this final. Start immediately. And now show that you mastered 357 and good luck!


Write an mpi – controlled parallel program which calculates the matrix multiplication result of two
images and stores this into a result image. You will find three images: f0, f1 and f2. They are
quadradic, meaning width equals height. Read image f1 and f2, normalize the colors and make a
matrix multiplication, by using their colors as matrix elements.

Do this for red, green and blue.
Your program should work with 1, 2, 4 and 8 instances. Measure and print the time it takes for the
calculation on the screen. Save the result image. Your result image will overflow the byte
limitation. I recommend multiplying the result colors with 0.03 before casting it into a byte.


Let me know how you interpret the result on Piazza. No points for this, but its essential for image
processing. Also, if you want, exchange f2 with f0. This is relevant for AI image recognition. Yes,
you already are capable of doing so much!
