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

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

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.

  1. Install pciutils.
    yum install pciutils
  2. Check for the default video driver.
    lsmod | grep -i nouveau
  3. 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.
    1. 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.
      vi /boot/default/grub
       Change : GRUB_CMDLINE_LINUX="console=ttyS0,115200n8 console=tty0
      net.ifnames=0 crashkernel=auto”
       GRUB_CMDLINE_LINUX="console=ttyS0,115200n8 console=tty0
      net.ifnames=0 crashkernel=auto rd.driver.blacklist=nouveau

      Complete the update by running the following command:

      grub2-mkconfig -o /boot/grub2/grub.cfg
    2. Edit/create the file path /etc/modprobe.d/blacklist.conf and append.
      blacklist nouveau
    3. Reboot the system to activate the changes.
  4. Add kernel-tools and kernel-devel packages by installing the version that matches the kernel version.
    yum install kernel-devel-$(uname -r)
    kernel-headers-$(uname -r)
  5. Install gcc.
    yum install gcc
  6. Acquire the dkms package from an external repo.
    rpm -ivh
    yum install dkms

Download and install NVIDIA GPU driver

Follow these steps, along with the examples provided, to download the latest NVIDIA driver:

  1. Download the NVIDIA 8.0 drivers: Download Drivers
    Figure 1. Example of selected driver

    Type: Tesla Series: K-Series Product: Tesla K80 System: Linux 64-bit RHEL CUDA Toolkit: 8.0 Language: US (English)

  2. Install the NVIDIA repo.
    rpm -i nvidia-diag-driver-local-repo-rhel7-384.66-1.0-1.x86_64.rpm
  3. 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 GPU.
    yum install cuda-drivers
  4. Verify the installation:
    Tip: 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.

  1. Clean up CUDA libraries from any prior installations:
    yum list installed | grep -i cuda
    yum remove cuda-*
    yum remove dkms.noarch
    yum remove epel-release
    yum remove nvidia-kmod*
  2. Get CUDA 9.2 libraries and install them on the system:
    cd /tmp
    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
    #verify if device file has been created
    ls /dev/nvidia-uvm
    #If device file not found download utility ( and execute it:
    #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.
