##HPC at the University of Bristol

Intel has chosen to invest in the University of Bristol to establish its first "Inter Parallel Computing Center (IPCC" in the UK

1. High Performance Computing is enabling fundamental breakthroughs in science, engineering and medicine that will increasingly affect every person on the planet
2. HPC has now broken out of its high-end niche and has gone mainstream
3. All processors becoming both highly paralleland heterogeneous!

#Introduction to programming for HPC

##Lesson #1: Algorithms Matter! ##Lesson #2: Never Guess

> "We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Yet we should not pass up our opportunities in that critical 3%. A good programmer will not be lulled into complacency by such reasoning, he will be wise to look carefully at the critical code; but only after that code has been identified" ¡ª Donald Knuth

##Lesson #3: Memory Hierarchies are Key
