Profiling / Profiler

• Java
  • ​Eclipse Test & Performance Tools Platform Project (TPTP) - Eclipse 的 Profiling 工具
    • ​An introduction to profiling Java applications
    • ​Overview of the Profiling Tool - Eclipse 說明文件有蠻詳細的 Monitoring and profiling applications 觀念與操作步驟介紹
  • ​Netbean Java Profiler - CPU, memory and threads profiling - 搭配 Netbean
  • ​JProfiler - ​維基百科 - 搭配 Eclipse
  • ​jmp
    • ​Debian 套件 tijmp - Profiler for Java to trace object and method timings
    • ​Debian 套件 jmp
  • Runtime Profiler
    • ​http://profiler4j.sourceforge.net/ - 看起來不錯，不過大約 2006 之後就比較少更新了。
  • Monitoring - JMX
    • ​JMeasurement - 支援 JMX 的 Profiler
  • ​xdprof - a cross-platform tool that captures and analyzes stack traces sent at a fixed interval from Java Virtual Machines in a distributed system - 因為是針對分散式系統的 profiler，所以有可能可以用在 Hadoop 效能分析上

• C - check slides of "Advanced C Programming - Pro?ling"
  • ​gprof - 屬於 GNU binutils 的一部分 - ​Debian 套件 - binutils
    • ​gprof 看performance分析…
  • gcov
  • ​valgrind - ​Debian 套件 - valgrind - (2010-03-04)
    • ​檢查程式記憶體的小工具-valgrind
    • ​Detecting C/C++ memory leaks with valgrind
    • 在 slides of "Advanced C Programming - Pro?ling" 投影片介紹中，有三個主要工具 memcheck、cachegrind、callgrind
      • cachegrind - 模擬 L1/L2 Cache, 找出 cache misses
        • ​Debian 套件 kcachegrind - visualisation tool for valgrind profiling output
        • ​Debian 套件 kcachegrind-converters - format converters for KCachegrind profiling visualisation tool
      • callgrind - 紀錄函數呼叫圖(call graph)
  • ​oprofile - a system-wide profiler for Linux systems, capable of profiling all running code at low overhead.
    • 有 ​Debian 套件 - oprofile

      ~# opcontrol  --init        # to load module and daemon
      ~# opcontrol  -s            # to start sampling
      ~# opcontrol  -t            # to stop sampling
      ~# opcontrol  --dump        # ?ushes the event log
      ~# opcontrol  --list-events # shows available performance counters
      ~# opreport  -l  prog-name  # gives breakdown of samples per function in prog-name
      

• Perl
  • ​Devel::Profile - ​Debian 套件 - libdevel-profile-perl - a Perl code profiler

• PHP - references for armorize
  • ​PHP Performance Profiling
  • ​php-profiler

• Python
  • ​Debian 套件 python-profiler - deterministic profiling of any Python programs

• Ruby
  • ​Debian 套件 ruby-prof - A fast code profiler for Ruby

• C# / Mono
  • ​mono-profiler - Mono profiler - ​有 Debian 套件 mono-profiler

Microcontroller (MCU, PIC)

• 先前來演講的 Xavi 談到要徵人幫忙把
• ​SDCC - Small Device C Compiler - ​Debian 套件 sdcc
• ​Piklab - IDE for PIC microcontrollers - an integrated development environment (IDE) for applications based on Microchip PIC and dsPIC microcontrollers similar to the MPLAB environment. - 類似 Microchip 官方 MPLAB 的整合開發環境 - 有 ​piklab 的 Debian 套件
• ​gpsim - Simulator for Microchip's PIC microcontrollers - ​Debian 套件 gpsim
• ​gputils - ​Debian 套件 gputils - utilities for the Microchip PIC microcontrollers family contain an assembler (compatible with MPASM), a disassembler, and other tools.
• ​FreeRTOS - a portable, open source, royalty free, mini Real Time Kernel - 先前就有紀錄過用單晶片上執行 linux 系統，這個專案也是可以執行在很多家的單晶片上。
