CUDA repository setup

NVIDIA hosts package repositories at:

https://developer.download.nvidia.com/compute/cuda/repos/<distro>/<arch>/

Where <distro> is one of rhel6, rhel7, rhel8, rhel9, rhel10, sles11, sles12, sles15, ubuntu1404, ubuntu1604, ubuntu1804, ubuntu2004, ubuntu2204, ubuntu2404, ubuntu2604 and <arch> is x86_64, ppc64le (RHEL 7-8, Ubuntu 14.04-16.04), or sbsa (ARM).

Note

Older Ubuntu releases (14.04, 16.04) use ppc64el instead of ppc64le in the repository URL path.

Online setup

If nodes have network access, point otherpkgdir at the NVIDIA URL directly:

chdef -t osimage <osimage> -p \
  otherpkgdir=https://developer.download.nvidia.com/compute/cuda/repos/<distro>/<arch>

The otherpkgs postscript will configure this as a package repository on the node during provisioning.

Offline setup (air-gapped clusters)

For clusters without internet access, mirror the NVIDIA repository to a local directory under /install on the management node.

RHEL

Use dnf download (or yumdownloader on RHEL 7) on a system with internet access to download the CUDA packages and their dependencies:

mkdir -p /install/cuda/<distro>/<arch>
dnf download --resolve --destdir /install/cuda/<distro>/<arch> cuda
createrepo /install/cuda/<distro>/<arch>

For EPEL dependencies such as dkms:

dnf download --resolve --destdir /install/cuda/<distro>/<arch> dkms
createrepo /install/cuda/<distro>/<arch>

SLES

Use zypper download on a system with internet access:

mkdir -p /install/cuda/<distro>/<arch>
zypper --pkg-cache-dir /install/cuda/<distro>/<arch> download cuda
createrepo /install/cuda/<distro>/<arch>

For a runtime-only installation, replace cuda with cuda-runtime-<major>-<minor> (e.g., cuda-runtime-13-2).

Ubuntu

Use apt download on a system with internet access:

mkdir -p /install/cuda/<distro>/<arch>
cd /install/cuda/<distro>/<arch>
apt download cuda $(apt-cache depends --recurse --no-recommends \
    --no-suggests --no-conflicts --no-breaks --no-replaces \
    --no-enhances cuda | grep "^\w" | sort -u)
dpkg-scanpackages . /dev/null | gzip -9c > Packages.gz

Note

The offline approach requires downloading packages on a system running the same OS version and architecture as the target nodes. Transfer the resulting directory to the management node under /install.
