Dear All! Sorry for the delay in the reply, but I had a very long Christmas break and I just came back a few days ago. I managed to compile OpenSWR with Osmesa support using the autotools but it was not much faster than any of the OSMesa versions I tried, i.e. v10.5.5 and 11.0.7. I compiled the OpenSWR with libglx support and that might be the reason why the performance I experience is not so good as expected.
I have included hereafter the configure options I used on my CentOS 6.5 platform for reference: ./configure --prefix= --enable-gallium-osmesa --enable-dependency-tracking --enable-gallium-llvm=yes --enable-llvm-shared-libs --enable-swr-native --enable-sysfs --enable-texture-float --disable-dri --disable-egl --disable-glx --disable-gles1 --disable-gles2 --disable-opencl --disable-vdpau --disable-va --disable-xvmc --with-dri-drivers= --with-egl-platforms= --with-gallium-drivers=swr,swrast --with-gnu-ld --with-osmesa-bits=8 --with-swr-arch=CORE_AVX2 Hope this helps bringing a bit of clarity. Nonetheless, I was already very pleased with the improved rendering performance using the RC2 version. Now that PV 5.0.0 has been released, I will proceed to installation and repeat my benchmarks, the outcome of which I will be feeding back of course.

Here's a docker file we use to generate re-distributable libGL and libOSMesa binaries: https://github.com/chuckatkins/mesa-builds/blob/master/Dockerfile . In short though, you'll want to do the following: git clone https://github.com/OpenSWR/openswr-mesa.git mesa-swr cd mesa-swr scons build=release texture_float=yes swr_arch=core-avx2 libgl-xlib osmesa The libgl-xlib target will create a build/linux-x86_64/gallium/targets/libgl-xlib/libGL.so.1.5 output and the osmesa target will create a build/linux-x86_64/gallium/targets/osmesa/libosmesa.so output. You can also change swr_arch=core-avx2 to swr_arch=avx if you want to build for AVX instead of AVX2. - Chuck On Tue, Dec 22, 2015 at 10:14 AM, Utkarsh Ayachit <utkarsh.ayac...@kitware.com<mailto:utkarsh.ayac...@kitware.com>> wrote: > Also, thank you for liaising with the OpenSWR team in order to check if they > support or plan supporting OSMESA. Frank, I am told that OpenSWR on Github should work with OSMesa. I haven't tried it out myself, will give it a go once I get the a few other issues ironed out. Just wanted to let you know if you wanted to give it another go.
