Installing Intel CPU OpenCL on Ubuntu 12.04
Open Computing Language (OpenCL) is a language and framework for writing computationally intensive kernels that run accross heterogenious platforms, including GPUs, CPUs, and perhaps other more esoteric devices.
Intel provides an OpenCL implementation for Intel CPUs, but there's not a lot of instructions on how to get it set up. Here's what I did.
- Download the Intel® SDK for OpenCL* Applications XE 2013 from the Intel website, here http://software.intel.com/en-us/vcsource/tools/opencl-sdk-xe. The download is a tarball -- the one I got is called
intel_sdk_for_ocl_applications_2013_xe_sdk_3.0.67279_x64.tgz - Unpack the tarball and cd into the new directory
