Using Metal 2 for Compute - Thursday

Session video and resources: https://developer.apple.com/videos/play/wwdc2017/608/

MPS (Metal Performance Shader)

• MPS is now supported on macOS as well

Image Processing

Linear Algebra

Accelerating ML Using MPS

Training & Inference

• Training to classify images -> Inference via CNN (Convolutional Neural Network)
  • First part is one time, highly time consuming training phase
  • Second part could be accelerated by using MPS

Convolutional Neural Networks

Neural Network Graph API

• Describe neural networks using graph API
• Initialize once, reuse
• Execute graph on GPU with single call

Summary

• GPU accelerated primitives
  • Extended support for image processing
  • Addes support for linear algebra
• Optimized for iOS and macOS
• New neural network graph API
