With the biannual list of the top 500 supercomputers the world over released, the following screenshot of a graph showing the operating systems used in those 500 peta-flop crunching machines, and produced by the University of California Berkeley, makes for an impressive visual glance at Linux’s dominance in Super Computing.
I never get tired of mentioning the fact that Linux supports more hardware and is on more devices than any other operating system I know of. It runs on anything from the largest super computers in the world to a computer smaller than a matchbox. In short practically the whole world is supported by Linux.
For decades, supercomputers have helped scientists perform calculations that would not have been possible on regular computers of that time. This post pays tribute to some of the most powerful supercomputers the world has seen, all the way from the 1970s until today.
Supercomputers around the world are running on SUSE Linux Enterprise Server from Novell. According to TOP500, a project that tracks and detects trends in high-performance computing, SUSE Linux Enterprise is the Linux of choice on the world's largest HPC supercomputers today.
I carry a small, laminated card indicating my subscription to the IUSP (International Union of the Super Paranoid, tin hat division). Well, you can't be too careful. After all, we live in a dangerous world and computers are just an extension of that.
Selling businesses on the benefits of Linux has been a tough proposition for many years. Common reasons cited for not moving to the open-source operating system include system complexity, lack of in-house IT skills and a shortage of business applications.
In fact, buying Linux and learning how to use it are easier than ever, thanks to the open-source operating system's expanding presence in affordable computers and mainstream retail outlets.
What do the BlueGene/L System, the BlueGene/P system and the New Mexico Computing Applications Center SGI system, based on the Altix ICE Integrated Compute Environment 8200 model, have in common? First, they're the top three fastest computers in the world, according to the latest Top 500 supercomputer list. Second, they all run Linux.
