OMP_GET_MAX_THREADS 目的: 获取通过OMP_GET_NUM_THREADS能够得到的最大线程数量。 说明: 1.通常这个最大数量由omp_set_num_threads()或OMP_NUM_THREADS环境变量决定。 2.可以在串行或并行区域调用。 OMP_GET_THREAD_NUM 目的: 获取线程在team内的ID,返回值在0到omp_get_num_threads()-1之间。主线程(maste...

The omp_set_num_threads routine specifies the number of threads to use for the next parallel region by setting the first value of num_list for the OMP_NUM_THREADS environment variable. The number_of_threads_expr argument is evaluated, and its value is used as the number of threads. If ...
omp_set_num_threads功能设置线程的默认周期数为未指定num_threads子句的后续并行区域使用。格式如下所示: 复制 #include <omp.h> void omp_set_num_threads(int num_threads); 参数num_threads 的值必须是正整数。其效果取决于线程数动态调整是否启用。有关全面设置有关交互的规则线程的omp_set_num_threads功能...

针对你遇到的“undefined reference to omp_set_num_threads'”问题,这通常是由于编译器在链接阶段未能找到omp_set_num_threads`函数的定义。该函数是OpenMP库的一部分,用于设置并行区域中使用的线程数。以下是针对此问题的详细分析和解决步骤: 确认omp_set_num_threads函数的来源: omp_set_num_threads函数属于OpenM...
