Parallelism

We can utilize concurrency to execute a program more efficiently on a multi-core cpuCPU. We will look at some strategies in how to work, it is easy to gain some speed-up but very hard to maintain the speed-up when we increase the number of cores.

¶ We will look at different strategies when paralleliszing a program and when we do so we will work with image transformations. We will start with a colour image and then turn it into a greay scale that in turn will result in something else. This is not a lecture on image transformation but why not do something fun.
