基于C++及其扩展语言的动态剖析

程序优化是提高程序运行效率的重要步骤,程序剖析是程序优化的第一步。对于串行语言,程序剖析代码是由编译器通过一个命令行开关自动插入。但是,大部分并行语言编译器都不具有这个功能。该文以并行C++语言的可移植的动态剖析程序(profiler)为例,从两方面对问题进行了论述:首先给出实现可移植动态剖析程序的一般方法;然后分析一个用于pC++插桩(Instrumentation)工具。

A Dynamic Profiler for C++ and C++ Extension Languages

Program profiling is the first step in program tuning.For sequential languages,the necessary profiling code is automatically inserted by the compiler via a command line switch.however,not all compilers for parallel languages which are based on c++.The first part describes the general approach which allows portable and dynamic program profiling.The second part describes an instrumentation tool for PC++ which we implemented inserting the necessary profiling code in the program source.
