Hi All,<br>
<br>
i'm writing here because i would understand better the functionality
of pvbatch in Paraview.<br>
<br>
At moment i'm able to run Paraview in batch launching a python
script, and it works good.<br>
<br>
Here the line command i launch:<br>
<u><i>/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 </i></u><br>
<br>
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 <i>-np 2</i> or even <i>-np1</i>
nothing changes in terms of computing time.<br>
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?<br>
<br>
<br>
<br>
<br>
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 <br>
--<i>use-offscreen-rendering</i>. Could someone clarify also this
point?<br>
<br>
Thank you all in advance!<br>
