Apple CHUD Tools - 4.1.0

The Computer Hardware Understanding Developer Tools (CHUD Tools) are designed to help hardware and software developers measure and optimize the performance of PowerPC Macintosh systems running their products under MacOS X: Shark is a source line level profiling tool which shows you where time is being spent (both user and supervisor code), and correlates performance events to your program's code. It also supplies tuning advice about how to improve the performance of your code on the G4 and G5 processors. MONster provides direct access to performance counters and presents the data in both spreadsheet and chart form. Saturn is an exact, function-level profiler with which you can generate and view a complete function call trace of your application. Reggie SE allows you to view the contents of PowerPC special purpose registers as well as PCI configuration registers. The CHUD Tools suite also includes several additional tools for benchmarking and hardware related development.

Shark - source line level profiling tool which shows you where time is being spent (both user and supervisor code), and correlates performance events to your program's code

MONster - provides direct access to performance counters and presents the data in both spreadsheet and chart form

Reggie SE - allows you to view the contents of PowerPC special purpose registers as well as PCI configuration registers

Saturn - exact, function-level profiler with which you can generate and view a complete function call trace of your application

BigTop - graphing front-end to top and vm_stat useful for monitoring system performance

PMC Index - search tool for finding performance counter events and their setup

CacheBasher - measures memory hierarchy performance under a wide range of conditions

Skidmarks GT - processor benchmark which measures integer, floating-point and vector performance

Spindown HD - monitors the power state of drives connected to the system

CPU.pref - enable/disable second processor on dual processor machine on the fly

acid - analyzes instruction traces and presents detailed analysis and histogram reports

amber - captures the instruction and data address stream generated by a processes running in MacOS X, and saves it to disk in TT6, TT6E or FULL format.

chudRemoteCtrl - command line tool for remotely starting MONster or Shark.

monster - scriptable command line version of MONster

shark - scriptable command line version of Shark

simg4 - PPC7400 simulator

CHUD.framework - programmatic access to many of the features of the CHUD tools
