Customer Testimonials

"Using Ampere A1 instances on OCI with integrated Ampere Optimized AI library, we managed to right-size compute providing price-performance advantage on deep learning inferencing relative to GPUs and to other CPUs. We found an order of magnitude or more reduction in cloud resource costs, measured at 4 operating points for 2 cloud vendors, while avoiding operational complexity for changes in model serving resource needs and cloud offerings."

-Madhuri Yechuri, CEO, Elotl

Ampere Optimized AI

Ampere Altra and Ampere Altra Max, with high performance Ampere optimized frameworks, offers the best-in-class Artificial Intelligence inference performance for all AI applications developed in the most popular frameworks including PyTorch, Tensorflow, and ONNXRuntime. Ampere Model Library (AML) offers pretrained models to help accelerate AI development.

Ampere helps customers achieve superior performance for AI workloads by integrating optimized inference layers into common AI frameworks.

Main Components

  • Framework Integration Layer: Provides full compatibility with popular developer frameworks. Software works with the trained networks “as is”. No conversions or are required.

  • Model Optimization Layer: Implements techniques such as structural network enhancements, changes to the processing order for efficiency, and data flow optimizations, without accuracy degradation.

  • Hardware Acceleration Layer: Includes a “just-in-time”, optimization compiler that utilizes a small number of Microkernels optimized for Ampere processors. This approach allows the inference engine to deliver high-performance on all frameworks.

Native FP16 Support

Ampere hardware uniquely offers native support of the FP16 data format providing nearly 2X speedup over FP32 with almost no accuracy loss for most AI models.

FP16, or "half-precision floating point," represents numbers using 16 bits, making computations faster and requiring less memory compared to the FP32 (single precision) data format. The FP16 data format is widely adopted in AI applications, specifically for AI inference workloads. It offers distinct advantages, especially in tasks like neural network inference, which require intensive computations and real-time responsiveness. Utilizing FP16 enables accelerated processing of AI models, resulting in enhanced performance, optimized memory usage, and improved energy efficiency without compromising on accuracy.
