ÿþ1. About Intel® SDK for OpenCL* - CPU Only Runtime Package.



Intel® SDK for OpenCL* - CPU Only Runtime Package is an implementation of the OpenCL 1.2 standard optimized for Intel processors, running on Microsoft Windows* operating systems. 



2. Technical Requirements



Intel® SDK for OpenCL* - CPU Only Runtime Package requires support for the Intel® Streaming SIMD Extensions 4.2 (Intel® SSE 4.2) or higher (Intel Intel® Advanced Vector Extensions (Intel® AVX)). SDK works on the following CPUs, all of which contain support for the required instruction set extensions:

3. Supported features



3.1 Conformant with OpenCL 1.2 specification for the CPU, and with Microsoft Windows 7* operating systems.



3.2 Optional OpenCL 1.2 Standard Features

- Out-of-order execution model as defined in the OpenCL specification (CL_QUEUE_OUT_OF_ORDER_EXEC_MODE_ENABLE property of a command queue).

- Execution of native kernels as defined in the specification (CL_EXEC_NATIVE_KERNEL option of the CL_DEVICE_EXECUTION_CAPABILITIES property of device information).

- Image support with the minimum set of image formats, as defined in the specification (CL_DEVICE_IMAGE_SUPPORT property of device information).

- Optimization options: Intel® OpenCL SDK supports the OpenCL standard compiler flag -cl-fast-relaxed-math. Some optimizations may violate the IEEE 754 standard and the OpenCL numerical compliance. For a full list of optimized functions see Working with the cl-fast-relaxed-math Optimization Flag.

- Math intrinsic option: supports standard optional compiler flag -cl-denorms-are-zero.



3.3 OpenCL 1.2 Conformant Extensions

- cl_khr_icd - defines a simple mechanism through which the Khronos installable client driver loader (ICD Loader) may expose multiple separate vendor installable client drivers (Vendor ICDs) for OpenCL

- cl_khr_fp64 - double precision floating point support, as defined in the specification.

- cl_khr_gl_sharing - creating OpenCL context from an OpenGL* context or share group, as defined in the specification. This extension is supported on Microsoft Windows* operating systems only.

- cl_khr_gl_sharing - sharing memory objects with OpenGL* or OpenGL* ES buffers, texture and render bugger objects, as defined in the specification. 

- cl_khr_global_int32_base_atomics

- cl_khr_global_int32_extended_atomics

- cl_khr_local_int32_base_atomics

- cl_khr_local_int32_extended_atomics

- cl_khr_byte_addressable_store

- cl_khr_dx9_media_sharing

- cl_khr_d3d11_sharing



3.4 OpenCL cl_ext Extensions

- Intel Device Fission Extension Support (cl_ext_device_fission)



3.5 Intel Vendor Extensions

- Intel Immediate Command Execution Extension (cl_intel_exec_by_local_thread)

- Intel DirectX* 9 Media Sharing Extension (cl_intel_dx9_media_sharing)
