The omp_get_max_threads routine returns an upper bound on the number of threads that could be used to form a new team if a parallel region without a num_threads clause were encountered after execution returns from this routine。 很清楚的说明了,这个”最大数量“是指在不使用num_threads的情况...

Using OpenMP, you have basically 3 different ways of specifying the number of threads to use in a parallel region: The most commonly used one is the environment variable OMP_NUM_THREADS which needs to be set in the code's environment prior to running it for being effecti...

Hello, Is there any way to specify the number of OpenMP Threads for the Hypre library? I know one can use set omp_num_threads= in the command window but I would like to hard-wire the number of threads. FYI, my codes are in Fortran and I am using Windows. Thank you....
