTrivialProducer.cxx,
line 66
vtkPVTrivialProducer (0x13816760): New time step is not after last time
step.
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.
Thanks,

Hi Ufuk,
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.
Cheers,
Andy

Thanks 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.
Thanks again,

Hi Ufuk,
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:
================
import script_a
import script_b
import script_c
def RequestDataDescription(datadescription):
script_a.RequestDataDescription(datadescription)
script_b.RequestDataDescription(datadescription)
script_c.RequestDataDescription(datadescription)
def DoCoProcessing(datadescription):
script_a.DoCoProcessing(datadescription)
script_b.DoCoProcessing(datadescription)
script_c.DoCoProcessing(datadescription)
===================
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.
Please let me know if this doesn't answer your question.
Cheers,
Andy

Hi All,
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.
