带有 CUDA 安装问题的 Openmpi

Question

在尝试安装支持 CUDA 的 Openmpi 时，我遇到了一些生成文件失败的问题。

btl_uct_module.c: In function ‘mca_btl_uct_reg_mem’:
btl_uct_module.c:214:22: error: ‘UCT_MD_MEM_ACCESS_REMOTE_GET’ undeclared (first use in this function)
         uct_flags |= UCT_MD_MEM_ACCESS_REMOTE_GET;
                      ^

                     ^

我是用下面的命令配置然后安装的

./configure --prefix=/home/$USER/.openmpi --with-cuda
make all install

我正在使用以下配置：

Ubuntu 16.04

Cuda 10.1

CuDNN 7.5

Openmpi 4.0.1

奇怪的是，我试图在我的本地机器上进行相同的安装，其中有 Ubuntu 18.04，它安装并运行良好。这是一些兼容性问题吗？有什么想法吗？

Answer 1

原来是兼容性问题。使用 openmpi 3.1.4 解决了问题。
