Question 3 The advantage of using SSE SIMD is: O You should be able to get a 4x performance improvement in array multiplication O You can perform a multiply and an add in one instruction O It uses a stack variable to hold each multiplication product O It uses the stack to hold its pointers 2.5 pts U Question 5 When OpenCL and OpenGL work together: O They take turns accessing the vertex buffer O It is just OpenGL that is able to access the vertex buffer O They both access the vertex buffer at the same time O It is just OpenCL that is able to access the vertex buffer 2.5 pts
