Hi,
I'm running PV on an 8-node cluster in desktop-delivery mode. Each node
has an NVidia Geforce GTX460, NVidia driver 260.19.26, supporting OpenGL
4.1.0. OS is Debian 6.0 x86_64. In case it matters I pass
--use-offscreen-rendering to pvserver.
With both 3.10.1 and 3.12.0 GPU-based volume rendering is failing. I get
purple rectangular regions in the client, presumably the pieces of
viewport each node was supposed to render. I get lots of errors from the
pvserver processes:
after uniforms for textures ERROR (x501) Invalid value
framebuffer has an attachment error
framebuffer has an attachment error
SetupRender ERROR (x506) invalid framebuffer operation ext
framebuffer has an attachment error

[...]

render clipped 1 ERROR (x506) invalid framebuffer operation ext
render clipped 1 ERROR (x506) invalid framebuffer operation ext
render clipped 1 ERROR (x506) invalid framebuffer operation ext
[...]
Is this a problem with my local setup? If so, are there tests I can do
to figure out what's wrong?
More info: clients are binaries from paraview.org. The servers are
compiled by myself, mostly to enable MPI. E.g. for the 3.12.0 binaries I
use:
cmake \
-DCMAKE_C_COMPILER=/software/openmpi/gnu/1.4.3/bin/mpicc \
-DCMAKE_CXX_COMPILER=/software/openmpi/gnu/1.4.3/bin/mpicxx \
-DCMAKE_INSTALL_PREFIX=/software/paraview/3.12.0 \
-DCMAKE_BUILD_TYPE=Release \
-DPARAVIEW_BUILD_QT_GUI=ON \
-DPARAVIEW_USE_MPI=ON \
-DPARAVIEW_ENABLE_PYTHON=ON \
-DVTK_USE_MPI:BOOL=ON \
-DVTK_MPIRUN_EXE:FILEPATH=/software/openmpi/gnu/1.4.3/bin/mpirun \
-DPARAVIEW_INSTALL_DEVELOPMENT=ON \
../ParaView-3.12.0
Best regards,
Paul
