<div>Hi Sebastien,<br>
<br>
thanks for the reply!<br>
<br>
The script is about creating slice and sweep animation. But it's
working fine, i think there is no problem in it. <br>
Do you need the script to understand something about the
parallelization?<br>
<br>
Let me know!<span class="HOEnZb"><font color="#888888"><br>

<div bgcolor="#FFFFFF" text="#000000"> 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
lineĀ the option <br>
--<i>use-offscreen-rendering</i>. Could someone clarify
also this point?<br>
<br>
Thank you all in advance!<span><font color="#888888"><br>
