You can get the drivers from: http://www.nvidia.com/Download/index.aspx This may also arise due to permissions related issue, therefore try starting the matlab session as root or sudo user. You can also refer GPU CUDA problems: CUDA_ERROR_UNKNOWN - MATLAB Answers - MATLAB Central (mathwork...
CUDA_ERROR_UNKNOWN After this, Matlab does not recognize the GPU device anymore: the command gpuDevice results in: Errorusing gpuDevice (line 26) Anunexpected error occurred trying to retrieve CUDA device properties. The CUDA error was:
Theerror log was: <No information> TheCUDA error code was: CUDA_ERROR_UNKNOWN. It also fails to execute a kernel if I supply a pre-built one. My googling has indicated that >> reset(gpuDevice(1)) will reset things (I have a single GPU, nVidia 650m) but when I do that Matlab se...
1.报错 An unexpected error occurred trying to retrieve CUDA device properties. The CUDA error was: CUDA_ERROR_UNKNOWN 解决方法: 我gpu驱动是10.0以上且训练其他网络没出错过,但把代码放实验室工作站跑就没报错 根据MATLAB社区提示,可能是驱动版本造成报错,我将驱动版本由430升级到436.48(2019.10.1发布),成功...

在Matlab中使用GPU,要先输入gpuDevice命令初始化一下设备。 根据返回的信息能够大概估算出显存支持的最大数据。 否则使用时容易出现下面这样的问题: 错误使用 gpuArray An unexpectederroroccurred during CUDA execution. The CUDAerrorwas: unknownerror 如果出现这个问题,只能调小数组重启Matlab或者换个更好的显卡。

首先,你需要一个支持的GPU,目前仅支持Nvidia的GPU,不同版本的MATLAB对不同架构的GPU支持情况如下,带星号的需要重新编译CUDA。 可以用gpuDevice命令查看是否有支持的gpu,亮机卡GT 1030 也能支持。 GPU运算可以用两种方式实现, 用gpuArray和gather命令; 用GPU CUDA和MEX编程深度加速。
是因为MATLAB默认情况下不支持OpenMP多线程并行编程。OpenMP是一种用于共享内存并行编程的API,可以在循环、函数等代码块中使用指令来实现并行化。然而,MATLAB在编译Mex文件时默认不启用OpenMP支持,因此生成的Mex文件只会使用单个线程来执行。 要在MATLAB C Mex文件中启用OpenMP多线程并行编程,需要进行以下步骤: 确保您的...
