Training Models in Half the Time with Cloud GPUs

As AI continues to revolutionize industries worldwide, the demand for faster and more efficient model training is ever-increasing. Cloud-based Graphics Processing Units (GPUs) have emerged as a game-changing solution, offering unparalleled computational power and scalability for training complex models. This blog post explores how you can optimize model training speed and efficiency by utilizing the latest GPU features on AI Cloud platforms.

Statistical Insights

• AI Training Compute Growth: AI training compute has been expanding at approximately 4x per year. This surpasses the peak growth rates of mobile phone adoption (2x/year, 1980-1987) and human genome sequencing (3.3x/year, 2008-2015), as mentioned in an article by Epoch AI.

• Hardware Efficiency: The peak FLOP/s per W achieved by GPUs used for ML training have increased by around 1.28x/year between 2010 and 2024.

• Manufacturing Capacity: GPU production is expected to expand between 30% to 100% per year through 2030. In a median projection, there is expected to be enough manufacturing capacity to produce 100 million H100-equivalent GPUs for AI training, sufficient to power a 9e29 FLOP training run.

Optimizing Model Training with Cloud GPUs

Key Strategies

• Increase Batch Size: Increasing the batch size is the first thing you should try if you’re dealing with low GPU usage while training. The available GPU memory constrains the maximum batch size, and exceeding it triggers an out-of-memory error.

• Mixed-Precision Training: Mixed-precision training is a technique employed in model training that utilizes different floating-point types (e.g., 32-bit and 16-bit) to improve computing speed and reduce memory usage while maintaining accuracy. NVIDIA GPUs with compute capability 7.0 or higher experience the most significant performance boost from mixed precision because they have dedicated hardware units for 16-bit matrix operations called Tensor Cores.

• Optimize Data Preprocessing: Structure the preprocessing pipeline into tasks that can be completed offline, i.e., at the data-creation phase before the training starts. Shifting operations to the data-creation phase will free up some CPU cycles during training.

• Disable Autoboost: If you're running an NVIDIA Tesla K80 GPU on Compute Engine, it is recommended to disable auto boost, using the following command (in Linux): sudo nvidia-smi --auto-boost-default=DISABLED. When using Tesla K80, you should also set the GPU clock speed to the highest frequency, using this command: sudo nvidia-smi --applications-clocks=2505.

Benefits of Using GPUs for Training Models in the Cloud

• Reduced Training Time: Cloud GPUs significantly reduce the time required to train complex models.

• Scalability: Cloud platforms offer the flexibility to scale GPU resources up or down based on your training needs.

• Cost-Effectiveness: Economical pricing models for cloud GPUs can be more cost-effective than investing in on-premises hardware.

• Accessibility: Cloud GPUs make powerful computing resources accessible to organizations of all sizes.
