Vint Cerf, who helped create the web while working as a researcher at Stanford University in the U.S., said the bulk of the remaining IPv4 web addresses will be allocated next spring, which potentially means they will be used up by “sometime in 2012”.
Cerf was speaking at the launch of 6UK, a campaign group to promote the uptake of the new address system, known as IPv6. According to Cerf, IPv6 can host “340 trillion trillion trillion” addresses compared to the 4.3 billion hosted by IPv4.
“So the theory is we won’t run out — at least, not until after I’m dead,” Cerf told The Guardian.
“You need to be able to talk to everyone in the world [who] is on the internet. If Europe doesn’t implement IPv6, it won’t be able to talk to the rest of the world that does implement IPv6 — that’s stupid, and we don’t want people here to be stupid.”
He also said it would be “particularly embarrassing for the U.K.” as it played a key role in developing the web.
IP might finish by 2012, so companies have to start developing for IPv6 fast!!!
In late October, China unveiled the world’s “fastest” super computer, the Tianhe 1A (although blogger Chrisopher Mims has a few important qualifications as to why “world’s fastest” is not entirely accurate). Tianhe 1A runs on more than 7,000 American made nVidia graphics chips and over 14,000 traditional CPUs. It can make well over 1,000 trillion calculations per second and can get up to 4.7 petaflops at peak performance.
And this is all well and good, but around the world there are at several systems currently being planned or under construction that will surpass the Tianhe 1A in power and speed. In the U.S., the University of Illinois’ National Center for Supercomputing Applications is developing a system called Blue Waters, which will be capable of at least 1 petaflop of sustained performance, and up to 10 petaflops at peak performance.
Running on power7 multicore processors from IBM, the system also boasts super efficient interconnect chip technology that will serve as a gateway between the power7 processors and allows the processors to communicate with each other. All this power will be devoted to scientific research: from making predictions in biology and astrophysics, to simulating engineered systems.
The Lawrence Livermore National Laboratory is also working with IBM to create a 20 petaflop supercomputer called “Sequoia” that will gear up in 2011 and be running quadrillions of scientific computations per second in 2012. This supercomputer will take over the duties of running the weapons simulation codes to “ensure the safety, security, and reliability” of nuclear weapons in America. (according to a 2003 paper submitted by the Lawrence Livermore National Laboratory). Looks like China’s going to need a few more processors.
