Hi,
I try to install Cuda using easybuild. it fails the sanity checks
:( Most likely I am missing an instruction.
I am trying with the easyconfig CUDA-7.5.18.eb in EB 2.8.2. Looking
through the logs it seems that it doesn’t install a driver. There is
a remark in the logs that this would need doing as root (reference to
sudo). Should I install pieces as root prior to running the EB cuda
easyconfig? If so, what should I do as root and what ill the
easyconfig do for me?
As far as I know, the CUDA easyconfig will only install the CUDA
runtime libraries.
But I don't have much experience with GPGPU systems, so maybe someone
else can correct me.
Since the driver is closely tied to the hardware you're using, and
needs admin privileges, EasyBuild indeed doesn't take care of that.
Yes - you want to have the NVIDIA driver installed first. If you have a
RHEL/CentOS/SUSE system, you should install the drivers from the
distro's repos. For example, on a CentOS 7 system I would do something like:
curl -L -o cuda-repo-rhel7-7.5-18.x86_64.rpm
http://developer.download.nvidia.com/compute/cuda/repos/rhel7/x86_64/cuda-repo-rhel7-7.5-18.x86_64.rpm
yum install cuda-repo-rhel7-7.5-18.x86_64.rpm
yum install nvidia-kmod
The way EasyBuild installs CUDA may not make much sense at first, but
this makes it easy to have multiple versions of CUDA installed
side-by-side without changing the drivers. This way, you can have the
latest driver along with CUDA 7.0, 7.5, 8.0, etc.
