<EFBFBD><EFBFBD>1. About Intel<00> SDK for OpenCL* - CPU Only Runtime Package.
Intel<00> 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<00> SDK for OpenCL* - CPU Only Runtime Package requires support for the Intel<00> Streaming SIMD Extensions 4.2 (Intel<00> SSE 4.2) or higher (Intel Intel<00> Advanced Vector Extensions (Intel<00> 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<00> Core"! i7 Extreme Processors
- third Generation Intel<00> Core"! i7 Processors
- third Generation Intel<00> Core"! i5 Processors
- third Generation Intel<00> Core"! i3 Processors
- second Generation Intel<00> Core"! i7 Extreme Processors
- second Generation Intel<00> Core"! i7 Processors
- second Generation Intel<00> Core"! i5 Processors
- second Generation Intel<00> Core"! i3 Processors
- first Generation Intel<00> Core"! i7 Extreme Processors
- first Generation Intel<00> Core"! i7 Processors
- first Generation Intel<00> Core"! i5 Processors
- first Generation Intel<00> Core"! i3 Processors
Server Products:
- Intel<00> Xeon<00> Processors E7 Family
- Intel<00> Xeon<00> Processors E5 Family
- Intel<00> Xeon<00> Processors E3 Family
- Intel<00> Xeon<00> Processors, 7500, 7400, 6500 series
- Intel<00> Xeon<00> Processors, 5500 series
- Quad-Core Intel<00> Xeon<00> Processor 5400, 3300 series
- Dual-Core Intel<00> Xeon<00> Processor, 5200, 3100 series
Intel<00> 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<00> 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<00> 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)
