Hi Kevin,<br>
<br>
ParaView can use the GPU's and serial rendering performance is
better with the GPU. Parallel performance is a little harder to pin
down, since when multiple processes feed the same GPU this creates
resource contention which when the ratio of processes to GPU's is
high hurts performance. The performance you see all depends on the
specific GPUs and CPUs in question and the specifics of your use
case such as dataset size, poly's vs volume rendering, number of
procs per gpu and so on. <br>
<br>
You could very easily have two ParaView builds, one for hardware
rendering and one for software rendering available on the same
system and select the one to use as needed.<br>
<br>
To use PV in parallel you need to build it yourself, I'm assuming
you have done this. If you haven't taken precautions to build PV for
use with OSMesa then you are using what ever OpenGL library is
found, you can take a look in the CMake cache to see what was found
or you could use the ldd command on one of the compiled libraries,
point it at one of VTK's open gl rendering libs.<br>

<div>Hi,</div>
<div> </div>
<div>I try to use Paraview 3.14 in parallel. My server has 48
CPUs and good GPUs (I don’t know exactly which ones are on
the server).</div>
<div>Is it better to use Software or Hardware Rendering?</div>
<div>Well, I’m not sure if my Paraview takes usage of the GPUs
or only of the CPUs. The server admin thinks that Paraview
can’t really use the GPUs of the server, but how can I find
out if my Paraview uses Software or Hardware Rendering?</div>
<div> </div>
<div>Thanks,</div>
