3. •Why? •Concurrency vs Parallelism •Parallella vs Mac •FPGAs •Questions Journey
4. Why?
5. What can we do now that we could not do before?
 How do we show the difference visually?
6. What can we do in parallel that we cannot do serially?
 How do we show the difference visually? Parallel: So what?
7. Moore’s Law: 2x every 18 months
8. Moore’s Law: 2x every 18 months 1993 http://www.washingtonpost.com/blogs/innovations/wp/ 2015/04/14/10-images-that-explain-the-incredible-power-of- moores-law/ 2013
9. Parallelism
10. If one ox could not do the job they did not try to grow a bigger ox, but used two oxen. When we need greater computer power, the answer is not to get a bigger computer, but to build systems of computers and operate them in parallel. -Grace Hopper
11. Concurrency is not Parallelism. https://www.youtube.com/watch?v=cN_DpYBzKso&list=PLOnWKC1gI_OPU8SDIBnCLHsgzNLSbnPJQ&index=3 -Rob Pike, Go
12. Concurrency At least two threads are making progress. Parallelism At least two threads are executing simultaneously. Oracle Multithreaded Programming Guide http://docs.oracle.com/cd/E19455-01/806-5257/6je9h032b/index.html vs.
