2 Outline Why projects? 7th Framework Programme Infrastructure stack IDataCool, CoolMuc Mont-Blanc Poject Deep Project Exa2Green Project 2

3 Why projects? Pave the way for exascale Computing Hypothetical exascale HPC today: 1GW power consumption Cooling and power is listed as number one challenge 3

4 Why projects? Power required to share the data across the chip, node, and cluster. 4

5 Why projects? Many-core architectures are the solution to the short-term scaling problem. 5

6 Why projects? Exascale processing is important 6

7 Why projects? 20 W MW VS
