First supercomputer built from commodity hardware
Start of broadly available computing resources era
Progress is huge
Computers help tosolve problems once unsolvable
HPC is now
cheaper than ever,easier than ever,
more accessible than ever
Computational revolutionScience: Human Brain Project
Computers help tosolve problems once unsolvable
50 PFLOPs for modeling of mouse brain
1 EFLOPs for modeling of human brain
Computational revolutionScience: CERN IT infrastructure
Computers help tosolve problems once unsolvable
15 PBytes of data annually at LHC, global tiered infrastructure
1 Tier 0, 11 Tier 1, 140 Tier 2 sites
