VS2005中有支持Openmp的选项开关

改下OpenMP支持

[IntelPerLib]

Thread Check 与 Thread Profiler 都可以检测OpenMP threading的程序.

-tcheck generate instrumentation to detect multi-threading bugs
(requires Intel(R) Thread Checker; cannot be used with
compiler alone)
-tprofile generate instrumentation to analyze multi-threading
performance (requires Intel(R) Thread Profiler; cannot
be used with compiler alone)
-openmp enable the compiler to generate multi-threaded code
based on the OpenMP directives
-openmp-profile link with instrumented OpenMP runtime library to
generate OpenMP profiling information for use with the
OpenMP component of the VTune(TM) Performance Analyzer
-openmp-stubs enables the user to compile OpenMP programs in
sequential mode. The openmp directives are ignored and
a stub OpenMP library is linked (sequential)
-openmp-report{0|1|2} control the OpenMP parallelizer diagnostic level


在编译器(intel)中有关于openmp的不同参数，可以根据实际需要配合vtune等工具

多线程的程序，都不是很好测试的

[flyingdog]

随着工具的发展，开发多线程程序将变得越来越容易。

那也比单线的要难调得多
