How to Upgrade or Migrate from V100 to H100 GPU Instances?

Upgrading or migrating from V100 to H100 GPU instances on Cyfuture Cloud involves evaluating your workload requirements, provisioning new H100 GPU instances, installing compatible drivers and CUDA toolkits, migrating your applications and data, and optimizing your environment to leverage the advanced capabilities of the H100 GPUs. Cyfuture Cloud supports flexible GPU instance scaling and migration, ensuring a smooth transition with performance benefits for AI, ML, and HPC workloads.

Understanding V100 and H100 GPU Differences

The NVIDIA Tesla V100 is based on the Volta architecture and delivers robust AI and HPC processing power. In contrast, the H100 GPU, built on the Hopper architecture, offers substantial performance improvements including better AI training speed, inference capabilities, FP8 precision support, and a Transformer Engine optimized for large language models (LLMs). Moving to H100 instances allows you to accelerate AI workloads significantly and scale efficiently with Cyfuture Cloud’s infrastructure designed to support these GPUs with advanced cooling and networking.​

Preparations Before Migration

Before upgrading, assess your workload demands thoroughly. Determine whether your applications can benefit from H100’s features like mixed precision and FP8 optimizations. Make sure your current AI frameworks (TensorFlow, PyTorch, CUDA) and OS are compatible with H100 GPU drivers. Backup critical data and configurations on your V100 instances to avoid data loss during migration.​

Step-by-Step Migration Process on Cyfuture Cloud

1. Provision H100 GPU Instances
Log in to your Cyfuture Cloud dashboard, navigate to the compute section, and deploy new virtual machines with H100 GPU instances. Choose an AI-optimized OS (e.g., Ubuntu 20.04) and configure appropriate storage and network settings.

2. Install NVIDIA H100 Drivers and CUDA Toolkit
Download and install the latest NVIDIA drivers and CUDA toolkit compatible with the H100 from the official NVIDIA site. Cyfuture Cloud provides support and documentation for driver installation to ensure optimal performance.

3. Migrate Applications and Data
Transfer your AI models, datasets, and application data from V100 instances to the new H100 environment. Use secure and fast data transfer methods like SCP or cloud storage tools.

4. Update and Optimize AI Frameworks
Install or update AI frameworks like TensorFlow and PyTorch, ensuring they are optimized for H100’s architecture. Enable mixed precision and FP8 features where applicable.

5. Test and Validate Performance
Run benchmarks and test your applications on H100 to confirm performance gains and stability. Use tools like nvidia-smi to monitor GPU utilization and driver status.

6. Decommission V100 Instances
Once satisfied with the H100 environment, you may scale down or terminate V100 instances to optimize costs.

Cyfuture Cloud facilitates this migration with 24/7 technical support, onboarding assistance, and detailed guides tailored to GPU upgrades.​

Driver and Software Compatibility

Updating NVIDIA drivers is critical when switching GPUs. The V100 uses drivers optimized for the Volta architecture, whereas H100 requires the latest drivers supporting Hopper features. It’s recommended to uninstall old drivers and then freshly install the new ones. The CUDA Toolkit should also match the GPU generation to enable all accelerated computing functionalities efficiently. Regular firmware and software updates help maintain stability post-upgrade.​

Post-Migration Optimization

Maximize performance on H100 by:

- Utilizing AI workload optimizations specific to H100 such as Transformer Engine and FP8 precision.

- Monitoring GPU thermal performance and power consumption using Cyfuture Cloud’s management tools.

- Adjusting resource allocation based on application demands.

- Leveraging Cyfuture’s high-speed networking and scalable storage solutions to avoid bottlenecks.​
