CUDA Compatibility Drivers
This procedure is considered OmniSci experimental.
In some situations, you might not be able to upgrade NVIDIA CUDA drivers on a regular basis. To work around this issue, NVIDIA provides compatibility drivers that allow users to use newer features without requiring a full upgrade. For information about compatibility drivers, see https://docs.nvidia.com/deploy/cuda-compatibility/index.html.
Use the following commands to install the CUDA 11 compatibility drivers on Ubuntu:
wget
https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/cuda-ubuntu2004.pin
mv cuda-ubuntu2004.pin /etc/apt/preferences.d/cuda-repository-pin-600
apt-key adv --fetch-keys
https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/7fa2af80.pub
add-apt-repository "deb
https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/ /"
apt update
nvidia-smi
apt install cuda-compat-11-0
nvidia-smi
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-11.0/compat/
nvidia-smi
After the last
nvidia-smi, ensure that CUDA shows the correct version. The driver version will still show as the old version.
After installing the drivers, update the systemd files in /lib/systemd/system/omnisci_server.service.
In the service file, add the following environment path:
[Unit]
Description=OmniSci database server
After=network.target remote-fs.target
[Service]
Environment=LD_LIBRARY_PATH=/usr/local/cuda-11.0/compat/
User=sam
Group=sam
WorkingDirectory=/opt/omnisci
ExecStart=/opt/omnisci/bin/omnisci_server --config /var/lib/omnisci/omnisci.conf
KillMode=control-group
SuccessExitStatus=143
LimitNOFILE=65536
Restart=always
[Install]
WantedBy=multi-user.target
If that path does not exist, make ensure you have installed the compatibility drivers correctly.
