The K computer, named after the Japanese word "kei", which stands for 10 quadrillion, is a supercomputer being produced by Fujitsu at the RIKEN Advanced Institute for Computational Science campus in Kobe, Japan.

Summary: The S-1 project was an attempt to build a family of multiprocessor supercomputers. The project was envisioned by Lowell Wood at the Lawrence Livermore National Lab in 1975 and staffed for the first three years by two Stanford University Computer Science graduate students, Tom McWilliams and Curt Widdoes.

EKA is a supercomputer built by the Computational Research Laboratories with technical assistance and hardware provided by Hewlett-Packard. When it was installed in November 2007, it was the 4th fastest in the world and fastest in Asia. As of November 2010, it is ranked as the 47th fastest in the world and fourth fastest in Asia. Eka is the Sanskrit name for number one.

PARAM is a series of supercomputers designed and assembled at the Centre for Development of Advanced Computing (C-DAC) in Pune, India. The latest machine in the series is the PARAM Yuva, which reached no. 109 on the TOP500 in June 2009. Others include PARAM 10000 and PARAM 9000/SS and the PARAM Padma. The PARAM Padma was India's first Teraflop supercomputer. Currently, C-DAC is developing a Petaflop Supercomputer which is expected to be in operation by 2012. The biggest challenge in designing the $125 million supercomputer is handling the power consumption of the unit which is expected to be around 20MW up from the current 1MW consumption of the PARAM Yuva cluster. However, the new machine will also be able to perform up to 100 times more computations per second than the current PARAM Yuva cluster.

The TOP500 project ranks and details the 500 (non-distributed) most powerful known computer systems in the world. The project was started in 1993 and publishes an updated list of the supercomputers twice a year. The first of these updates always coincides with the International Supercomputing Conference in June, and the second one is presented in November at the ACM/IEEE Supercomputing Conference. The project aims to provide a reliable basis for tracking and detecting trends in high-performance computing and bases rankings on HPL, a portable implementation of the High-Performance LINPACK benchmark written in Fortran for distributed-memory computers.

In order to run weather forecast models within a schedule that has reasonably short timeslots, powerful supercomputer systems are required.. The first version of the ECMWF weather forecasting model was developed on a Control Data Corporation 6600 computer from 1976 to 1978. Although the CDC6600 was one of the most powerful systems available at the time, the forecast model still needed 12 days to produce a 10-day forecast. However, this showed that provided a suitably powerful computer could be acquired, useful forecasts could be produced.

Go is a compiled, garbage-collected, concurrent programming language developed by Google Inc. The initial design of Go was started in September 2007 by Robert Griesemer, Rob Pike, and Ken Thompson. Go was officially announced in November 2009. In May 2010, Rob Pike publicly stated that Go was being used "for real stuff" at Google. Go's "gc" compiler targets the Linux, Mac OS X, FreeBSD, and Microsoft Windows operating systems and the i386, amd64, and ARM processor architectures.
