Nerd Vacation to the Earth Simulator
eecue writes "Earlier this year I went on vacation to japan. At the end of my trip I was lucky enough to receive a tour of the Earth Simulator, which is the world's fastest super computer. I took pictures and wrote about it."
Well that would, of course, depend on how much bandwith is running to said server now wouldn't it? =)
Found some nice info (good old google) on said Supercomputer though since the sites linked article didn't have much.

A snippet(s) of info:
"Based on the NEC SX architecture, 640 nodes, each node with 8 vector processors (8 Gflop/s peak per processor), 2 ns cycle time, 16GB shared memory. Total of 5120 total processors, 40 TFlop/s peak, and 10 TB memory. "
"Earth Simulator's processors are one-chip LSIs fabricated with 0.15 micron CMOS process and copper wiring. Highly optimized software and high-speed networks that pump massive amounts of data through 7.8TB/s bandwidth connecting the 640 processing nodes are key to the amazing efficiency of Earth Simulator."
Looks like it's been #1 since at least June of last year.

blasphemer! have you even read the sacred text which you so blithly profane?
they already knew the answer before they built the earth. Earth's job was to calculate the question. ofc, since the golgafrinchins (sic?) showed up early in the process, we've completly screwed up the calculation.

As far as the command set goes it's a vector processor. That means it has an instruction set that is completely unlike any standard scalar (Von Neumann) archictecture processor you may be familiar with. The CRAY series of supercomputers were one of the first vector processors around; do a google search for "CRAY Instruction Set Reference Card" and have a look. That will give you some insight on how a vector processor is programmed. Most instructions support 3 operands - 2 source and a destination argument.

Just because the n-ary representation of pi is infinite does not mean that all sequences will occur in it, and this has in fact not yet been proven.
There's a big difference between weather forcasting and climate forcasting.
Nonsense. Think of a number that's looks like the binary expansion of Pi (ie just 1's and 0's), but in base 10.This'd be non repeating, irrational, not representable as a finite function (for suitable definitions of 'a finite function), and yet I can assure you you won't find the sequence 123456 in it.
