How to check the version of Intel OpenCL ? how to control number of cores ?
The performance I get is somehow less than I expected. How do I control the number of cores ?
How do I check the version of OpenCL ? from commandline ?

Hello,

Intel OpenCL version can be obtained dynamically by querying the OpenCL CPU device version (CL_DEVICE_VERSION) through the clGetDeviceInfo(...) function.

Intel OpenCL supports the Device Fission extension which allows you to control the assignment of work to individual compute units. for more information, see chapter 2.2.1 no our User guide document.

Thanks,
Uri
