To perform calculations using a GPU the best option is to use the OpenCL standard; Intel offers two implementations:
The first is the Intel® OpenCL SDK: https://software.intel.com/en-us/intel-opencl this implementation is designed to work on Windows.
The other is the Beignet project: http://www.freedesktop.org/wiki/Software/Beignet/ this is an OpenCL open source implementation.
Here are some additional links with more information about OpenCL
I hope this information is useful to you
As you can check on the Beignet page, under the section Supported Targets
- 3rd Generation Intel Core Processors
- Intel “Bay Trail” platforms with Intel HD Graphics
- 4th Generation Intel Core Processors, need kernel patch currently, see the "Known Issues" section.
- 5th Generation Intel Core Processors "Broadwell".
The OpenCL SDK has been replaced by the OpenCL Code Builder, that comes with the Intel® Integrated Native Developer Experience (Intel® INDE), as you can check on the release notes: https://software.intel.com/file/447641/download (page 3), 4th. Gen. Intel Core is also supported by this software.
The patch for Beignet can be found here: Linux kernel patch for HSW support | 01.org
