clwrap.hpp is a convenient header file for wrapping OpenCL host boilerplate procedure.

After checking out this repository, please source a proper OpenCL environment first, then make and run it using the OpenCL emulator for a quick functional verification.

NOTE:

• By default, it finds the platform name contains "Intel". The platform search keyword can be changed using the CLW_PF environment variable. For example, $ CLW_PF=Altera ./yourclwraphostcode
