MPPs

•  Performance on massively parallel machines –  Larger problem sizes, i.e. sizes that make sense –  Performance numbers reflect the largest problem run on a given

machine

•  Rmax –  the performance in Gflops for the largest problem run on a

machine •  Nmax

–  the size of the largest problem run on a machine •  N1/2

–  the size where half the Rmax execution rate is achieved •  Rpeak

–  the theoretical peak performance in Glops for the machine


Linpack benchmark

•  Pros –  One number: Rmax –  Simple to define and and use to rank –  Allows problem size to change with machine and over time

•  Cons –  Emphasizes only “peak” speed and number of CPUs –  Does not stress the networks –  Ignores Amdhal’s Law (changing problem size when more CPU

are exploited)

•  The K Computer, built by Fujitsu, currently combines 68544 SPARC64 VIIIfx CPUs, each with eight cores, for a total of 548,352 cores—almost twice as many as any other system in the TOP500. The K Computer is also more powerful than the next five systems on the list combined.

•  The K Computer’s name draws upon the Japanese word "Kei" for 10^16 (ten quadrillions), representing the system's performance goal of 10 petaflops. RIKEN is the Institute for Physical and Chemical Research.

•  Unlike the Chinese system it displaced from the No. 1 slot and other recent very large system, the K Computer does not use graphics processors or other accelerators. The K Computer is also one of the most energy-efficient systems on the list.


China builds petaflop supercomputer without AMD, Intel or Nvidia Oct 31 2011 COMMUNIST China has built its first supercomputer using chips designed and manufactured in China instead of relying on AMD, Intel or Nvidia. China's new Sunway Bluelight MPP was installed in the country's National Supercomputer Center in Jinan in September, with estimates pegging the cluster somewhere around the petaflop mark. The cluster is made up of 8,700 Shenwei SW1600 processors, which are completely designed and manufactured in China. China's past success in the HPC arena has been down to good old fashioned American technology. The chips might have been baked in China but the design was done by US-based firms. The 8,700 Shenwei SW1600 processors represent the country's first comprehensive design and construction effort to build a large scale HPC cluster. Since the TOP500 list and supercomputers in general are often viewed as objects of national pride, it's no surprise that China wants to produce its own supercomputer. While the Shenwei cluster isn't quite ready to usurp Japan's K-Computer, few will bet against China heading the TOP500 list with its own chips before too long.
