Linux is speed and power

Man, what a busy time lately!!... I have struggled big time to finish any of my ongoing articles, but fear not, this blog is very much alive and kicking. Stay tunned for upcoming articles, for there are some interesting things on the way, including reviews for Fedora 15, Fuduntu 14.10, Zorin 5 OS and (maybe) an article on why I decided not to review Ubuntu 11.04 and Unity.

While I finish those reviews, I thought I'd share an interesting International Business Times ARTICLE which lists the 10 most powerful computers on Earth today. The piece that I find particularly interesting is that ALL TEN OF THEM RUN LINUX! (Go Tux!)

Here's the list:

1. K Computer, Japan

Built by Fujitsu, the Japanese supercomputer at the RIKEN Advanced Institute for Computational Science (AICS) in Kobe, is capable of performing more than 8 quadrillion calculations per second (petaflop/s). “The K Computer is also more powerful than the next five systems on the list combined and also one of the most energy-efficient systems on the list.”

2. Tianhe-1A, China

The Chinese supercomputer at the National Supercomputing Center in Tianjin, China, performs at 2.6 petaflop/s.

3. Jaguar, United States

The Jaguar, a Cray supercomputer at the U.S. Department of Energy’s (DOE’s) Oak Ridge National Laboratory, is ranked No. 3 with 1.75 petaflop/s.

4. Nebulae, China

The Nebulae supercomputer at China’s National Supercomputing Center in Shenzen is ranked fouth with 1.27 petaflop/s performance.

5. Tsubame 2.0, Japan

Tsubame 2.0 at the Tokyo Institute of Technology is fifth most fast supercomputer in the world with 1.19 petaflop/s performance.

6. Cielo, United States

The Cielo supercomputer at Los Alamos National Laboratory in New Mexico performs at 1.11 petaflop/s.

7. Pleiades, United States

Pleiades, located at NASA's Ames Research Center in Moffett Field, California, allows over 1,000 active users around the country advance knowledge about the Earth, solar system and the universe. Pleiades helps meet computing needs of NASA's aeronautics projects and other space operations. It has a performance at 1.09 petaflop/s.

Pleiades Westmere-based racks: The addition of the Westmere and Nehalem nodes increased the computing capacity available on Pleiades by 170%.

8. Hopper, United States

The Hopper supercomputer, located at DOE’s National Energy Research Scientific Computing Center (NERSC) in California, is ranked eighth with 1.054 petaflop/s performances.

9. Tera 100, France

Tera 100 at the CEA (Commissariat à l'énergie atomique et aux énergies alternatives) in France performs at 1.05 petaflop/s.

10. Roadrunner, United States

Roadrunner at Los Alamos National Laboratory in New Mexico performs at 1.04 petaflop/s.

So there you have it, our tux penguin may look harmless, but it can turn your PC into a mean muscle machine if you ask it to!


  1. I thought I'd heard that the K-computer was running Solaris... Now I'll have to go check.

  2. OK I had to dig down in the report, but the K system is indeed listed as running linux. Very interesting choice of hardware platform and OS...

  3. kickass headline, hats off :D

    Slowlaris died a painfull dead long time ago. Almost nobody runs it on supercomputers.
