From Wikipedia: A supercomputer is a computer that is at the frontline of current processing capacity, particularly speed of calculation. Today, supercomputers are typically one-of-a-kind custom designs produced by "traditional" companies such as Cray, IBM and Hewlett-Packard, who had purchased many of the 1980s companies to gain their experience. As of July 2009, the Cray Jaguar is the fastest supercomputer in the world.

The term supercomputer itself is rather fluid, and today's supercomputer tends to become tomorrow's ordinary computer. CDC's early machines were simply very fast scalar processors, some ten times the speed of the fastest machines offered by other companies. In the 1970s most supercomputers were dedicated to running a vector processor, and many of the newer players developed their own such processors at a lower price to enter the market. The early and mid-1980s saw machines with a modest number of vector processors working in parallel to become the standard. Typical numbers of processors were in the range of four to sixteen. In the later 1980s and 1990s, attention turned from vector processors to massive parallel processing systems with thousands of "ordinary" CPUs, some being off the shelf units and others being custom designs. Today, parallel designs are based on "off the shelf" server-class microprocessors, such as the PowerPC, Opteron, or Xeon, and most modern supercomputers are now highly-tuned computer clusters using commodity processors combined with custom interconnects.

The current supercomputer state of the art described in Wikipedia explains exactly what we have done with ICEarth

'''most modern supercomputers are now highly-tuned computer clusters using commodity processors combined with custom interconnects

We are building each ICEarth Bigbang as a highly tuned, highest performing "frontline" computer, running state of the art AMD and i7 processors and industrial-strenght video ards and GPUs, with the latest DDR3 RAM, fastest harddrives and interconnections, and a unique distro of Linux - ICEarth Linux - that may stand-alone (desktop or laptop), or be clustered directly or virtually with other ICEarth computers (and other clouds)

Linux is the most popular operating system among supercomputers

Supercomputers

Linux is the most popular operating system among supercomputers due to its superior performance, flexibility, speed and lower costs. In November 2008 Linux held an 87.8 percent share of the world's top 500 supercomputers.

As of November 2009 the operating systems used on the world's top 500 supercomputers are:

OS Share
Linux 89.2%
Unix 5.0%
Hybrid Unix/Linux 4.6%
Windows HPC 1.0%
BSD 0.2%

In January 2010 Weiwu Hu, chief architect of the Loongson family of CPUs at the Institute of Computing Technology, which is part of the Chinese Academy of Sciences, confirmed that the new Dawning 6000 supercomputer will use Chinese-made Loongson processors and will run Linux as its operating system. The most recent supercomputer the organization built, the Dawning 5000a, which was first run in 2008, utilized AMD chips and ran Windows HPC Server 2008.
