• 1:15 – 3:15     Tutorial I: AMD’s "SimNow" Simulator, by Brian Barnes and John Slice

   

  SimNow:  A Fast and Functionally Accurate AMD X86-64 System Simulator

   

  Introduction

  SimNow Overview

  A.   Dynamic translation

  B.   1 IPC timing model.

  C.   Hosted on Windows64 and Linux64

  Goals

  A.   Performance target of 10x real hardware.

  B.   Software being simulated does not require any modifications and is not

   aware that it is being simulated.

                          C.  Should run on standard AMD64 based desktop/laptop systems with no

                                special hardware required.

                          D. Enhanced visibility into system operation – more than would be available

                               on hardware systems.

                          E.  System consistency checking.

   

  What Makes SimNow Different?

              Speed

              Capable of simulating a range of systems from a simple single-chip design to a full

  multi-processor PC

              Capable of simulating multiple PC systems at the same time.

              Implemented totally in software, no special hardware required

   

  How does SimNow Continue to Grow?

              Internal groups and partners add to device libraries and features which

              are then reviewed and then made available to all partners

   

  How is SimNow Used internally and by current partners?

              Used internally for trace and event collection to feed into timing accurate simulators, as

  well as to verify accuracy of retired instruction.

              Used internally to evaluate new instruction architectures.

  OS developer testing new chip features

              BIOS developer testing

              Software Product testing

              Hardware device modeling

   

  What is available in the Public Release of SimNow?

              Analyzer SDK

              1P 1Core and 1P 2core Platforms and Bios (with Pacifica support)

              Ready for user installation of operating system of choice

              Device SDK not included.

              Limited platform configuration capability.

   

  What if I am a AMD partner and want to do device Modeling or want

  to model other platforms?

              Need to request and sign a full SimNow license agreement

• 3:30 – 5:30    Tutorial II: Power5 Performance Measurement & Characterization, by Alex Mericas, IBM

POWER5 Performance Measurement and Characterization 

IBM's POWER5 is a dual core, Simultaneous Multithreaded (SMT) , superscalar processor using agressive speculation and out of order execution. Like most modern processors it has built-in Performance Monitoring capability to provide insight into hardware performance and to help tune software for optimum efficiency. This tutorial will provide an overview of the hardware facilities available on the POWER5 and the software tools to exploit those facilities. 

Alex Mericas is a Senior Technical Staff Member in IBM's Systems Technology Group. Alex designed the Hardware Instrumentation on the POWER4, POWER5, and PowerPC970 processors.
