复杂算术CUDA [英] Complex arithmetics in CUDA

问题描述

我经常在CUDA中使用复杂的算术，需要定义自己的实现，例如超越函数（ sin ， cos ， exp ，...）。我想现在通过编写一个这样的函数库来考虑一个大数量的情况，避免任何时候为新的实现陷入停顿来确定解决问题。

I frequently use complex arithmetics in CUDA and need to define my own implementations of, for example, transcendental functions (sin, cos, exp, ...) on complex numbers. I want now to definitely solve the problem by writing a library of such functions so to consider a "large" number of cases and avoiding being pit-stopped any time for new implementations.

我知道，对于其中一些，代码编写可能是不平凡的角度来看，在精度和计算复杂性之间的权衡。不过，我也知道C ++有自己的复杂的数学库。

I'm aware that for some of them, code writing could be non-trivial from the point of view of trade-off between accuracy and computational complexity. Nevertheless, I'm also aware that C++ has its own complex math library.

是否有可能为CUDA目的回收现有的C ++解决方案？

Is there any possibility to "recycle" already existing C++ solutions for CUDA purposes?

推荐答案

可能你已经找到答案，但这里是我的：

Probably you already found the answer, but here is mine:

有可能回收复杂C ++ ISO库的来源

UPD：

我想你可以尝试与作者合作：

I think you can try to collaborate with the author of:

用于CUDA设备的C ++ std :: complex的实现（即使用nvcc编译）
