Lecture 12

Learning objectives

After this class, you should be able to:

1. Use SSE instructions to optimize the performance of code on Intel x86 processors.
2. Use SIMD instructions to optimize the performance of code on SPEs of the Cell processor.

Reading assignment

1. Refer to the following Cell related documents on Blackboard: (i) SPE extensions and (ii) Cell SIMD Math. Refer to the Intel compiler intrinsics reference mentioned in the Lecture 12 slides.

Exercises and review questions

• Exercises and review questions on current lecture's material

  1. Use SSE instructions to improve the performance of your matrix multiplication code on linprog. Report your results on the discussion board, under the Lecture 12 thread.

  2. Use SIMD instructions to improve the performance of your matrix-vector multiplication code on the Cell processor.

• Preparation for the next lecture
  1. None.
