Fastest supercomputer gets faster

Filed under

Blue Gene/L, the fastest supercomputer in the world, has broken its own speed record, reaching 135.5 teraflops - a trillion calculations a second.

That is double the speed it clocked up to take it to the number one spot in the Top 500 supercomputer league.

The IBM Blue Gene machine that achieved the new mark is being assembled for the Lawrence Livermore National Laboratory, a US Department of Energy (DOE) lab.

It did 70.72 teraflops last year to beat Japan's NEC Earth Simulator.

The Blue Gene/L is due to be completed for the Livermore labs in 2005.

We are going to be talking about the first kind of file system here because the average user will interact with his or her file system every time they use a computer, the format that data is written in on their storage devices is usually of little concern to them. The many different file systems that can be used on storage is really only interesting to hardware geeks and is best saved for another discussion. Now that that’s cleared up, we can press on.
