<p class="MsoNormal" style="margin-bottom:12.0pt">Hi Lukasz,<o:p></o:p></p>
</div>
<p class="MsoNormal">Here's a not too hacky workaround for doing your parallel use case 1. I think the main issue is that the seed source needs to be fully available on all processes. By using disk_out_ref.ex2 in parallel or the D3 filter and then the slice
it is making this not true. What you can do is the following (all in parallel if you want):<o:p></o:p></p>
<ol start="1" type="1">
<li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level1 lfo1">
Read in disk_out_ref.ex2<o:p></o:p></li><li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level1 lfo1">
Create slice <o:p></o:p></li><li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level1 lfo1">
Save slice output in vtm format<o:p></o:p></li><li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level1 lfo1">
Read slice output back in<o:p></o:p></li><li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level1 lfo1">
Create D3 from disk_out_ref<o:p></o:p></li><li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level1 lfo1">
Do STCS with D3 and reader as the seeds<o:p></o:p></li></ol>
<p>I think for readers that work can automatically partition the data in parallel you may be able to skip steps 2 and 3 though and use the slice output as the seeds. If you try this and it doesn't work please let us know. Also, I didn't verify my fix for your
parallel 2, 3 and 4 use cases but if you try similar stuff for that and it doesn't work, please us know that as well.<o:p></o:p></p>
<p>Best,<o:p></o:p></p>

I made a little test with the disk_out_ref.ex2 in serial and parallel by and this is what I found. I am using Paraview v5.0.0 compiled from source with system libs linked against openmpi 1.7.1. I also briefly checked with other mpi flavours and under Windows
with the MPI enabled binaries from <a href="http://paraview.org" target="_blank">

http://www.paraview.org/Bug/view.php?id=15342</a> and an old post <a href="https://cmake.org/pipermail/paraview/2009-December/014909.html" target="_blank">
https://cmake.org/pipermail/paraview/2009-December/014909.html</a> but no solutions to this problem. Interestingly the common Stream Tracer filter works in parallel with both point and high resolution line sources.
