I’ve encountered several problems when installing CUDA in my computer. Now when validating the result from deviceQuery CUDA Sample, there is no error and I got this result:

deviceQuery, CUDA Driver = CUDART, CUDA Driver Version = 5.5, CUDA Runtime Version = 5.5, NumDevs = 1, Device0 = GeForce GTX 660M
Result = PASS[/b][/i]

BTW, my device is “GeForce GTX 660M”

and then I wanted to test bandwidthTest program, but I got an error :

[i]LINtekiiMac:release linyu$ ./bandwidthTest
[CUDA Bandwidth Test] - Starting…
Running on…

Device 0: GeForce GTX 660M
Quick Mode

CUDA error at bandwidthTest.cu:719 code=2(cudaErrorMemoryAllocation) “cudaEventCreate(&start)”
[/i]

Can anyone help me solve this problem? Thank you very much!

Which OS and driver did you install? Could you plase run deviceQuery_drv and provide the log?

My computer version is os X 10.8.4 and I installed CUDA-5.5 and cudadriver-5.5.24.

Run ./deviceQueryDrv :

LINtekiiMac:release linyu$ ./deviceQueryDrv

Actually, I just test the bandwidthTest program and it runs successfully. I don’t know why it happens, but it just works out.

Thank you for your reply very much!

Once again, a restart fixed this problem for anyone that wasn’t aware of the other threads.

It’s just so funny because I couldn’t find any other results for something similar other than the two other posts made, and they were all made within the span of a few days of each other.
