Truncation of Float to Half in Intel Run Time Driver using OpenCL 2.0

Hello,

    The latest OpenCL Intel driver download uses OpenCL 2.0 and seem to truncate Floating point values to half values.  Does anyone know a workaround or a way to get a version of Intel openCL drivers that do not do this truncation?

Thanks,

Hi Raghu,

Which Intel processor are you running on? Which OS? Which version of the driver are you using? Do you have a reproducer that clearly shows the issue?

Hi Robert, we use i5 or i7 destops running win 8.1.  We downloaded the latest openCL driver from the link I sent that uses openCL 2.0.  You can use the pair programming box to reproduce the problem.  Thanks, Raghu

Hi Raghu,

I am not familiar with the pair programming box - what is it? Is it a reproducer? Could you provide a link?

Thanks!
