这将设置 ompnumthreads 为4,意味着并行区域将使用 4 个线程。在 Windows 系统中,可以在命令提示符中使用以下命令: cmd set OMP_NUM_THREADS=4 3. 在程序内部使用 omp_set_num_threads 函数设置线程数 除了在命令行中设置环境变量外,还可以在程序内部使用 omp_set_num_threads 函数来动态设置线程数。以下是...

In windows, you can set OMP_NUM_THREADS to NUMBER_OF_PROCESSORS, which is a system variable. Again, you can set this to any number, and you need to check which one gives the best performance, i.e again depending on the different functions, and also your data size etc.But, it...

Also, what is not known to me at this time is when in the first-level parallel section a team member requests n threads for then next parallel section it enters, if the Windows threads created on the 1st entry into the second level parallel section are persistent after exit of the section...
