瞭解如何在 .NET 中撰寫 Parallel.For 迴圈,而您不需要取消迴圈、中斷迴圈的反覆項目,或維護任何執行緒區域狀態。
Parallel.For是一个静态方法,用于并行化for循环。例如: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 Parallel.For(0,10,i=>{Console.WriteLine(i);}); 这段代码会打印数字0到9。由于此循环是并行的,所以数字可能不按顺序打印。 2. Parallel.ForEach ...
cv::parallel_for_函数是OpenCV并行框架的核心。该函数允许我们并行执行循环,每个循环迭代可以在不同的线程上执行。cv::parallel_for_函数接受一个cv::Range对象和一个实现了cv::ParallelLoopBody接口的对象。 cv::parallel_for_(cv::Range(0, count), MyParallelLoopBody()); 其中,MyParallelLoopBody需要实现...
使用parallel_for必须保证循环的迭代可以以任何顺序并行执行,且彼此安全。TBB库不会检查并行执行parallel_for(或实际上任何通用算法)的迭代是否会生成与算法串行执行相同的结果。 例子:并行矩阵乘法 计算MxM矩阵的C = AB 首次遍历内层k循环以计算C矩阵单个元素时所遍历的元素 ...
