[Paraview-developers] OSPRay render

[ƦOB COASTN]

Greetings!

This is first message to the developers list
The recent integration of OSPRay as a module sparks interest.

I am trying to run ParaView with OSPRay as VTK module.
I want to utilize Xeon Phi KNC.

The compilation from source needs host binaries for x86_64
architecture, and mic binaries for k1om.

ParaView master branch was linked with OSPRay release v0.10.1.
This source was linked with the pre-compiled embree-2.9.0 release
libraries for each k1om and x86_64. *build log linked

(~50mb)

ParaView correctly renders with both legacy OpenGL and OSPRay without
issue when using the host x86_64 build. *screenshots linked

The issue occurs after MPI launch of PVserver.
The MPI execution produces errors exactly when the OSPRay rendering is
enabled. *screenshot linked

I concurrently see these messages in another terminal:


[coast at coast77 ~]$ /home/ParaView/build-host/bin/paraview

ERROR: In /home/ParaView/VTK/Common/System/vtkSocket.cxx, line 572

Any recommendations?

Thanks,
