CL_DEVICE_MAX_WORK_ITEM_SIZES on Intel core i3

[Abs_S]

Hi All,

When i discovery devices (after intstalling openCL intel SDK). I am getting following output...
Why is the CL_DEVICE_MAX_WORK_ITEMS_SIZES are reported 0 / 0 / 0 - what does it mean? could you pls explain whether following output is correct?

Hi,

Can you please post the code that queries this values?
What is the return value you have from the function?

Also the values for WIDTH/HEIGHT/DEPTH are wrong.
Thanks,
Evgeny

Thanks Evgeny for your reply. I am using JOCL wrapper. I am running samples fromhttp://www.jocl.org/samples/samples.htmlesp.JOCLDeviceQuery. Your answer seems to suggest that the problem is in JOCL implementation.
