<p>Dear Paraview team,</p>
<p>we are currently studying the opportunity of migrating our
computing grid environment from "module" system to "nix" packaging
system (<a class="moz-txt-link-freetext" href="https://nixos.org/">https://nixos.org/</a>). In that purpose, I'm trying to
compile and pack Paraview 5.2.0 with its dependencies with nix
packages (<a class="moz-txt-link-freetext" href="https://nixos.org/nixos/packages.html">https://nixos.org/nixos/packages.html</a>). <br>
</p>
<p>To do so, I first installed nixos on a local laptop and give it a
try. The main issue I encountered was to update my nixos kernel
with native videocard drivers but OK, that's done. Then using the
attached nix package script (a slight evolution on paraview 4.0.1
existing one), I could have packetized 5.2.0 succesfully and it
runs very well.</p>
<p>However, I still get an error when I'm trying to use MPI
functionality. The MPI itself with parallelism works, as I can run
a auto-MPI session without problem. The issue occurs when <b>servermanager.Disconnect()
function is called => Seg fault</b> with no more info... The
bad thing is that the Disconnect function is called every time I
would like to connect to a server (to disconnect the built-in
one). This is also the case when passing the pvserver in
command-line argument.</p>
<p>Do you have an idea of the cause of this seg fault ? Maybe could
you help me find any useful test to debug this ?</p>
<p>Thanks in advance for your support,</p>
<p>Best regards,</p>
<p>Yves<br>
