# TaskSystem::ParallelFor
|
||||
|
||||
```cpp
|
||||
template<typename Func>
|
||||
void ParallelFor(int32_t start, int32_t end, Func&& func)
|
||||
```
|
||||
|
||||
并行执行 for 循环。将循环范围划分为多个块,分配给多个工作线程并行处理。
|
||||
|
||||
**模板参数:**
|
||||
- `Func` - 可调用对象类型,签名为 `void(int32_t)`
|
||||
|
||||
**参数:**
|
||||
- `start` - 循环起始索引(包含)
|
||||
- `end` - 循环结束索引(不包含)
|
||||
- `func` - 对每个索引执行的函数
|
||||
|
||||
**返回:** 无
|
||||
|
||||
**复杂度:** O(n)
|
||||
|
||||
**分区策略:**
|
||||
- 根据 `std::thread::hardware_concurrency()` 确定线程数。
|
||||
- 将范围均分给各线程,每个线程处理连续的块。
|
||||
|
||||
**示例:**
|
||||
|
||||
```cpp
|
||||
// 并行处理 10000 个元素
|
||||
std::vector<float> data(10000, 0.0f);
|
||||
|
||||
TaskSystem::Get().ParallelFor(0, 10000, [&data](int32_t i) {
|
||||
data[i] = std::sin(i * 0.01f) * std::cos(i * 0.007f);
|
||||
});
|
||||
|
||||
// 并行矩阵乘法
|
||||
TaskSystem::Get().ParallelFor(0, N, [&matrix](int32_t row) {
|
||||
for (int32_t col = 0; col < N; ++col) {
|
||||
matrix[row * N + col] = Compute(row, col);
|
||||
}
|
||||
});
|
||||
```
