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: Mobile and Desktop Products: - third Generation Intel® Core"! i7 Extreme Processors - third Generation Intel® Core"! i7 Processors - third Generation Intel® Core"! i5 Processors - third Generation Intel® Core"! i3 Processors - second Generation Intel® Core"! i7 Extreme Processors - second Generation Intel® Core"! i7 Processors - second Generation Intel® Core"! i5 Processors - second Generation Intel® Core"! i3 Processors - first Generation Intel® Core"! i7 Extreme Processors - first Generation Intel® Core"! i7 Processors - first Generation Intel® Core"! i5 Processors - first Generation Intel® Core"! i3 Processors Server Products: - Intel® Xeon® Processors E7 Family - Intel® Xeon® Processors E5 Family - Intel® Xeon® Processors E3 Family - Intel® Xeon® Processors, 7500, 7400, 6500 series - Intel® Xeon® Processors, 5500 series - Quad-Core Intel® Xeon® Processor 5400, 3300 series - Dual-Core Intel® Xeon® Processor, 5200, 3100 series Intel® SDK for OpenCL* - CPU Only Runtime Package supports the following operating systems: - Microsoft Windows 7* (32-bit version) - Microsoft Windows 7* (64-bit version) - Microsoft Windows 7* Service Pack 1 (32-bit version) - Microsoft Windows 7* Service Pack 1 (64-bit version) - Microsoft Windows Vista* Service Pack 2 (32-bit version) - Microsoft Windows Vista* Service Pack 2 (64-bit version) - Microsoft Windows 8* Release Preview OS 32-bit and 64-bit versions Use Microsoft Windows 7* operating systems with Service Pack 1 to achieve better performance on 2nd Generation Intel® Core"! processors. 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) For specifications of Khronos and vendor-approved OpenCL extensions please visit the Khronos OpenCL API Registry (http://www.khronos.org/registry/cl/) Intel® SDK for OpenCL* Applications is available for downloading through Intel® Software Network (http://software.intel.com/en-us/articles/vcsource-tools-opencl-sdk/) * OpenCL and the OpenCL logo are trademarks of Apple Inc. used by permission by Khronos.

After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
