WebImplement the SAXPY routine in OpenCL. SAXPY can be called the "Hello World" of OpenCL. In the simplest terms, the first OpenCL sample shall compute A = alpha*B + C, where alpha is a constant and A, B, and C are vectors of an arbitrary size n. In linear algebra terms, this operation is called SAXPY ( Single precision real Alpha X plus Y ).
