1. 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_extend�
