- 24 Sierra release: December 2017
- 25 Infrastructure nodes are first
- 26 Linux • Firmware • Systems • GPU interfaces
- 27 24 Core SMT4
- 28 8 Billion transistors
- 29 POWER9 is major refresh POWER
- 30 Major Architectural changes: • Radix/Linux Based MMU • New interrupt controller • Direct attach DDR4 DIMMs
- 31 New Slice Microarchitecture
- 32 First through 14nm fab
- 33 POWER9 chip development
- 34 Minor releases too
- 35 DD1: January 2017
- 36 Planning for Linux and Firmware
- 37 Design: Radix MMU
- 38 Radix MMU: • Simpler • Better performance • KVM allocations
- 39 Simulation: • Functional • Cycle Accurate
- 40 Teach Linux basic feature
- 41 Bringup: Everything is broken
- 42 Get Linux up
- 43 Bringup: • Identify issues • Work around • Get out of the way • Find real fix
- 44 Develop items that need real hardware
- 45 Testing • More systems • Systems getting more sophisticated • Devs - Machines futher separated
- 46 Release: Yay!
- 47 Staged release
- 48 POWER9 not backwards compatible with POWERS
- 49 IBM - RedHat strong relationship
- 50 IBM & RedHat partnered on RHEL7 for POWERS
- 51 Deliver Linux to customers
- 52 End of Moore's Law
- 53 Drive accelerators
- 54 Binary Linux kernel driver
- 55 Helped prove out: • Link training • Firmware
- 56 Coherent memory
- 57 CUDA Unified memory
- 58 Design • IOMMU looks like PCle ATS • IOMMU directly uses Radix MMU
- 59 Simulation with P9
- 60 Bringup: March 2017
- 61 Testing: Data integrity
- 62 Baseboard Management Controller
- 63 Little computer that turns on your big computer
