Congratulations!

Congratulations to everybody, every participan and scientist member of the projetct. We are looking for new exciting reports on this (and previous S4) run and looking forward to win in this competition with physics enigma.
BTW, it will be very interesting to place in server status page a volume of calculations made measured not only in TFLOPs, but by the productivity of the TOP supercomputer in the world (sorry, I don't know the power and name of the most powerful supercomputer). Is it possible?

I think it is IBM BluGene/L (280.6 teraflops). But the 37000 odd PS3 crunching Folding@home have reached almost 1 petaflop.

On October 27, 2005, LLNL and IBM announced that Blue Gene/L had once again broken its speed record, reaching 280.6 TFLOPS on Linpack, upon reaching its final configuration of 65,536 "compute nodes" (i.e., 216 nodes) and an additional 1024 "I/O nodes" in 64 air-cooled cabinets. The LLNL Blue Gene/L uses Lustre to access a 900TB filesystem.

Each Compute or I/O node is a single ASIC with associated DRAM memory chips. The ASIC integrates two 700 MHz PowerPC 440 embedded processors, each with a double-pipeline-double-precision Floating Point Unit (FPU), a cache sub-system with built-in DRAM controller and the logic to support multiple communication sub-systems. The dual FPUs give each BlueGene/L node a theoretical peak performance of 5.6 GFLOPS (gigaFLOPS). Node CPUs are not cache coherent with one another.

On June 26, 2007, IBM unveiled Blue Gene/P, the second generation of the Blue Gene supercomputer. Designed to run continuously at 1 PFLOPS (petaFLOPS), it can be configured to reach speeds in excess of 3 PFLOPS. Furthermore, it is at least seven times more energy efficient than any other supercomputer, accomplished by using many small, low-power chips connected through five specialized networks. Four 850 MHz PowerPC 450 processors are integrated on each Blue Gene/P chip. The 1-PFLOPS Blue Gene/P configuration is a 294,912-processor, 72-rack system harnessed to a high-speed, optical network. Blue Gene/P can be scaled to an 884,736-processor, 216-rack cluster to achieve 3-PFLOPS performance. A standard Blue Gene/P configuration will house 4,096 processors per rack. The first laboratory to receive the Blue Gene/P will be Argonne National Laboratory. The first racks of the Blue Gene/P will be shipped in fall 2007. The first installment will be a 111-teraflop system, which has approximately 32,000 processors, will be operational for the national community in spring 2008.

The last known supercomputer in the Blue Gene series, Blue Gene/Q is aimed to reach 10 PFLOPS in the 2010-2012 time frame. It will continue to expand and enhance the Blue Gene/L and /P architectures with higher frequency at similar performance/watt. Blue Gene/Q will have a similar number of nodes but many more cores per node.
