Parallel是一个并行编程库，提供了一种简化并行处理的方式，如并行循环、迭代和任务。Parallel通过自动化任务的拆分和分配，利用多个线程并行执行任务，以提高处理大量数据和计算密集型任务的效率。Parallel使用并行循环（Parallel.For、Parallel.ForEach）、并行迭代（Parallel.Invoke）和任务并行（Parallel.Invoke、Parallel.Fo...
Parallel.For循环 在 System.Threading.Tasks 名称空间下,会为循环对象自动创建多个线程并行循环,因此是无序的。 1 publicstaticParallelLoopResult For(intfromInclusive,inttoExclusive, Action<int> body); fromInclusive:开始索引(含) toExclusive:结束索引(不含) body:将为每个迭代调用一次的委托 usingSystem;using...
Parallel.For(0, data.Count, (i) => { Thread.Sleep(500); if (ShowProcessExecution) Console.WriteLine(data[i]); }); DateTime dt2 = DateTime.Now; Console.WriteLine("并行运算For运行时长:{0}毫秒。", (dt2 - dt1).TotalMilliseconds); } /// /// 这是并行计算ForEach /// private void...

1、Parallel.For()方法 Parallel.For(int fromInclude, int toExclude, Action<int> body) 与for循环类似,执行并行的循环,相当于每次循环一个线程 官方文档:https://docs.microsoft.com/zh-cn/dotnet/api/system.threading.tasks.parallel.for?redirectedfrom=MSDN&view=netframework-4.7.2 ...
或者再整点OpenMP 4.0的SIMD（这个MSVC是以extension的形式支持的）：#pragma omp parallel forfor(size...
for (i=0; i < 100; i++) { a[i] = a[i] + b[i]; /* S1 */ } /* L2: another short parallel loop */ for (i=0; i < 100; i++) { b[i] = a[i] * d[i]; /* S2 */ } 这两个短并行循环彼此相邻,可以安全地合并,如下所示: ...

一个原则是:应该尽量少的使用parallelfor, 因为parallel for也需要时间开销。即: (1)如果外层循环次数远远小于内层循环次数,内层循环较多时,将parallel for加在内层循环。 示例代码: int a=0; int b=0; inline void openmpTest2(int thread_num) {
