kernel cannot be vectorized #70

Closed malharjajoo closed 5 years ago

Hi,

On running my executable in succession I keep getting an clEnqueueWriteBufferException on random runs. On catching the exception and printing the error, it says kernel cannot be vectorized. (Even though this happens, the version passes the automated tests in the log folder )

My question is, is it possible to get this exception on running the same executable in quick successions ? Could this be something to do with inability of GPU to execute kernels in quick succession ?

Thanks!

Hrmm, I don't think I have ever seen that error before.

What platform/provider/GPU/OS are you using?

My initial suspicion is that it would be a software provider which is trying to vectorise to use SSE/AVX, but that wouldn't fit with the symptom of repeated executions causing the errors.

I am using - GPU = Intel HD Graphics OS = Ubuntu 16.04
