Top 5 Fastest Supercomputers in the world
Supercomputers are used for scientific and engineering problems as diverse as climate simulation and automotive design. A supercomputer is a computer that is at the frontline of current processing capacity, particularly speed of calculation. Supercomputers are used for highly calculation-intensive tasks such as problems involving quantum physics, weather forecasting, climate research, molecular modeling. Supercomputers using custom CPUs traditionally gained their speed over conventional computers through the use of innovative designs that allow them to perform many tasks in parallel, as well as complex detail engineering. On Monday, the most recent list of the world's top 500 fastest supercomputers was announced at the 2011 International Supercomputing Conference in Hamburg, Germany. Here is the list of the top five.
K Computer:
Fujitsu-made "K Computer," installed at the RIKEN Advanced Institute for Computational Science in Japan. This massive processing powerhouse runs on 548,352 cores (68,544 CPUs with eight cores each). K computer system, currently in the configuration stage, has 672 computer racks equipped with a current total of 68,544 CPUs.
Tianhe-1A :
The Chinese supercomputer Tianhe-1A bagged the second place in the list. A whopping 50-percent faster than the previous record holder, Tianhe-1A scores 2.507 petaflops in LINPACK benchm arking despite being half the size of a regular supercomputer.Tianhe-1A Supercomputer is located at National Supercomputer Center, Tianjin. NVIDIA GPUs can each be set to work doing the task of several equivalent CPUs.
Jaguar:
Jaguar is a petascale supercomputer built by Cray at Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tennessee. The massively parallel Jaguar has a peak performance of just over 1,750 teraflops (1.75 petaflops). It has 224,256 x86-based AMD Opteron processor cores, and operates with a version of Linux called the Cray Linux Environment.
Nebulae:
Dawning has manufactured some of the fastest supercomputers in the world including Nebulae, the second fastest computer in the June 2010 TOP500 list. The Dawning Nebulae, based at the National Supercomputing Center in Shenzhen, China, has achieved a sustained computing speed of 1.27 petaflops - the equivalent of one thousand trillion mathematical operations. It is currently the third most powerful supercomputer in the world and China's second most powerful.
TSUBAME2.0:
TSUBAME2.0 is the latest supercomputer, featuring, among others, national-first petaflop performance with very large-scale GPU acceleration, massive parallel storage, and highly pow er-efficient designs. This is the second generation of our TSUBAME-series machines, and is designed and constructed based on experiences with the previous supercomputer, TSUBAME1. Tsubame 2.0 is built to hit the 2.4 petaflop level using mixed technologies from Intel, HP, NVIDIA and contracting from NEC.
