是否有可能具有数量不同的CUDA内核?

本文介绍了是否有可能具有数量不同的CUDA内核?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我想制作一个内核，它带有许多未设置的参数.这可能吗?

I would like to make a kernel which takes a number of arguments, that is not set. Is this possible?

我猜这行不通吗?但为什么?

I guess this does not work? But why?

推荐答案

如果您要询问典型的C风格变量，则不可以.

if you are asking about typical C style vargs, then no.

但是，因为内核支持C ++链接，所以存在一些模板和名称修饰技巧，可用于实例化具有长度和不同类型的参数列表的内核的不同版本.还请注意，CUDA 7.0引入了C ++ 11可变参数模板支持.

But because kernels support C++ linkage, there are template and name mangling tricks which can be used to instantiate different versions of a kernel with length and different types of argument lists. Note also that CUDA 7.0 introduces C++11 variadic template support.

因此，有很多选择可以做到这一点，但可能不是您问问题时所想到的那些选择.

So there are options to do this, but probably not the ones you were thinking of when you asked the question.
