Kernel: saxpy

Write a device kernel that calculates the single precision BLAS operation saxpy, i.e. y = a * x + y.

• Initialise the vectors x and y with some values on the CPU
• Perform the computation on the host to generate reference values
• Allocate memory on the device for x and y
• Copy the host x to device x, and host y to device y
• Perform the computation on the device
• Copy the device y back to the host y
• Confirm the correctness: Is the host computed y equal to the device computed y?

You may start from a skeleton code provided in saxpy.cpp.
