This document discusses IBM's PowerAI platform for deep learning. It provides the following key points: 1. PowerAI is built on open source tools and IBM's POWER processors to provide an enterprise-ready software distribution for data scientists to develop deep learning models faster. 2. The Power9 CPU architecture features NVLink connections that provide faster GPU-CPU bandwidth compared to PCIe, allowing PowerAI to support larger and more complex deep learning models. 3. PowerAI with distributed deep learning capabilities can scale to train models on 256 GPUs, achieving a 58x speedup compared to a single system for image classification tasks.
