Question

对于像gtx1080这样的特定gpu，我想知道哪个cuda工具包版本支持它。我已经扫描了nvidia的官方网站，但没有找到具体的结果。

Answer 1

您可以先在以下站点查看GTX1080的计算能力（CC）。这是CC 6.1。

https://developer.nvidia.com/cuda-gpus

然后检查下面的CUDA文档，看它是否在当前版本的CUDA 7.5的受支持的CC列表中。事实并非如此。

http://docs.nvidia.com/cuda/cuda-c-programming-guide/index.html#compute-capabilities

所以它应该得到未来版本的支持。目前即将发布的版本是CUDA 8.您可以在其文档中找到它。

如果您不确定doucments的版本，可以找到与特定CUDA安装相关的文档，例如

/usr/local/cuda-7.5/doc

CUDA编译器的帮助消息也提供了支持的CC列表。

$ nvcc --help
--gpu-code <code>,...                      (-code)                           
        Specify the name of the NVIDIA GPU to assemble and optimize PTX for.
        nvcc embeds a compiled code image in the resulting executable for each specified
        <code> architecture, which is a true binary load image for each 'real' architecture
        (such as sm_20), and PTX code for the 'virtual' architecture (such as compute_20).
        During runtime, such embedded PTX code is dynamically compiled by the CUDA
        runtime system if no binary load image is found for the 'current' GPU.
        Architectures specified for options '--gpu-architecture' and '--gpu-code'
        may be 'virtual' as well as 'real', but the <code> architectures must be
        compatible with the <arch> architecture.  When the '--gpu-code' option is
        used, the value for the '--gpu-architecture' option must be a 'virtual' PTX
        architecture.
        For instance, '--gpu-architecture=compute_35' is not compatible with '--gpu-code=sm_30',
        because the earlier compilation stages will assume the availability of 'compute_35'
        features that are not present on 'sm_30'.
        Allowed values for this option:  'compute_20','compute_30','compute_32',
        'compute_35','compute_37','compute_50','compute_52','compute_53','sm_20',
        'sm_21','sm_30','sm_32','sm_35','sm_37','sm_50','sm_52','sm_53'.

如何知道支持一个特定gpu的最低cuda工具包版本，如gtx1080
