How do I update NVIDIA drivers for V100 GPUs in the cloud?

To update NVIDIA drivers for V100 GPUs in Cyfuture Cloud, first ensure your VM or instance is powered on with access to the GPU. Update your operating system packages, then download the appropriate NVIDIA driver compatible with the V100 GPU and your OS from the official NVIDIA site or repository. Follow NVIDIA's installation instructions carefully, including disabling nouveau drivers if necessary. After installation, reboot the instance and verify the driver installation to ensure the GPU driver is updated correctly for optimal performance.

Understanding NVIDIA V100 GPU Drivers

NVIDIA Tesla V100 GPUs require specific drivers that support the Volta architecture. These drivers are crucial for enabling CUDA capabilities necessary for AI, deep learning, and high-performance computing workloads in the cloud. Proper driver updates ensure compatibility with the latest CUDA toolkit versions and improved system stability on your Cyfuture Cloud GPUs.​

Preparing Your Cyfuture Cloud Instance

Log in to your Cyfuture Cloud dashboard and access your GPU instance with V100 GPUs.

Choose an operating system supported by NVIDIA drivers (commonly Ubuntu, CentOS, or similar Linux distros).

Update your OS to ensure existing packages are up to date. On CentOS, for example, this means running commands like sudo dnf update; on Ubuntu, use sudo apt-get update && sudo apt-get upgrade.​

Disable conflicting drivers such as nouveau, which can interfere with the NVIDIA driver installation.​

Step-by-Step NVIDIA Driver Update

Check Current Driver: Before updating, verify your current GPU driver version by running nvidia-smi.

Download NVIDIA Driver:

Visit the official NVIDIA Driver Download page for "Tesla V100" GPUs.

Select your OS and download the latest compatible driver.

Prepare the System:

Disable nouveau driver if active through modprobe blacklist or kernel options.

Install kernel headers and development packages needed for building NVIDIA modules.

Install the Driver:

Follow NVIDIA’s installation steps using the downloaded runfile or through package managers if available.

For example, on Ubuntu:

text

sudo apt-get install -y build-essential linux-headers-$(uname -r)

sudo bash NVIDIA-Linux-x86_64-.run

Or use CUDA Toolkit installation that bundles compatible drivers.

Reboot:

After installation, reboot the instance to load the new drivers.

Verify Installation:

Run nvidia-smi again to confirm the new driver version is active.​

Verifying Installation

Post-installation, verification is key to confirm the driver update was successful:

Use command nvidia-smi to check driver version and GPU status.

Run CUDA samples or test frameworks like TensorFlow or PyTorch for functional testing.

Ensure no errors during system boot related to GPUs.​

Common Issues and Troubleshooting

Kernel Upgrade Caution: Avoid upgrading the Linux kernel without recompiling or reinstalling NVIDIA drivers as this can break CUDA functionality.

Nouveau Driver Conflict: Nouveau must be disabled before installing NVIDIA drivers to prevent conflicts.

Version Compatibility: Ensure NVIDIA driver version matches the CUDA toolkit version and OS compatibility.

Persistence Mode: Enabling NVIDIA Persistence Mode helps maintain GPU performance post reboot on cloud instances.​
