Hi All,
i'm writing here because i would understand better the functionality of
pvbatch in Paraview.
At moment i'm able to run Paraview in batch launching a python script,
and it works good.
Here the line command i launch:
_//software/Paraview/ParaView-3.12.0-Linux-x86_64/lib/paraview-3.12/mpirun
-np 6 /software/Paraview/ParaView-3.12.0-Linux-x86_64/bin/pvbatch
python_script.py /_
The problem is that monitoring at processors loads and memory
consumption, it seems that it's actually working on one single
processor; in fact if i switch to /-np 2/ or even /-np1/ nothing changes
in terms of computing time.
This is happening with various Paraview versions (3.10 -3.12-4.1); is
there something missing in the line command? Some other options? Are
some Paraview filters just working as serial?
Another question would be about running pvbatch on clusters without
graphic cards: i know it's possible, compiling Paraview with OSMesa, and
adding in the command line the option
--/use-offscreen-rendering/. Could someone clarify also this point?
Thank you all in advance!
Daniele
