cuda - win32 的 cufft.lib 丢失

Question

我正在尝试使用 cuda 进行图像处理。

低通滤波器需要fft，所以尝试用cufft，现在发现“NVIDIA GPU Computing Toolkit\CUDA\v7.0\lib\win32”里面没有cufft.lib for win32。

它只存在于 x64 文件夹中。

我可以仅将袖带用于 x64 吗？还是我在安装时遗漏了什么？

来自 CUDA 7 release notes :

Certain CUDA Features on 32-bit and 32-on-64-bit Windows Systems

The CUDA Toolkit no longer supports 32-bit Windows operating systems. Furthermore, the Windows CUDA Driver no longer supports Tesla and Quadro products on 32-bit Windows operating systems. Additionally, on 64-bit Windows operating systems, the following features are no longer supported by the CUDA driver or CUDA toolkit:

• Running 32-bit applications on Tesla and Quadro products

• Using the Thrust library from 32-bit applications

• 32-bit versions of the CUDA Toolkit scientific libraries, including cuBLAS, cuSPARSE, cuFFT, cuRAND, and NPP

• 32-bit versions of the CUDA samples

所以不，从 CUDA 7 开始，Windows 平台上不再提供 32 位版本的 CUFFT。
