I though you could also get binaries (nvcc) and the rest by compiling CUDA, i.e. https://developer.nvidia.com/compute/cuda/8.0/Prod2/local_installers/cuda_8.0.61_375.26_linux-run <https://developer.nvidia.com/compute/cuda/8.0/Prod2/local_installers/cuda_8.0.61_375.26_linux-run> but of course one can also set it as an externally provided package. > trouble when you upgrade your kernel or your drivers (I have been there...). > > I guess one way is to use directly cuda compiler wrappers.

I'll you know if I hit a road block. great! If you hit some issues using/building with CUDA, maybe create an issue/question on either https://github.com/LLNL/spack/issues <https://github.com/LLNL/spack/issues> or https://groups.google.com/forum/?fromgroups#!forum/spack <https://groups.google.com/forum/?fromgroups#!forum/spack> I am sure one of the sysadmins who use Spack to manager HPC cluster must be playing with CUDA as well.
