Introduction to parallel programming

Hands-on starting from a Python image processing code, offloading hot spot to a C function, and optimizing it using OpenMP task parallelism, then OpenMP data parallelism, and finally vector instructions.

⇒ Subject / Source and results

Here are some results on a dual-X5670 (2×6 cores @2.9GHz):

From naive python to naive C: 233x
From naive C to task based parallelism: 2.1x (493x over python)
From task based parallelism to data parallelism: 7.6x (3758x over python)
From data parallelism to SSE2 vectorizing: 13.46x (50612x over python)
