Hi ncos,
First things first: we broke KNC builds when we moved to Embree 2.7.1, C++11, and the new TBB tasking system backend. This is exactly the issue I am currently working on where I currently have everything building but having issues running right now. I hope to have those fixed within the next few days...I'll post here when I have merged my working branch into our 'release-0.9' branch.
The second thing is that KNC builds are only supported with the Intel compiler because GCC and CLANG do not emit code for KNC (it has a different instruction set to x86). People have prepped GCC (and CLANG?) for the next generation Xeon Phi, Knights Landing. As a part of my fixes for KNC, I will appropriately hide KNC build options in CMake to reduce confusion and prevent builds which won't compile.
Again, I'll post here and close the issue when the fixes have been merged to 'release-0.9'.
Thanks for the feedback,
Jeff

Quick update: the KNC code paths (both COI and MPI) now compile and run again in 'release-0.9'. However, there's still a bug lingering in volumes which crashes on mic, but ospModelViewer and ospStreamlineViewer both work for triangle meshes and non-polygonal data.
While those fixes are merged, the github issue will remain open until volume rendering is fixed. Keep in mind that KNC is less of a priority for us right now, so it may be a while before remaining KNC issues are fixed.
Cheers,
