nvcc是与CUDA Toolkit一起安装的CUDA compiler-driver tool,它只知道它自身构建时的CUDA runtime版本。它不知道安装了什么版本的GPU driver,甚至不知道是否安装了GPU driver。 综上,如果driver API和runtime API的CUDA版本不一致可能是因为你使用的是单独的GPU driver installer,而不是CUDA Toolkit installer里的GPU d...

参考:显卡,显卡驱动,nvcc, cuda driver,cudatoolkit,cudnn到底是什么? 如果从零开始安装的话,需要注意要安装的东西之间的关系,从下到上依次是NVIDIA-Driver,CUDA,cuDNN。 NVIDIA-Driver是显卡驱动,这个是直接和显卡硬件打交道的,所以它是最底层的。 CUDA(Compute Unified Device Architecture,统一计算架构)是由NVIDIA...
cmake-DCUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda-10.2 常规的配置修改 修改arch参数,改为compute_50,由于是CMakeList.txt构建的,所以这次在这里修改。之后,修改对应的模块路径,修改简单的引用错误。 make系列错误 做完以上操作后,cmake命令就基本没问题了,这里我们需要继续make,但是make到[66%]左右时会出现错误如下...
首先,为了符合ELF规范,cuda toolkit 所有11.x的release的SONAME都保持一样(除了NVRTC),这样以来,当你的程序基于cuda toolkit11.1库进行动态链接编译后,然后程序放到cuda toolkit 11.0的环境中,动态链接器首先不会因为SONAME而发难。但是,SONAME这一关过去后,如果cuda toolkit 11.1中有11.0中不具备的符号又该怎么办呢?
