Top500's 12 November announcement includes an analysis of today's trends in supercomputing. Some highlights:

* Multi-core systems dominate, and more systems (including Titan) are using processor/co-processor architectures.
* Intel provides 76 percent of the supercomputer processors, followed by AMD (12 percent) and IBM (10.6 percent).
* The threshold for membership in the Top 100 list has moved up to 241.3 teraflop per second, up from 172.7 Tflop/s just six months ago.

So here are the world's 10 most powerful supercomputers-for now:

* Titan (Cray XK7)-Oak Ridge National Laboratory, USA: 560 640 cores, 17 590 teraflop per second, 8 209 kilowatts.
* Sequoia (IBM BlueGene/Q)-Lawrence Livermore National Laboratory, USA: 1 572 864 cores, 16 325 Tflop/s, 7890 kW
* K computer (Fujitsu K computer)-RIKEN Advanced Institute for Computational Science, Japan: 705 024 cores, 10 510 Tflop/s, 12 660 kW
* Mira (IBM BlueGene/Q )-Argonne National Laboratory, USA: 786 432 cores, 8162 Tflop/s, 3945 kW
* JUQUEEN (IBM BlueGene/Q)-Forschungszentrum Juelich (FZJ), Germany: 393 216 cores, 4141 Tflop/s, 1970 kW
* SuperMUC (IBM iDataPlex DX360M4)-Leibniz Rechenzentrum, Germany: 147 456 cores, 2897 Tflop/s, 3423 kW
* Stampede (Dell PowerEdge C82207)-Texas Advanced Computing Center, USA: 204 900 cores, 2660 Tflop/s , (power n/a)
* Tianhe-1A ( NUDT YH MPP)-National Supercomputing Center in Tianjin, China: 186 368 cores, 2566 Tflop/s, 4040 kW
* Fermi (IBM BlueGene/Q)-CINECA, Italy: 163 840 cores, 1725 Tflop/s, 822 kW
* DARPA Trial Subset (IBM Power 775)-IBM Development Engineering, USA: 63 360 cores, 1515 Tflop/s, 3576 kW

Bubba says:
It is impressive how many of the top ten are IBM computers, mostly BlueGene, although the top computer is a Cray. I think that its funny that a Dell is on the list -- in a Texas facility.
