The next challenge: exascale exa peta Performance parallel processing today tera integrated circuits massive parallelism giga mega vacuum tubes transistors kilo 1960 1970 1980 1990 2000 2010 2020 Europe, USA, Japan and China are main global players in this race

Challenges to reach exascale • System power • Memory bandwidth and capacity are not keeping pace with the increase in flops • Cost of data movement • Programming model will be necessary to hide the level of concurrency from applications • The I/O system at all levels will be much harder to manage • Reliability and resiliency will be critical at the scale of billion-way concurrency 8
