The supercomputers of tomorrow will be capable of feats never thought possible:
model global climate change, run molecular-level simulations of entire
microscopic cells, design nanostructures and more, all very quickly. In fact,
thee team behind these exascale computers are planning to break previous the
energy efficiency record by over half.
They plan to do this, "By combining innovative circuits in
IBM's 32-nanometer silicon-on-insulator complementary metal-oxide-semiconductor
(SOI CMOS) technology with advanced vertical cavity surface emitting lasers
(VCSELs) and photodetectors fabricated by Sumitomo Electric Device Innovations
USA (formerly Emcore)," says Jonathan E. Proesel, an IBM team member. They have
essentially made an optical communication link operating at 25 gigabits per
second using just 24 milliwatts of total wall-plug power, or 1
pJ/bit.
