    <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
              line  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>
