Hi, I have a simple test program using an image3d with CL_UNSIGNED_INT8 data in it. When I use the following sampler my test program works fine.

sampler_t trilinear_sampler = CLK_FILTER_LINEAR | CLK_NORMALIZED_COORDS_FALSE | CLK_ADDRESS_CLAMP_TO_EDGE;

But if I switch to :

sampler_t trilinear_sampler = CLK_FILTER_LINEAR | CLK_NORMALIZED_COORDS_FALSE | CLK_ADDRESS_CLAMP;

then the sampling seems to be done using Nearest and not Linear.

I have attached the driver Info for my configuration below.

Well, I think that this is my first post on the forum so hi! to everyone.

I have an issue when debugging an OpenCl kernel, when I try to enter a function declared outside it and invoqued inside the kernel I have the following error:

First-chance exception at 0x763cc41f in OpenCL_EGS.exe: Microsoft C++ exception: OclSocketError at memory location 0x02dff9f0..
The thread 'Win32 Thread' (0x11b4) has exited with code -1 (0xffffffff).

Hello everyone.

When I was using the image2D objects to optimize my application, there was a strange phenomenon happened. 

I have set the width and the height of the image2D buffer and the performance would increase as the height increase while the width decrease.

However, after I modified my opencl code to try another implementation and then restore the code to its status before modification, the performance was slower than before. And the performance would increase as the height decrease while the width increase.

Hi,

I'd like to know what the interoperability status is between Intel OpenCL and TBB.  In specific, can I look forward to problems (or not) if I make calls to Intel OpenCL from within TBB tasks?  Do I have to worry about oversubscription (will they use the same thread queue)?  Do I have to worry about which version of TBB I use with which version of OpenCL.  Sorry if this is answered somewhere in the docs already, I couldn't find it.

Thanks,

David
