Pre-requisites for installing Watson Studio Local with NVIDIA GPU support
Ensure that your servers meet the requirements for installing Watson Studio Local if you use a GPU NVIDIA operating system.
- Graphics Processing Unit system preparation
- Azure specific pre-install instructions
- General pre-install instructions
- More requirements for POWER8 with NVIDIA P100 GPUs
- More requirements for POWER9 with NVIDIA P100 GPUs
Graphics Processing Unit system preparation
Watson Studio Local supports GPUs by NVIDIA in Azure, AWS and Softlayer. If you have NVIDIA GPUs, you must perform the following steps before installing Watson Studio Local.
- Azure specific pre-install instructions
- If you are an Azure user, Azure is the only environment that has very specific kernel version
requirements. The default kernel level of a non HPC node will not be compatible with Watson Studio Local:
uname -r 3.10.0-514.28.1.el7.x86_64
To install a supported kernel level, run the following code:
yum install kernel-3.10.0-514.21.1.el7.x86_64 reboot
General pre-install instructions
Follow these steps, along with the example code, to pre-install packages, modules and update video drivers for Watson Studio Local pre-installation. For instructions on downloading NVIDIA drivers, jump to the section Download and install NVIDIA GPU driver.
- Install pciutils.
yum install pciutils
- Check for the default video
lsmod | grep -i nouveau
- Disable the default nouveau drivers using the following procedure below to a) update grub.conf
and b) blacklist.conf (depending on the image you use these might already be disabled. See step 2)
and c) reboot.
- Update grub to blacklist the nouveau driver by appending rd.driver.blacklist=nouveau
nouveau.modeset=0 to the GRUB_CMDLINE_LINUX line as shown
vi /boot/default/grub Change : GRUB_CMDLINE_LINUX="console=ttyS0,115200n8 console=tty0 net.ifnames=0 crashkernel=auto” to GRUB_CMDLINE_LINUX="console=ttyS0,115200n8 console=tty0 net.ifnames=0 crashkernel=auto rd.driver.blacklist=nouveau nouveau.modeset=0"
Complete the update by running the following command:
grub2-mkconfig -o /boot/grub2/grub.cfg
- Edit/create the file path /etc/modprobe.d/blacklist.conf and
- Reboot the system to activate the changes.
- Update grub to blacklist the nouveau driver by appending rd.driver.blacklist=nouveau nouveau.modeset=0 to the GRUB_CMDLINE_LINUX line as shown below.
- Add kernel-tools and kernel-devel packages by installing the version that matches the kernel
yum install kernel-devel-$(uname -r) kernel-headers-$(uname -r)
- Install gcc.
yum install gcc
- Acquire the dkms package from an external
rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm yum install dkms
Download and install NVIDIA GPU driver
Follow these steps, along with the examples provided, to download the latest NVIDIA driver:
- Download the NVIDIA 8.0 drivers: Download
- Install the NVIDIA
rpm -i nvidia-diag-driver-local-repo-rhel7-384.66-1.0-1.x86_64.rpm
- Install the drivers and then reboot. CUDA-enabled NVIDIA 8.0 GPU must be installed on the host
operating system compute nodes that have a
yum install cuda-drivers reboot
- Verify the installation:
nvidia-smiTip: If the command is slow, persistence mode might be enabled. Disable persistence with the following command:
nvidia-smi -pm 0
You are now ready to install Watson Studio Local and reap the accelerated compute speed of the GPU.
More requirements for POWER8 with NVIDIA P100 GPUs
If you have a POWER8 "Minsky" system with NVIDIA P100 GPUs, before you install Watson Studio Local on it, you must first install the NVIDIA GPU drivers the POWER8 system.
To install GPU drivers on Power8 hosts, install CUDA 9 from a local repo by following the Nvidia documentation.
- Clean up CUDA libraries from any prior
yum list installed | grep -i cuda yum remove cuda-* yum remove dkms.noarch yum remove epel-release yum remove nvidia-kmod*
- Get CUDA 9.2 libraries and install them on the
cd /tmp wget http://developer.download.nvidia.com/compute/cuda/repos/rhel7/ppc64le/cuda-repo-rhel7-9.2.88-1.ppc64le.rpm rpm -i cuda-repo-rhel7-9.2.88-1.ppc64le.rpm yum clean all yum install epel-release-latest-7.noarch.rpm yum install cuda #verify GPU can be seen nvidia-smi #verify if device file has been created ls /dev/nvidia-uvm #If device file not found download utility (https://www.ibm.com/support/knowledgecenter/en/SSBS6K_188.8.131.52/manage_cluster/verify_gpu.html) and execute it: ./cudaInit_ppc64le #verify file is created ls /dev/nvidia-uvm #verify if device log file exists: ls /var/lib/docker/volumes/ #if the device log file is missing, create the directory `nvidia_driver_xxx.xx` cd /var/lib/docker/volumes mkdir nvidia_driver_396.26
If the verification fails, you might need to restart your server.
