driver bug: opencl recursive blur fail on lastest graphic driver

[Jzhan59]

Hi all

I download the opencl recursive blur sample from Nvidia at http://developer.download.nvidia.com/compute/DevZone/OpenCL/Projects/oclRecursiveGaussian.zip http://developer.download.nvidia.com/compute/DevZone/OpenCL/Projects/oclRecursiveGaussian.zip. it run ok on AMD graphic card and Nvidia graphic card. When running the sample on Intel CPU, the result is as expected, but when running the kernel on Intel HD 4000 GPU, it fail. I run into this problem when update the graphic driver to the lastest version. The sample binary run as expected with the driver before version 15.31.3.3071.

Does anybody know anything about this problem? Will next driver version fix this driver issue

Hello lukejr,

Note that we have developed a newer driver for the Intel® HD graphics 4000.

Can you please try the latest driver and let me know if issue persists?

It can be downloaded at the following link:

Hi Kevin,

I have test the last driver(version:9.18.10.3165, installer: Win64_15319.zip) before I post this thread. As I have said in previous post. When run the sample on CL_DEVICE_TYPE_CPU OpenCL device of Intel 3rd Core processor, the result is as expected. However when change the OpenCL device to CL_DEVICE_TYPE_GPU on Intel HD 4000, the sample give incorrect result.

In case that issue persists, I need you to provide the following:
