Accelerator_view 指定的数组位置的对象。_Extent
在每个数组维度的范围。_E0
这一部分的范围内的最重要的组件。_E1
这一部分的范围内的下一步-到-最高有效的组件。_E2
这一部分的范围内的最不重要的组件。InputIterator
输入的 interator 的类型。_Src
若要复制的对象。_Src_first
到源容器开始迭代器。_Src_last
结束迭代器中的源容器。_Other
其他数据源。_Rank
部分中的排位。_Value_type
复制的元素的数据类型。
备注
临时构造函数有两个 accelerator_view 作为构造函数的参数的对象。临时数组作为提示用于优化之间 （CPU 和 Direct3D 加速） 之间的两个加速键的重复的副本。临时数组为数据传输进行了优化，并且没有稳定的用户空间内存。它们提供支持，具有正确的硬件的对齐方式以确保有效地直接内存访问 (DMA) 传输之间的 CPU 和加速器 DirectX 临时缓冲区。accelerator_view临时数组的属性返回它已与构造的加速器第一个参数的值。不能更改或检查临时数组的内容，如果它涉及在传输操作中，如下面的代码所示。
class SimulationServer
{
array<float,2> acceleratorArray;
array<float,2> stagingArray;
public:
SimulationServer(const accelerator_view& av)
:acceleratorArray(extent<2>(1000,1000), av),
stagingArray(extent<2>(1000,1000), accelerator("cpu"),
accelerator("gpu"))
{
}
void OnCompute()
{
array<float,2> &a = acceleratorArray;
ApplyNetworkChanges(stagingArray.data());
// Starting here, you can't change or examine contents.
a = stagingArray;
parallel_for_each(a.extents, [&](index<2> idx)
{
// Update a[idx] according to simulation.
}
stagingArray = a;
// Starting here, you can change or examine contents.
SendToClient(stagingArray.data());
}
};
