A look inside the fastest supercomputer in Europe

What is now the fastest supercomputer in Europe was recently unveiled at a research institute in Jülich, Germany. The computer, named Jugene, is capable of a massive one trillion computing operations per second.
Here are some facts about the Jugene supercomputer:
- Based on IBM’s Blue Gene/P architecture.
- Computing capacity: 1 petaflop/second.
- That equals the computing power of more than 50,000 PCs.
- 294,912 processor cores.
- Processor type: 32-bit PowerPC 450 at 850 MHz.
- 144 terabytes of RAM.
- Mounted in 72 racks.
- Network bandwidth: 5.1 gigabyte/second with a 160 nanosecond latency.
- Power input: 2.2 megawatts.
Wish we could get one of these for Pingdom. Couldn’t cost all that much, could it?
Packing those CPUs tightly together
Each of the Jugene’s 72 racks has 1024 compute nodes, where each node has 2 gigabyte of RAM (totaling 144 terabytes for the whole system). This is what the compute nodes look like and how they are packed together:

For those of you who really want to dive into the nitty-gritty tech specs regarding Jugene’s setup, here’s more info.
Installing Jugene
Looks like there was some cabling involved in the installation process. A LOT of it…


This is most definitely a bit more complicated than plugging in your home computer.

[...] IBM initially developed the Blue Gene family of supercomputers to simulate biochemical processes involving proteins. The Blue Gene/L at the Lawrence Livermore National Laboratory (LLNL) was the world’s fastest computer between November 2004 until 2008 when it lost its crown to another IBM project, the Roadrunner. In its current configuration, the Blue Gene/L at LLNL has 131,072 IBM PowerPC processors running at 700 MHz, a total of 49.1 terabytes of RAM, 1.89 petabytes of disk space and a theoretical peak performance of 367 teraflops. A more beefed up version of the system previously achieved a peak performance of 596 teraflops.
