int omp_get_num_threads (void); Purpose Returns the number of threads in the current region. Note The OpenMP Run-Time Library is available only in the LabWindows/CVI Full Development System. LabWindows/CVI determines the number of threads used for a parallel region by the following rules (in...
omp_get_num_threads函数属于OpenMP库。OpenMP是一个用于多平台共享内存并行编程的应用程序接口(API),支持C、C++和Fortran语言。 检查编译命令是否包含了该库的链接选项: 在编译和链接使用OpenMP函数的程序时,需要确保链接器能够找到OpenMP库。对于GCC编译器,这通常意味着需要在编译命令中添加-fopenmp选项。例如,如果你的...
$omp end parallel end 若是不声明OMP_GET_THREAD_NUM,OMP_GET_NUM_THREADS那么不会得到正确的线程号和总线程数。 原因:??? (2) 但是如果在开头使用"use omp_lib",则不需要声明。 但是在某些程序中还是得到 线程数 线程号为浮点数的现象 ??? 原因:子程序里面没有重复声明use omp_lib....

N2 = omp_get_num_threads() PRINT *, N2 !$OMP END PARALLEL END Theomp_get_num_threadscall returns 1 in the serial section of the code, so N1 is assigned the value 1. N2 is assigned the number of threads in the team executing the parallel region, so the output of the second print...
omp_get_num_threads函数返回当前线程的数目在执行调用的并行区域的团队。 格式如下所示: #include <omp.h> int omp_get_num_threads(void); num_threads子句、omp_set_num_threads功能和OMP_NUM_THREADS环境变量控制线程数。团队。 如果线程的数目尚未由用户显式设置,默认实现中定义。 此函数绑定到最接近的封闭...
