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 ).

If it … As others have mentioned - what you want to do is use inclusive parallel prefix sum. If you're allowed to use OpenCL 2, they have a workgroup function for it - they should have had it in there from the start because of how often it is used - so now we have everybody implementing it themselves, often poorly in one way or another.
