OpenCL supports a wide range of data types derived from the C programming language. They are widely classified into two groups called scalars and vectors. Scalars are basically elemental values, whereas vectors are a collection of elemental values and a good thing about vectors is that many OpenCL SDK vendors have provided automated vectorization which allows the values to be loaded into wide, that is, 128-bit, 256-bit, or 512-bit registers for consumption.
