GPU computation error: please help

1 次查看(过去 30 天)
HI all, I want to use GPU in my research. I downloaded simple example from mathworks (code is attached). Basically, code is:
A = magic(5000);
AonGPU = gpuArray(A);
f = ones(1,20)/20;
BonGPU = filter(f, 1, AonGPU);
On the last line there is an error:
Error using parallel.gpu.GPUArray/filter An unexpected error occurred trying to launch a kernel. The CUDA error was: CUDA_ERROR_INVALID_VALUE.
Error in ex_gpu (line 14) BonGPU = filter(f, 1, AonGPU);
Can someone help please? My GPU is NVIDIA GeForce GTX 650 Ti (According to device manager), Windows 7 64 bit. I've installed the latest driver, as listed here http://www.mathworks.com/products/availability/index.html#DM
Thanks!

Also command A = rand(M,K,'gpuArray'); doesn't work:
Error using rand Output class must be 'single' or 'double'.

请先登录,再进行评论。
