The sample implements the SAXPY function Y aX Y where X and Y are vectors and a is a scalar. For general issues and bugs with OpenCL in clang refer to Bugzilla. Use the multi_os branch which should allow for running the tutorials on different operating systems programming environments and OpenCL SDKs.
Clang has complete support of OpenCL C versions from 10 to 20. This is one of the most low level wrappers out there. Clang also supports the C for OpenCL kernel language.
For examples 04 and 05 you can run. It can be used in a range of graphics applications such as games CAD design or modeling. To run on CPU you can set it to CL_DEVICE_TYPE_CPU.

The method template cl_int clDevicegetInfocl_device_info name T param gets specific information about the OpenCL device. The information that can be queried is specified in table 43 and in conjunction with table 12. Enqueue_kernel functions that allow you to enqueue kernels from the device and work_group_scan_exclusive_add and work_group_scan_inclusive_add two of a new set of work-group functions that were added to OpenCL 20 to facilitate scan and reduce operations across.
