Cuda自带的thrust没有 <thrust/universal_vector.h>文件 #30

Open riverandroad opened 7 months ago

riverandroad commented 7 months ago

08/06_thrust/01/main.cu文件里面include <thrust/universal_vector.h>显示找不到 <thrust/universal_vector.h> 官方thrust库里面的"universal_allocator.h", "universal_ptr.h", "universal_vector.h"都没有在我电脑cuda的include的文件夹里面。是我安装cuda有问题吗？（2022年安装的cuda）还是更新了吗？#include <thrust/device_vector.h> #include <thrust/host_vector.h>这些没有问题。

你可以告诉我cuda版本号，不用告诉我几几年的

11.1版本的cuda，nvcc --version后，显示是：

nvcc: NVIDIA (R) Cuda compiler driver Copyright (c) 2005-2020 NVIDIA Corporation Built on Mon_Oct_12_20:09:46_PDT_2020 Cuda compilation tools, release 11.1, V11.1.105 Build cuda_11.1.TC455_06.29190527_0

@archibate 暂时找到问题了，小彭老师，应该是因为cuda版本太旧了。看Thrust release的网站

Thrust 1.12.0 is the major release accompanying the NVIDIA HPC SDK 21.3 and the CUDA Toolkit 11.4.

It includes a new thrust::universal_vector, which holds data that is accessible from both host and device. This allows users to easily leverage CUDA's unified memory with Thrust.
