Last week, the US Department of Energy and IBM unveiled Summit, America's latest supercomputer, which is expected to bring the title of the world's most powerful computer back to America from China, which currently holds the mantle with its Sunway TaihuLight supercomputer.
With a peak performance of 200 petaflops, or 200,000 trillion calculations per second, Summit more than doubles the top speeds of TaihuLight, which can reach 93 petaflops. Summit is also capable of over 3 billion billion mixed precision calculations per second, or 3.3 exaops, and more than 10 petabytes of memory, which has allowed researchers to run the world's first exascale scientific calculation.
The $200 million supercomputer is an IBM AC922 system utilizing 4,608 compute servers containing two 22-core IBM Power9 processors and six Nvidia Tesla V100 graphics processing unit accelerators each. Summit is also (relatively) energy-efficient, drawing just 13 megawatts of power, compared to the 15 megawatts TaihuLight pulls in.
There's something mesmerizing about supercomputers like these. I would love to just walk through this collection of machines.
